Indian Forester, Vol 129, No 8 (2003), Pagination: 950-963Abstract
Conservation of medicinal/aromatic plants and the environment will be possible only with the precondition that our political leadership and policy makers become alive to this problem and take some really strong decisions. Since the Forest Department has to play a major role in this initiative by virtue of being the dominant custodian of the patural resource of land and forest, it should be ready for a major attitudinal change in favour of an ecosystems approach to forestry. The public of Uttaranchal are the predominant stakeholders, and will have to assert themselves against the threat of grazing, pilferage and fire. Our scientists and NGOs also have to playa very important role in this strategy of in-situ and ex-situ revival of medicinal plants. In addition to the others, the industry is expected to adopt a role that is beneficial to all stakeholders. The Bhagirathi valley is endowed with a rich wealth of medicinal and aromatic plants ranging from Sub Tropical to Alpine species. This invaluable resource is, however, under serious threat from severe depletion due to grazing, pilferage, fire and social indiscretions in utilization. Eight mega centers for the conservation of medicinal plants have been suggested which need to be protected by establishment of MPCAs. This insitu intervention needs to be closely dovetailed with ex-situ cultivation and conservation along with Eco Tourism as a major part of the strategy. In pursuance of this goal, seven medicinal plant gene repositories have been raised with over 200 important medicinal plant species. Other important issues closely related to the development of Uttaranchal as a herbal state are Research, for propagation and conservation, Standardisation of herbal produce, the need for strong regulations against unlawful removal from the forests, patenting of traditional knowledge and formulations, and, last but not the least, the necessity to organize a transparent market. With proper planning and a concerted effort from all the stakeholders, specially the political leadership and the policy makers, Uttaranchal stands a fair chance of garnering a major share of the national and international market of medicinal and aromatic plants.

Present study was carried out (n=120) to find out the various channels involved in the marketing of guava fruits and to study the constraints encountered by the guava farmer of Kaushambi district of Uttar Pradesh. The average family size of guava farmers was 5.25 with average male and female 2.8 and 2.44, respectively. Average literacy rate among the famers families was 43.49.However, 30.42 per cent male and 26.08 per cent female were illiterate. There were seven different types of marketing channels which were involved in guava marketing. Out of seven marketing channels involved in guava marketing, first channel was found to be efficient and the remaining were less efficient in farmer's share in consumer price. Farmers faced several constraints related to marketing, storage and financial problems. High involvement of middleman's is hampering the profitability of guava farmers. Guava farmers are facing several constraints related to marketing, storage and finance. Hence, to improve the productivity of guava farm and guava farmers, the constraints and problems should be resolved at priority basis. Therefore, policy makers and administrators have to take initiative to provide efficient services to benefit the producers.Keywords

Synthetic aperture radar (SAR) signals penetrate through the dry snow and cloud providing crucial data over the Himalayan temperate glaciers and complement the optical images. In the present study, RISAT-1 C band and AWiFS images of winter/ablation period over Samudra Tapu and Gepang Gath moraine dammed lakes (MDLs) in Himachal Pradesh have been analysed. Backscattering coefficient of the lake was observed to be low throughout the year. Penetration depth of SAR into dry snowpack was calculated to vary from 4 to 22 m for a range of snow density (0.1-0.5 g/cm3), whereas it was estimated to be 1.20- 2.01 m based on ground observations for 30 January and 24 February 2013. The present study provides results of RISAT-1 C-band penetration up to ~2 m through the snowpack to detect MDLs in the Himalayan terrain. The detection of MDLs using the backscattering images of winter season was validated with synchronous AWiFS sensor images.Keywords

Monitoring of lakes in glaciated terrain in the Himalayan region has been recognized as one of the priority areas especially after the Kedarnath disaster. Among all types of glacial lakes, moraine dammed lakes (MDLs) are the most important from disaster point of view. Remote sensing plays a significant role in view of availability of unbiased repeated data on the expansion or contraction of MDLs located in rugged terrains of the Himalaya. Monitoring of two MDLs, associated with Katkar and Gepang-gath glaciers in Zanskar and Chandra sub-basins respectively was done using satellite images of 1965, 1976, 1989, 2001, 2006-07, 2012 and 2014. Survey of India (SOI) topographical maps of 1962 were also referred to monitor the respective glaciers lakes. SOI maps show the presence of only one lake associated with Gepang-gath glacier. Areal extent of the MDLs had increased from 21 to 57 ha between 1965 and 2014, and from 27 to 80 ha between 1962 and 2014 for the Katkar and Gepang-gath glaciers respectively. Increase in peak discharge of the two lakes was also estimated using different empirical models in case of outbursts of these lakes. The lake outburst probability for both these lakes was found to be very low (less than 1%), however, possibility of outburst of lakes due to natural calamity like cloud burst, landslide or earthquake cannot be ignored. The rate of retreat of these two glaciers was observed to be high due to the presence of MDLs in comparison to surrounding glaciers in the valley.Keywords

