Sustainable and increased agricultural productivity emphasize judicious use of water and nutrients accompanied by other factors. This can be achieved by application of water and nutrients through drip fertigation, which is the most advanced and efficient practice of fertilizer application. It has to follow appropriate management strategies to get maximum benefit, which become easy through automatic operation system. Therefore, an automated drip fertigation system was installed in mango (Mangifera indica L.) and guava (Psidium guajava L.) orchards at the farm of Central Institute of Agricultural Engineering, Bhopal, Madhya Pradesh. Irrigation and fertilizers were provided to mango and guava as per crop water requirement and scheduling. The mean fruit yield of guava under automated drip fertigation system was found to be 10.29-13.07 tonnes/ha and increased by 27.03 per cent during the period from 2007-08 to 2009-10. It increased significantly from 15.6 per cent to 23.7 per cent over conventional system during the same period. The pulp content of guava varied between 95.4 - 95.5 per cent and was higher by 1.38-1.60 per cent as compared to conventional system. The mean fruit yield of mango was 8.00-12.80 tonnes/ha and increased to 60.0 per cent under automated drip fertigation. The mean fruit yield of mango significantly increased from 17.6 to 23.1per cent over conventional practices. The pulp content of mango under automated drip fertigation ranged between 74.5 to 74.6 per cent being 3.33-3.47 per cent higher than conventional system during the study period. Total cost of cultivation through automated drip fertigation varied from Rs.1,56,383- Rs.12,17,913 and Rs. 1,73, 775- Rs. 15,65,774 for guava and mango, respectively for one to 20 hectare area. The benefit cost ratio for mango and guava orchard reached 1.45 and 2.20 for 20 hectare area, respectively. This study indicated that automated drip fertigation system could be techno-economically feasible for use in 5-20 hectares of mango and 3-20 hectares of guava.Keywords

Worldwide 10-50 per cent of irrigated agriculture is facing problems of waterlogging and soil salinity which cause loss of around 1.5 million hectare land annually. The problems of alkalinity and salinity coupled with waterlogging affect about 7.3 million hectares land in India, which reduce agricultural productivity. At the same time agriculture is facing increase in water demand at 2.4 per cent annually during 2005 -2030 as well as reducing share of water due to competing demand from industry and urbanizations. Therefore, to fulfill food and nutritional security of nation on sustained basis, both salt affected soils and waters need to be managed using appropriate techniques. Techniques for controlling salinity that require relatively minor changes are more frequent irrigations, selection of more salt-tolerant crops, additional leaching, residue management, chemical amendments, pre-plant irrigation, bed forming and seed placement. These require significant changes in management such as, changing the irrigation method, altering the water supply, land-leveling, modifying the soil profile, and installing surface as well as subsurface drainage. Where possible, furrow planting may help in obtaining better stands and crop yields under saline conditions. Studies have shown that yield obtained by the drip method with saline water was almost equal to that produced when the high quality water was applied by this method. Therefore, improved agricultural production and water productivity on sustained basis could be realized by application of techniques to manage salt affected soils and waters.Keywords

The effect of bio-fertilizer was studied in banana accessions intensively collected from ICAR Research Complex for NEH Region, Mizoram Centre, Kolasib, Mizoram during 2009-2010. To assess the efficacy of different bio-fertilizer viz., Azospirillium, Azotobacter and phosphorus solubilizing bacteria (PSB) either alone or in combination was applied 20g per plant with recommended dose of FYM. The six treatments were arranged in a Randomized Block Design in three replications and spaced at 2.5 × 2.5 m in order to study its effect on growth, yield and quality attributing traits. All the characters were significantly increased except number of suckers and number of leaves due to application of each of the two-bio fertilizers either separately or in combination. Moreover in combination ofAzotobacter + PSB 20g per plant showed that more effective than either combination or in separately of another bio-fertilizers. This might be due to because biological nitrogen fixation depends appreciably on the available form of phosphorus. So the combined inoculation of nitrogen fixers and PSB may benefit the plant better (by providing both nitrogen as well as phosphorus) than either alone.Keywords

A new simple, accurate and reasonably sensitive spectrophotometric method is described for the determination of reserpine based on the oxidation with sodium metaperiodate in the presence of acetic acid and coupling with 3-methyl-2-benzo thiazolinone hydazone hydrochloride (MBTH) to form highly blue coloured product showing maximum absorbance at 630 nm. Beer's law is obeyed in the range 0.2-1.6 μg ml-1. The relative standard deviation was found to be less than 1%. The proposed method can be applied for the estimation of reserpine in tablets with no evidence of interference from excipients.Keywords

The distribution of the higher basidiomycetes of the Sibsagar district of Assam has been studies with the application of Poisson's probability distribution.
The fungi mostly occur in patches or pockets of podzolic soil formations having a rich forest cover, Agaricaceae occurring most commonly. The types of fungi were also classified as soil-inhabiting and wood-inhabiting, the former with sporophores submerged in the soil superficially.
The Poisson's probability distribution also explains the mode of distribution to certain extent provided the places of occurrence of these fungi are not disturbed markedly.