This article presents highlights of the research work done in hyperspectral remote sensing in the Himalayan cryosphere. Hyperspectral radiometric investigations conducted at different field locations of NW Himalaya and cold laboratory are discussed. Spectral signatures were collected for varying snow grain size, contamination, liquid water content, vegetation/soilmixed snow, glacier ice, moraines and other ambient objects. The important wavelengths for snow applications are found to be 440, 550, 590, 660, 860, 1050, 1240 and 1650 nm. Further, the retrieval of snow parameters such as grain size, spectral albedo and snow contamination using imaging data at the above wavelength channels is discussed. Wavelengths 550, 1240 and 1660 nm are found to be useful for discriminating different glacier features. Limitations in hyperspectral remote sensing such as availability of imaging data, rugged topography and further research issues such as multi-sensor mapping and data fusion, multiangle measurements, 3D adjacency effect and improved algorithms for quantitative retrieval of contaminants are identified.Keywords

A critical element in seismic hazard estimation is the ground motion prediction equation (GMPE) which relates expected seismic intensity at a point from an earthquake of a given magnitude and location. Presently available GMPEs for plate interface thrust earthquakes along the Himalayan arc suffer from limited number of strong motion recordings used in their derivation. In this study we use a larger dataset, including recordings from the 2015 Gorhka, Nepal earthquake (Mw 7.9) and some of its larger aftershocks, to derive GMPE for earthquakes along the Western Himalayan arc. The proposed GMPE should give more reliable estimation of ground motion parameters at hard sites along the arc and in Peninsular India, and at soft sites in the Indo-Gangetic Plains.Keywords

The family Annonaceae has Gondwanan affinity and is being reported from the Cambay Shale of Vastan Lignite Mine on the basis of well-preserved fruit (in counterpart), leaf and pollen grains. This finding is significant because it serves as yet another example of an angiosperm family found in South America and Africa that may have boarded the Indian raft when India was attached to Madagascar, reported on the basis of pollen from Kutch. The Vastan occurrences represent a continuous record from the Indian latest Cretaceous, through the Palaeocene, based on multiple vegetative entities. The well-preserved fruit is morphologically similar to Annona palustris L. At present the dispersal history of the family into India represents an origin in the Lower Cretaceous of North America with later dispersal to South America and Africa and then onto India, as it is recorded from the sedimentary beds associated with the Deccan Volcanics. Another angiosperm family, Dipterocarpaceae, is also found in Vastan, with a similar phytogeographic distribution.Keywords

Of late, the crop productivity levels in many irrigated command areas have plateaued or started declining rapidly due to the deterioration of soil health. Unscientific and excessive irrigation, growing crops not compatible with the soils and unscientific management of soils are the main causes for the present situation. Waterlogging, increased salinity/sodicity, nutrient imbalance, shrinking diversity of micro-flora and fauna have become major constraints limiting the choice of crop and crop productivity. We present a study on this issue from the Cauvery command area. Detailed cadastral-level survey taken up to study the status of soil and other resources occurring in Chikkarasinakere block of Mandya district, Karnataka during 2010 has brought out the alarming state of land degradation observed in the area. Nearly 59% of the area is suffering from various degrees of chemical and physical degradation. The situation becomes alarming because the area had well-drained red soils highly suitable for irrigated agriculture when irrigation was introduced during 1930s. The process of degradation will accelerate if appropriate interventions/investments are not undertaken on priority. Continuation of present management practices can rapidly damage the soil health. As the command area is one of the important rice bowls of Karnataka, there is an urgent need to reverse the process of degradation by adopting site-specific interventions as indicated in the study. The present study reveals that the Cauvery command are in Karnataka is losing Rs 1000 crores every year due to this problem.Keywords

The present study documents the biological properties of the black soil region (BSR) of India in terms of culturable microbial population. Besides surface microbial population, subsurface population of individual soil horizons is described to improve the soil information system. An effort has been made to study the depth-wise distribution and factors (bioclimates, cropping systems, land use, management practices and soil properties) influencing the microbial population in the soils of the selected benchmark spots representing different agro-ecological sub-regions of BSR. The microbial population declined with depth and maximum activity was recorded within 0-30 cm soil depth. The average microbial population (log10 cfu g-1) in different bioclimates is in decreasing order of SHm > SHd > Sad > arid. Within cropping systems, legumebased system recorded higher microbial population (6.12 log10 cfu g-1) followed by cereal-based system (6.09 log10 cfu g-1). The mean microbial population in different cropping systems in decreasing order is legume > cereal > sugarcane > cotton. Significantly higher (P < 0.05) microbial population has been recorded in high management (6.20 log10 cfu g-1) and irrigated agrosystems (6.33 log10 cfu g-1) compared to low management (6.12 log10 cfu g-1) and rainfed agrosystems (6.17 log10 cfu g-1). The pooled analysis of data inclusive of bioclimates, cropping systems, land use, management practices, and edaphic factors indicates that microbial population is positively influenced by clay, fine clay, water content, electrical conductivity, organic carbon, cation exchange capacity and base saturation, whereas bulk density, pH, calcium carbonate and exchangeable magnesium percentage have a negative effect on the microbial population.Keywords

Crop simulation models have emerged as powerful tools for estimating yield gaps, forecasting production of agricultural crops and analysing the impact of climate change. In this study, the genetic coefficients for Bt hybrids established from field experiments were used in the InfoCrop-cotton model, which was calibrated and validated earlier to simulate the cotton production under different agro-climatic conditions. The model simulated results for Bt hybrids were satisfactory with an R2 value of 0.55 (n = 22), d value of 0.85 and a ischolar_main mean square error of 277 kg ha-1, which was 11.2% of the mean observed. Relative yield index (RYI) defined as the ratio between simulated rainfed (water-limited) yield to potential yield, was identified as a robust land quality index for rainfed cotton. RYI was derived for 16 representative benchmark (BM) locations of the black soil region from long-term simulation results of InfoCrop-cotton model (based on 11-40 years of weather data). The model could satisfactorily capture subtle differences in soil variables and weather patterns prevalent in the BM locations spread over 16 agro-ecological sub-regions (AESRs) resulting in a wide range of mean simulated rainfed cotton yields (482-4393 kg ha-1). The BM soils were ranked for their suitability for cotton cultivation based on RYI. The RYI of black soils (vertisols) ranged from 0.07 in Nimone to 0.80 in Panjari representing AESR (6.1) and AESR (10.2) respectively, suggesting that Panjri soils are better suited for rainfed cotton.Keywords

Advance wide field sensor (AWiFS) data of RESOURCESAT-1 and 2 satellites of IRS series were used to produce snow cover products at 10-day interval from 2004 to 2012 covering October to June of consecutive years for Alaknanda, Bhagirathi and Yamuna sub-basins of Ganga basin in the Himalayan region. The snow products were generated using Normalized Difference Snow Index (NDSI) at a spatial resolution of 56 m using green (B2) and SWIR (B5) channels of AWiFS sensor. Minimum and maximum snow cover was found to be 998, 669, 141 sq. km, and 7874, 5876, 3068 sq. km for Alaknanda, Bhagirathi and Yamuna sub-basins respectively. The areal extent of snow was higher than the mean during the years 2004-2005, 2007-2008 and 2011-2012 for all sub-basins. Mean of monthly fluctuations between maximum and minimum snow cover were recorded as 3105, 2305, 1235 sq. km corresponding to variation in snow line altitude of 1613, 1770, 1440 m respectively. A subtle increase in the snow cover has been observed in these three sub-basins during 2004-2012. The results matched well with the variations in temperature taken from nearby ground weather stations. Snow cover products were analysed to understand spatio-temporal variability of accumulation and ablation of snow in the three sub-basins. Monthly fluctuations in snow cover were high during accumulation period than in ablation. This work also attributes in generation of long-term database which will be useful for understanding climatic variations over Himalayan region.Keywords

Heat stress is a condition that is caused by worker over-exposure to the high temperature work environments often found in outdoor agriculture operations. Wet bulb globe temperature (WBGT) is a measure of heat stress especially when it is above 27°C. Considering the range of temperatures prevalent in the Rajasthan state of India during the months of May and June, agricultural operations during these months and the associated heat stress on the agricultural workers, this study was designed to ascertain the effect of WBGT on physiological cost of operation for agricultural workers. Southern Rajasthan was selected to conduct this study. Different WBGT of 28°C, 29°C, 30°C, 31°C and 32°C were selected for this study. The study conducted on twelve farm workers reveals that WBGT induces heat stress on the bodies of workers. The resting, working and delta heart rates and resting and working oxygen consumption rates of workers increased with increase of WBGT from 28°C to 32°C. The resting hear rate, working heart rate and ΔHR was found increasing linearly with wet Bulb globe temperature with higher correlation. Resting and working OCR were also having increasing linear relationship with wet bulb globe temperature.Keywords

In this paper the effect of spiroid winglet on aerodynamic efficiency was investigated. A sweptback and tapered wing with NACA 0015 airfoil section was considered as base geometry. Above wing is modified by providing spiroid winglet at the tip of wing. Velocity of 35 m/s was taken to simulate this. CFD code was use to carry out the computation. The simulated results were compared with experimental result to validate the CFD code. In this process tangential velocity, lift coefficient and drag coefficient were computed initially. The simulations obtained from the CFD code show a very good agreement with the experimental results. The aerodynamics parameters were calculated at different geometric angle of attack (4°, 8°, 12° and 16°). The numerical results were compared with the result of base line model to find out the effect of spiroid winglet. It was observed the drag is reduced by using spiroid winglet.Keywords

This paper aims to review the developments in the bioadhesive drug delivery systems to provide basic principles to the young scientists, which will be useful to circumvent the difficulties associated with the formulation design. Bioadhesion can be obtained by the building of either non-specific interactions with the mucosal surface, which are driven by the physicochemical properties of the particles and the surfaces, or specific interactions when a ligand attached to the particle is used for the recognition and attachment to a specific site at the mucosal surface. Starting with a review of the oral mucosa, mechanism of drug permeation, and characteristics of the desired polymers, this article then proceeds to cover the theories behind the adhesion of bioadhesive polymers to the mucosal epithelium. The primary goal of bioadhesive controlled drug delivery is to localize a delivery device within the body to enhance the drug absorption process in a site-specific manner. This article reviews desirable properties of bioadhesive polymers and the latest advancement in the field.