Buxar forms a district of Patna division in the Ganga Valley and is under intense cultivation and irrigation by an efficient sone canal system. In the present paper life-forms of 540 angiospermic species have been studied and the same have been compared with Raunkiaer's normal biological spectrum and other spectra of the adjoining regions of Ganga Valley. This reveals the dominance of therophytes which indicate that the phytoclimate of the district is therophytic. The area is devoid of its original natural vegetation and the dominance of therophytes is due to the introduction of weeds of cultivation.Full Text

The homworts, comprising a small, phylogenetically significant group of plants, are represented in India by 5 genera, viz. Anthoceros L. emend. Prosk., Folioceros Bharad. (Anthocerotaceae); Notothylas Sull. (Notothylaceae); Megaceros Campb. and Phaeoceros Prosk. (Phaeocerotaceae), 35 species and 2 subspecies. Anthocerotaceae and Phaeocerotaceae show greater manifestation in the Himalayas, whereas the Western ghats abound in maximum members of Notothylaceae. Fifty eight percent (or 21 species) of the total Indian homworts are endemic, of which only Anthoceros bharadwajii Udar et Asthana, A. erectux Kash. and Notothylas himalayensis Udar et Singh have an extended range of distribution in more than one bryogeographical territories. The high incidence of primitive Notothylas taxa coupled with the highest endemism encountered in the Western ghats makes this region Cradle ot the genus. The other phytogeographical elements discernible amongst Indian homworts are : Cosmopolitan (4), Disjuncts (4) and Eastern Asiatics (7). The rich and phytogeographically unique homwort flora of its own, notwithstanding, about 28% of the Indian anthocerotes could never be located again since their original collection. Certain biotic influences, on the other hand, are threatening a tew other species of their survival. The paper epitomizes the causes of threats and rarity of such taxa and discusses the strategies to salvage the situation.Full Text

Stratified random sampling with probability proportion to the size (PPS) is adopted for analyzing vegetation composition of all types. Vegetation cover type map derived using satellite remote sensing data have been considered as prime input for phytodiversity analysis of forest ecosystem. Geographic Information System (GIS) has been used to derive landscape indices such as fragmentation, porosity, patchiness, patch density, interspersion and juxtaposition, which depict landscape characteristics. Phytodiversity richness map generated for the Shiwalik hills of Punjab state is based on the disturbance index, terrain complexity, species richness, biological value and ecosystem uniqueness. The resultant maps highlight areas that are rich in phytodiversity. Forests of Shiwalik hills of Punjab state are moderately rich in some fragmented pockets. Deciduous forest showed high degree of richness (55.09% and 12.86% in high and very high categories respectively) followed by moist deciduous forest (17.92% in high and 16.19% in very high categories). Deciduous scrub shows least richness (13.96 % in high and 1.61 % in very high categories) as compared to pine forest (16.72% in high and 4.55% in very high categories). Phytosociological data collected from field sampling was analyzed to derive species richness, biodiversity value and importance value of various forest types.Full Text

The genus Calypogeia Raddi is represented in India by six species (Singh, 2001). All the six species are found in Eastern Himalaya with three species, C. aeruginosa Mitt., C. fissa (L.) Raddi and C. marginella Mitt., restricted to this region alone in Indian bryoflora. Of the remaining three, C. arguta Nees & Mont. is common to Eastern Himalaya, Central India, South India and the Andaman and Nicobar Islands; C. azurea Stotler & Crotz occurs in both Eastern and Western Himalaya and South India and C. lunata Mitt. is common to Eastern as well as Western Himalaya (Mitten, 1861; Chopra, 1943; Sharma & Srivastava, 1993; Singh & al., 2008). During the course of study on the liverworts and hornworts of Mehao Wildlife Sanctuary in Arunachal Pradesh, Eastern Himalaya, the authors came across an interesting species of the genus Calypogeia Raddi. Detailed morphotaxonomic study of the species and study of relevant literature (Bischler, 1962a, 1962b; Srivastava & Sharma, 1986; Sharma & Srivastava, 1993; Paton, 1999) revealed it to be a hitherto undescribed species of the genus. The same has been described and illustrated as C. udarii in the present communication.Full Text