Heavy rainfall and hailstorm events occurred in major wheat-growing areas of India during February and March 2015 causing large-scale damages to the crop. An attempt was made to assess the impact of hailstorms in the states of Punjab, Haryana, Uttar Pradesh (UP), Rajasthan and Madhya Pradesh (MP) using remote sensing data. Multi-year remote sensing data from Resourcesat 2 AWiFS was used for the purpose. Wheat crop map, generated by the operational FASAL project, was used in the study. Normalized difference vegetation index (NDVI) deviation images were generated from the NDVI images of a similar period in 2014 and 2015. This was combined with the gridded data of cumulative rainfall during the period. The logical modelling approach was used for damage classification into normal, mild, moderate and severe. It was found that the northern and southern districts in Haryana were severely affected due to rainfall/ hailstorm. Eastern Rajasthan and western MP were also highly affected. Western UP was mildly affected. Crop cutting experiments (CCE) were carried out in two districts of MP. The CCE data showed that the affected fields had 7% lower yield than the unaffected fields. Empirical yield model was developed between wheat yield and NDVI using CCE data. This model was used to compute the loss in state-level wheat production. This showed that there was a reduction of 8.4% in national wheat production. The production loss estimated through this method matched with the Government estimates.Keywords

The findings of tourism statistics reveals that both domestic and foreign tourism are on a robust growth path in India. This growth opens up doors for substantial increase in infrastructure, including air-road, rail connectivity as well as hotels and restaurants. This growth has resulted in increased demand of manpower requirement in the field, thus resulting in more institution being established in the area of Tourism and Hospitality education. Within the context of the hospitality and tourism educational environment in Garhwal and the Kumaun region of Uttarakhand, this paper provides a comparative analysis of the preferred learning styles of students studying hospitality and tourism programmes. Specifically, it compares the learning styles of students studying in two regions of Uttarakhand depending on the year level of study and as such it highlights the learning style preferences displayed by students at different stages of their educational experience. The paper concludes with a discussion regarding the importance of recognising the potential changes in learning style preferences as student's progress in their studies. The paper further concludes with discussion regarding the implications of such changes for academic staff.Keywords

Soil salinity poses a serious threat for sustainable agricultural production. Out of 6.73 million ha salt affected soils in India, nearly 3.8 million ha is occupied by sodiclands, primarily spread in the Indo-Gangetic alluvial plains in the states of Haryana, Punjab, Uttar Pradesh and parts of Bihar and Rajasthan. In order to utilize these lands, Government of Uttar Pradesh through Uttar Pradesh Bhumi Sudhar Nigam, has been executing a project for reclamation of about 0.24 million ha of sodicland in seventeen districts of the state. Remote Sensing Applications Centre, Uttar Pradesh has been assigned the responsibility of identification and mapping of sodiclands at village level for reclamation and thereafter monitoring land use changes in reclaimed sodic plots in third/fourth year of reclamation. To assess the sustainability of reclamation after three/four years, randomly selected five villages reclaimed in the year 2000, studied for land use/land cover changes using IRS-1D LISS-III and PAN merged satellite data of Rabi (winter) season. The study reveals that 86 per cent of the earlier barren sodic plots were under crop. In the case of single and double cropped sodic plots, 97 per cent were under crop in third/fourth year after reclamation. The results thus indicate the sustainability of sodicland reclamation taken up under the project.Keywords

Rajasthan state is in west region of India. Maximum temperatures rise sharply exceeding 45° C by the end of May and early June resulting in harsh summers in the state. Heat stress is a condition that is caused by worker over-exposure to the high temperature work environments often found in outdoor agriculture operations. Wet Bulb Globe Temperature (WBGT) is a measure of heat stress. Considering the range of temperatures prevalent in the Rajasthan state during the months of May and June, agricultural operations during these months and the associated heat stress on the agricultural workers, this study was designed to ascertain the effect of WBGT on body thermal responses of agricultural workers. Southern Rajasthan was selected to conduct this study. The study was conducted on 12 farm workers. Different WBGT of 28°C, 29°C, 30°C, 31°C and 32°C were selected for this study. Thermal parameters included head, forehead and oral temperature. Forehead temperature was observed to decrease with an increase in WBGT. Heavy sweating was observed at high WBGT and this resulted in the decrease in skin and forehead temperature. Oral and head temperature was observed to increase with increase in WBGT. Since oral temperature is also considered to be the core temperature of body, it increased with increase in WBGT. Head absorbs the direct solar radiations and hence, its temperature increased with increase in WBGT.Keywords

Hypothyroidism has been associated with various neuropsychological issues that range from general mental dysfunction to specific cognitive domains such as memory, working memory, attention, visuospatial functions and language. These neuropsychological issues or deficits are found, in some cases, reversible while in some cases permanent, the current article reviewed various studies which have taken up these issues. The article starts with a brief introduction which throws light on endocrinological underpinnings of the thyroid gland with a brief reference to symptoms, pathophysiology, and epidemiology of thyroid hypo-function. Later, the article gives an overview of the prevalent research methodology used in this area of research. Further, the article discusses various types of neurocognitive deficits present in thyroid hypo-function followed by a discussion on their reversibility pattern. Following this, the article discusses the impact of thyroid hormone on brain and makes an attempt to delineate neuroanatomical correlates of thyroid hypo-function and neurocognitive deficits. Lastly, the article discusses how mood can be a potential confounder while establishing an association between neurocognitive deficits and thyroid hypo-function. The article concludes by discussing various limitations seen in the studies reviewed and identifies prospective areas for further research.Keywords

In order to access the genetic diversity, twenty five diverse strains of barley were subjected to D2 statistics for nine quantitative traits viz. days to flowering, plant height, number of productive tillers per plant, ear length, number of grains per ear, grain weight per ear, 1000 grain weight, seed hardness and grain yield per plant. Genotypes were grouped into five clusters. Cluster I and II were most divergent. The genotypes of these three clusters may be used for hybridization programme. 1000 grain weight and plant height contributed more towards total divergence.Keywords

Density and ultrasonic velocity of binary liquid mixture of two nuclear extractants:di-(2-ethylhexyl) phosphoric acids (D2EHPA) and methyl isobutyl ketone (MIBK) have been experimentally measured over entire range of composition at 2 MHz and temperature 303.15K. The experimental results are employed to compute acoustic parameters viz. acoustic impedance, isentropic compressibility, intermolecular free length and relaxation strength in the entire range of D2EHPA molefraction. The non-linear increase of ultrasonic velocity, density, acoustic impedance and decrease of isentropic compressibility, intermolecular free length, relaxation strength with mole fraction of D2EHPA indicates the presence of strong interaction between the components of liquids. The theoretical values of ultrasonic velocity have been calculated using various empirical relations and models, viz. Impedance dependence relation, Nomoto's relation, Rao's specific sound velocity relation, Danusso model, Junjie's relation,Van Dael-Vangeel's ideal mixing relation, Schaaff's collision factor theory and are compared with the corresponding experimental data by applying ischolar_main mean square deviation relative (RMSDr). A comparison of theoretical values of ultrasonic velocity with those obtained experimentally reveals that Nomoto's relation predicts the data reasonably well.Keywords

The extent of snow cover on the earth is considered an important parameter for numerous climatological and hydrological applications. Snow cover dynamics in mountainous regions is a vital input for energy balance, glacier mass balance, climate change and snowmelt runoff modelling. There have been global efforts for monitoring of snow cover of earth at varying spatial and temporal scales by generation of snow products. Among these, one of the high temporal and spatial resolution datasets has been generated using advanced wide field sensor data for Western and West-Central Himalayan region at the Space Applications Centre, Ahmedabad. This is done using an algorithm developed based on normalized difference snow index. This paper discusses the trends of snow cover from 2004 to 2014 based on an input of approximately 12,600 snow cover products at sub-basin scale in Indus, Chenab, Satluj and Ganga basins. Analysis of snow cover shows high variability during accumulation than in ablation period. A subtle increase in snow cover was observed in all basins during 2004–2014.Keywords

Soil fertility has direct implications on the agricultural production scenarios of a region. Surface soil samples at 1 km grid were collected to assess the fertility status of Lakhimpur district (Assam) in North East India. Fertility parameters like soil organic carbon, available nitrogen, phosphorus, potassium, iron, manganese, zinc and copper were determined using standard analytical procedure. Spatial distribution maps of the soil parameters were generated using regularized spline method in ArcGIS 10.0. The average soil organic carbon content was 1.05% and the maximum area was under high availability status (78%). In the case of nitrogen, 57% of the area was under low availability status. In the case of available potassium and phosphorus, the areas under low availability status were 48% and 49% respectively. But for micronutrients, in general, the availability status was high except for zinc, which indicated that 40% of the area was under low availability. A methodology was developed to integrate the individual nutrient layers using a set of decision rules to identify the multinutrient deficient zones. The integrated map showed that 24% of the area had multiple nutrient deficiencies and fell under high priority zone that warrant immediate nutrient management interventions to mitigate the situation.Keywords

Onion (Allium cepa) is one of the most important bulb crops in India, which plays a major role in supplementing the Income of small and marginal farmers of different district in Madhya Pradesh. One of the major constraints of Kharif onion farming is poor nursery and low productivity due to non adoption of recommended package of practices and improved verities. To replace this anomaly, National Horticultural Research and Development Foundation, Indore (M.P.) had conducted TDTD (Technology dissemination through demonstration) under National Horticulture Mission, Govt. of India, at adopted farmers’ fields. Cultivation practices comprised under TDTD viz., use of improved variety/season specific, nursery raising, soil/seed treatment, transplanting, fertilizer application and control of purple blotch disease, showed that percentage increase in the yield of onion ranged from 31.07% to 36.40% over local check during the course of study from 2012-13 to 2016-17. The technology gap of 6.2 q/ha during 2016-17 from 27.6 q/ha at the initial stage of study (2012-13) shows the gap in demonstration yield over potential yield, but the above gap reduced subsequently in the following years.Keywords

Analysis of variability carried out for ten characters in sixteen diverse genotypes of nigella (Nigella sativa L.) revealed high genotypic and phenotypic co-efficient of variations for secondary branches per plant, number of grains per fruit, number of fruits per plant, length of fruit (cm) and width of fruit (cm). Heritability estimates were high for number of grains per fruit (0.86), number of fruit per plant (0.78), length of fruit (0.64), days to maturity (0.59), number of secondary branches per plant (0.56) and yield per plant (0.47). Higher genetic advance as percentage of mean was recorded for number of grains per fruit (46.11%), number of secondary branches per plant (43.99%), number of fruits per plant (39.65%), yield per plant (24.49%), length of fruit (24.12%) and indicating additive gene effect. Quantitative traits like days to maturity, number of secondary branches per plant, number of grains per fruit and number of grains per fruit exhibited wide range of variability (134.33-143.00) maximum genotypic co-efficient of variability (29.53), maximum phenotypic co-efficient of variability (22.18), broad sense heritability (0.86) and gene gain (46.11).Keywords

In this study, we assess quantitative soil loss in the Himalayan ecosystem of Uttarakhand, India using universal soil loss equation and geographic information system. The analysis shows that about 359,000 (6.71%), 473,000 (8.84%) and 1,750,000 ha (32.72%) area is under moderately severe (15–20 tonne ha–1 year–1), severe (20–40 tonne ha–1 year–1) and very severe (40–80 tonne ha–1 year–1) soil loss respectively. It clearly indicates that about 48.3% area of the state is above the tolerance limit of 11.2 tonne ha–1 year–1 of soil loss. This explains the need to undertake appropriate soil and water conservation measures to mitigate the topsoil loss in this fragile Himalayan ecosystem. Based on the degree of severity of soil loss, appropriate soil and water conservation measures need to be adopted on priority basis. The agriculture practices should be diversified with farm-forestry, agro-horticulture and/or agro-forestry to minimize soil loss in cultivated areas of the state. Such conservation programmes help mitigate accelerated soil erosion, restore the fragile ecosystems and generate employment opportunities for the needy.Keywords

Desertification is the transformation of productive land into a non-productive one due to poor resource management, and unfavourable biophysical and economical factors. Periodical assessment of desertification status is imperative for a suitable comprehensive and combating plan. In the present study, desertification status maps of Andhra Pradesh (AP), Karnataka and Telangana in South India have been prepared using remote sensing data for two time-frames (2003– 2005 and 2011–2013) and change detection analysis has been carried out. The results reveal that 14.35%, 36.24% and 31.40% of the total geographical area in Andhra Pradesh, Karnataka and Telangana were affected by desertification processes respectively, in 2011–2013. Among the desertification processes, vegetal degradation contributes 7.27% of total area in AP, followed by water erosion (4.93%) and waterlogging (0.83%), whereas in Karnataka water erosion (26.29%) is dominant followed by vegetal degradation (8.93%) and salinization (0.45%). Change detection analysis shows that desertification processes of AP and Karnataka have increased by 0.19% and 0.05% respectively, whereas in Telangana it has decreased by about 0.52% from 2003 to 2005 data. The present database will help the scientists, planners and stakeholders to prepare appropriate land reclamation measures to control the increasing trend of desertification.Keywords

Land resource inventory for site-specific planning and development of watersheds on scientific basis under Sujala-III project sponsored by the Watershed Development Department of Karnataka and funded by the World Bank is being implemented in 11 districts covering 9.66 lakh ha across 2531 microwatersheds benefiting 7.02 lakh households in the state. The analysis and interpretation of the spatial and non-spatial database generated so far in 1600 microwatersheds covering 5 lakh ha has revealed that most of the watersheds suffer from major problems. In many watersheds, soil erosion and alkalinity affected even up to 75% of the watershed area, thus reducing the production potential and crop choices. The soils are either moderately or highly suited for growing most of the agricultural and horticultural crops. By interfacing land resource data with RS, GIS and GPS, different management scenarios were analysed to arrive at the best management alternatives (optimum land use plans) that would be most suitable. This data handling system will be useful for making land use decisions and providing proactive advice to farmers on a real time basis protecting the health of natural resources.Keywords

Present study focuses on the utilization of Earth observation satellite-04 (EOS-04) synthetic aperture radar (SAR) data for maintaining the continuity of the first Indian radar imaging satellite (RISAT)-1 SAR derived products along with exploring the potential of capability of the improved sensor over mountain and polar cryospheric region. Backscattering coefficient (s 0) of various snow and ice features over mountain and polar cryosphere have been analysed to understand the interaction mechanism using C-band SAR data. EOS-04 is able to pick up the spatio-temporal variability of SAR backscatters over accumulation and ablation zone of the glacier due to melt-freeze cycles, and observations were in accordance with variation in elevations over the glacier surface. When analysed for Drang-Drung glacier, wet snow zone was found to be prominently centered around 5500 m elevation zone, having sigma-naught backscatter lower than –10 dB in the ablation months, whereas percolation zone was observed at more than 6000 m elevation with higher sigma-naught backscatter of around –4 dB and above as winter started setting in. EOS-04 also showed the potential to classify various polar ice features based on backscattering signature using HH (H, horizontal) (s 0), HV (V, vertical) (s 0) and normalized difference polarization ratio index (NDPRI) respectively. EOS-04 data have been used to implement approaches to retrieve wet snow cover and set up of Weather Research and Forecasting Model Hydrological Modelling System (WRF hydro) model for snow melt runoff studies, interaction mechanism of snow and ice, snow/ice facies extraction, ice shelf monitoring, sea ice properties and sea ice advisory for Indian scientific expedition to Antarctica. Enrichment of EOS-04 data, suitable for cryosphere studies, will be employed to retrieve parameters such as snowpack properties, elevation, ice surface velocities over mountain and polar region, and to further improve comprehensive understanding on regional and global frozen ice dynamics.Keywords

Theoretical computation of sound velocity and their bulk modulus for many lubricating oils having various applications in machinery and daily lives at different ranges of temperature over the entire concentration range has been done from the measured data of Mia and Ohno. An attempt has also been envisaged to predict the molecular interactions and molecular structure involved therein and also to establish relationship among sound velocity, surface tension, adiabatic compressibility and their bulk modulus. It is found that theoretical results for sound velocity agreed well within the experimental precision when compared with experimental data. These properties are helpful in predicting the group of the lubricating oil of which they belong.

Identification and delineation of potential areas for different crops, both at country and state level by using available legacy data assumes importance, in order to preserve and conserve these areas to feed the increasing population and future generations. In this direction, a new integrated approach has been developed to identify potential areas for different crops and the same has been validated. Identifying and delineating commodity specific areas/zones, would help in enhancing the productivity and profitability and framing of land use policies.Keywords

Snow and urban land cover are important due to their role in hydrological management and utility, climate response, social aspects and economic viability, along with influencing the Earth’s environment at local, regional and global scale. Hyperspectral data enable identification, characterization and retrieval of these land-cover features based on physical and chemical properties of compositional materials. AVIRISNG hyperspectral airborne data, with synchronous ground observations using field spectroradiometer and collateral instruments, were collected over two widely varied land-cover types, viz. a relatively homogenous area covered by snow in the extreme cold environment of the Himalaya (Bhaga sub-basin, Himachal Pradesh), and a completely heterogeneous urban area of a metropolitan city (Ahmedabad, Gujarat).
AVIRIS-NG airborne data were analysed to understand the effect of terrain parameters such as slope and aspect on snow reflectance. Snow grain index using visible and near-infrared (VNIR) bands and absorption peak in the near-infrared (NIR) were used to retrieve grain size in parts of the Himalayan region. A radiative transfer model was used to understand the grain size variability and its effect on absorption peak in NIR. Continuum removal was performed for snow spectral observations obtained from airborne, modelled and field platforms to estimate band depth at 1030 nm. Grain size was observed to vary with altitude from 100 to 500 μm using AVIRIS-NG image. In the urban area, the data also separated pervious and impervious surface cover using spectral unmixing technique, identified several urban features over multispectral data such as buildings with red tiled roofs, metallic surfaces and tarpaulin sheets using the material spectral profiles. Two single-frame superresolution methods namely sparse regression and natural prior (SRP), and gradient profile prior (GPP) were applied on AVIRIS-NG data for the mixed environment around Kankaria Lake in the city of Ahmedabad, which revealed that SRP method was better than GPP, and affirmed by eight indices. Preliminary analysis of AVIRIS-NG imaging over snow-covered areas and densely populated cities indicated utility of future spaceborne hyperspectral missions, particularly for hydrological and climatological applications in such diverse environments.

Natural forests and managed plantations constitute the largest land-use systems in the humid tropics of southwestern parts of Peninsular India comprising the Western Ghats and coastal plain. Soils therein are naturally acidic and the acidity is enhanced in managed land-use systems through inputs of chemical fertilizers. Plant nutrient deficiencies and mineral toxicities constrain crop production in acid soils. Surface soil and subsoil acidity in forest, coffee, rubber and coconut land-use systems was evaluated. The spatial pattern of surface soil and subsoil acidity pointed to low intensity of acidification in Malnad region of Karnataka, moderate acidity in northern Kerala and strong acidity in southern Kerala. Among the land-use systems studied, soils under natural forests and coffee plantations were only slightly acidic in surface soil and subsoil, whereas rubber- and coconut-growing soils were strongly acidic. Both natural and managed land-use systems, however, had strongly acid reaction in surface soil and subsoil in southern Kerala. Biomass production and crop yield are constrained in strongly acid soil by toxic levels of aluminium (Al) on soil exchange complex (>0.5 cmol (+) kg–1 soil) and depletion of basic cations of calcium, magnesium and potassium (base saturation less than 50% or Al saturation more than 50%). Surface soil acidity can be ameliorated by incorporating liming materials into surface soils. In case of subsoil acidity gypsum too should be incorporated. Under humid climate partial solubility of gypsum permits movement of calcium into the subsoil layers, wherein calcium replaces the aluminium on exchange complex and sulphate radical precipitates the aluminium by formation of aluminium sulphate.Keywords

Soil hydraulic properties are important for irrigation scheduling and proper land-use planning. Field capacity, permanent wilting point and infiltration rate are the three vital hydraulic properties which determine the availability and retention of water for crop growth. These properties are difficult to measure and time-consuming, but can be easily predicted from the available information like soil texture, bulk density, organic carbon content, etc. through pedotransfer functions (PTFs). PTFs were developed for field capacity and permanent wilting point for two different regions of Karnataka, viz. Northern Karnataka Plateau (512 soil samples) and Southern Karnataka Plateau (228 soil samples), separately. PTF for infiltration rate was developed using 100 soil samples for the entire Karnataka. Cross-validation techniques were used to validate the PTFs, and the results are satisfactory with low RMSE and higher R2. The developed PTFs are useful in determining soil hydraulic properties of the semi-arid regions of southern India.Keywords

The spotted pod borer, Maruca vitrata(Fab.) causes significant damage by attacking pods in cowpea. The aim of this study was to evaluate the field efficacy of new generation insecticides against spotted pod borer. Field experiments were conducted at Regional Research Station, Nasik (Maharashtra) on cowpea during Kharif,2009 and 2010. Among the new generations tested, flubendiamide 20 WG @ 1.0 g/l (4.79%) was observed significantly higher, in reducing the damage caused by the spotted pod borer in cowpea, on number basis followed by indoxacarb 14.5SC @ 0.5 ml/l (7.99%) and spinosad 45 SC @ 0.3 ml/l (8.70%). The highest marketable yield (91.49 q/ha) was recorded in flubendiamide 20 WG @ 1.0 g/l followed by spinosad 45 SC @ 0.3 ml/l (91.39 q/ha). However, the maximum cost benefit ratio (1:3.2) was recorded in thiodicarb 75 WP @ 1 g/l followed by indoxacarb 14.5 SC @ 0.5 ml/l (1:2.3), spinosad 45 SC @ 0.3 ml/l (1:1.9), emamectin benzoate 5 SG @ 0.5 g/l (1:1.3), flubendiamide 20 WG @ 1.0 g/l (1:1.1). On the basis of efficacy, flubendiamide 20 WG @ 1.0 g/l was observed to be very effective against Maruca vitratain cowpea followed by indoxacarb 14.5 SC @ 0.5 ml/l and spinosad 45 SC @ 0.3 ml/l.Keywords

The study was carried out to know the gap between improved packages of practices in gram crop. Frontline demonstration on gram varieties J.G.16, JAKI 92-18 and J.G. 130 were conducted at farmer’s field in the adopted village of Krishi Vigyan Kendra, Lahar Bhind (M.P.) during the years 2010-11 to 2014-15. The average yield of J.G. 16 variety was 18.07 q/ha. J.G. 16 has given 20.4 q/ha. Highest yield during the year under frontline demonstration while local varieties gave 16.61 q/ha average yield during the year. The variety JAKI -9218 was demonstrated during 2011-12 and 2012-13 gave average yield at the farmers field 17.32 q/ha and 15.99 q/ ha, respectively. While variety conducted farmers practice gave average yield 13.62 q/ha and 13.52 during the years, respectively. The variety was given 18.50 q/ha. Highest yield under FLD, while farmers practice given highest yield 13.90 q/ha. The variety conducted under front line demonstrated was gave 27.16 per cent and 18.26 per cent higher yield over farmers practices during 2011-2012 and 2012-13, respectively. The average B.C. ratio of demonstrated technology was 1:180. J.G. 130 variety of gram tested at farmers field during 2012-13 and gave average yield 17.56 q/ha. While it was 13.1q/ha. in farmers practice. 34.04 per cent increased yield was recorded over farmer’s practices. The variety JG 130 also demonstrated in farmers field under frontline demonstration during 2013-14 and 2014 -15 in 10.40 ha land on 26 farmers field, this variety during the years could not sown its performance due to rainfall and hailstorm during flowering to maturity. The average yield during the years (2013-14 and 2014 -15) was 6.13 and 2.53 q / while it had been seen in case of farmers practice 3.93 q/ha and 2.50 q/ha, respectively. Sixty four demonstration have been conducted during 2010-11 to 2014-15 in 25.80 ha of land. It could be said the yield performance of variety under improved package of practices not only in favour of increased yield but also economic condition of the farmers of the district.Keywords

Densities, refractive indices and speeds of sound and their excess properties for 1-butyl-3-methylimidazolium tetrafluoroborate [Bmim][BF4] with 1-pentanol over the entire range of mole fraction are reported at temperatures ranging from 298.15 K to 313.15 K and atmospheric pressure. Isentropic and excess isentropic compressibility for ionic liquids with 1-alcohols were calculated from the experimental results. The excess values are fitted to the Redlich-Kister polynomial equation to estimate the binary coefficients and standard error between the experimental and calculated values. The measured speeds of sound were compared to the values obtained from Schaaffs' collision factor theory, Jacobson's intermolecular free length theory of solutions and Nomoto's relation. In addition, the experimentally obtained refractive indices were compared to the calculated values using Lorentz- Lorenz, Dale-Gladstone and Eykman mixing rules. The theoretical results obtained from these relations fairly agrees within the experimental precision. Further, the molecular interactions involved in IL binary mixture system were studied.Keywords

Pearl millet is an important cereal crop grown for grain and fodder in arid and semi-arid regions of India. Pyricularia grisea (teleomorph: Magnaporthe grisea) is known to cause devastating foliar blast disease leading to reduction in grain and fodder yields in pearl millet. Internal transcribed spacer sequencing of ribosomal DNA revealed that the foliar blast of pearl millet in western arid Rajasthan, India, is caused by Pyricularia pennisetigena. Multiple sequence alignment validated that the reference sequence of P. pennisetigena from USA, aligned well with that of our sequence of P. pennisetigena. Phylogram clearly delineated P. grisea and P. penniseticola as phylogenetically separate species of Pyricularia compared to P. pennisetigena. Therefore concerted efforts are needed to develop resistant varieties and hybrids in pearl millet against P. pennisetigena in future plant breeding programmes, particularly for western arid Rajasthan. In addition, isolate CZPMP-17, molecularly identified as Colletotrichum sublioneola isolated from P. glaucum causing foliar disease is shown to be a pathogen of pearl millet.Keywords

The present study assessed the effect of improved agricultural technologies disseminated under the ambitious Farmer FIRST Programme on production costs of major crops in Bundelkhand region, Uttar Pradesh, India. The findings show that the average real cost during 2017–18 to 2020–21 declined, leading to an increase in the net return to cost ratio from farming. Technological interventions at the farmer’s field resulted in a gradual decline in the share of seed, fertilizer and plant protection chemicals in the cost of cultivation. The price elasticity of factors, estimated by fitting the translog function, suggests that policies for controlling input price inflation, particularly wage rate, will be imperative in reducing the cost of farming. The results on the elasticity of technical substitution between labour and machinery highlight the need for devising suitable farm mechanization strategies which may be affordable in the small farm situation as well. The panel data estimate of negative cost elasticity of yield indicates that productivity growth plays a vital role in absorbing the increase in production costKeywords