The genus Lopholejeunea (Spruce) Schiffn. is globally represented by 30 species referable to three subgenera viz., subgenus Pholianthus B.M. Thiers & Gradst. (with a single species confined to Australia and New Zealand), subgenus Pteryganthus B.M. Thiers (with four species confined to East Africa) and subgenus Lopholejeunea (with 25 species distributed all over the tropics, 17 of which occur in Asia) (Zhu & Gradstein, 2005). In India Awasthi & al. (2000) and Singh & Nath (2004) recorded 11 species and two varieties distributed in Eastern Himalaya (8 taxa), Western Ghats (7 taxa), Western Himalaya, Central India and the Andaman & Nicobar Islands (one species each). However, Zhu and Gradstein (2005), who further grouped the Asiatic species of the subgenus Lopholejeunea into sections Lopholejeunea (with 9 species characterized by the apex of leaf lobule attached to the leaf lobe across 2-8 cells) and Eulophae Verd. (with 8 species characterized by the leaf lobule attached to the leaf lobe across a single cell), recognised only 5 species from the country viz., L. applanata (Reinw. & al.) Schiffn., L. eulopha (Taylor) Schiffh. [=L. nicobarica Steph.] and L. nigricans (Lindenb.) Schiffh. [=L. abortiva (Mitt.) Steph. var. abortiva, L. abortiva var. doliiformis U.S. Awasthi & al., L. javanica (Nees) Schiffn., L. kashyapii U.S. Awasthi & al., L. sikkimensis Steph. var. dentata U.S. Awasthi & al., L. sikkimensis Steph. var. sikkimensis] belonging to sect. Eulophae, and L. recurvata Mizut. and L. subfusca (Nees) Steph. [=L. nilgiriensis U.S. Awasthi & al. and L. indica Udar & U.S. Awasthi] belonging to sect. Lopholejeunea. Later S.K. Singh & D.K. Singh (2006) described a new variety, L. sikkimensis var. tenuicostata Sushil K.Singh & D.K. Singh from the Western Himalaya, whereas Singh and Nath (2006) described L. nongstoinii A.P.Singh & V. Nath from the Eastern Himalaya.
During recent studies on the epiphyllous liverworts of Eastern Himalaya, an interesting population of the genus, referable to sect. Lopholejeunea, was observed in West Siang district of Arunachal Pradesh, which on the basis of comparative evaluation of morphological characters of species hitherto known under this section merit the status of a new species.

The genus Ptilidium Nees was recorded for the first time from India by Mitten (1861), who described two species, viz. Ptilidium ciliare (L.) Hampe, and P. trichophyllum Mitt. [now treated under a separate genus as Blepharostoma trichophyllum (L.) Dumort.] based on the specimens collected by Sir J.D. Hooker from Sikkim. In the present state of our knowledge the genus is represented world over by three species, viz. P. ciliare (L.) Hampe, P. pulcherrimum (G. Weber) Vainio and P. californicum (Austin) Pearson (Stotler & Crandall-Stotler, 2005), of which only P. ciliare was known from India (Mitten, 1861; Chopra, 1943; Parihar & al., 1994; Singh & al., 2008). In a recent exploration in North Sikkim, some interesting corticolous specimens of the genus were collected with undifferentiated stem cells, 3-4(-5)-lobed leaves with the dorsal lobe 6, 10 cells wide at base and the dorsal sinus descending up to 2/3, 4/5 of leaf length, hence distinct from P. ciliare. A subsequent literature review (Macvicar, 1926; Schuster 1966; Paton, 1999) revealed it to be Ptilidium pulcherrimum (G. Weber) Vainio, earlier known from China, Japan, Europe and North America. The same has been described and illustrated here to facilitate its easy identification in Indian flora.Full Text

Tuyamaella S. Hatt, a small genus represented by six species and two varieties, is distributed in Asiatic and oceanic region (Zhu & So, 2000a, 2001). Of these, one species and two varieties are endemic to their respective countries, viz. T. borneensis Tixier (Indonesia), T. molischii (Schiffn.) S. Hatt. var. brevistipa P.C. Wu & P.J. Lin (China), T. molischii (Schiffn.) S.Hatt. var. taiwanensis R.L. Zhu & M.L. So (Taiwan), T. hattorii Tixier is restricted to Vietnam and Laos, T. jackii (Steph.) Tixier is restricted to Vietnam and Kampuchea. The remaining three species show an extended range of distribution, viz. T. angulistipa (Steph.) R.M. Schust. & Kachroo (China, Indonesia, Malaysia, Vietnam, Kampuchea, Papua New Guinea), T. molischii (Schiffn.) S. Hatt. var. molischii (China, Japan, Malaysia, Vietnam) and T. serratistipa S. Hatt. (Indonesia, Papua New Guinea, Philippines, Malaysia, New Caledonia) (Tixier, 1973; Zhu & So, 1998, 2000a, b, 2001). The earlier record of T. angulistipa (= Pycnolejeunea angulistipa Steph.) from India by Chopra (1943) based on Stephani's (1914) report from India Orientalis (Perak) appears to be erroneous. Perhaps for this reason the genus does not find any mention in the recent review on Indian Lejeuneaceae in India (Asthana, 2007).
During the course of studies on the epiphyllous liverworts of Eastern Himalaya, the authors came across an interesting collection belonging to family Lejeuneaceae from West Siang district of Arunachal Pradesh which differed from all the known taxa of the family from India. Subsequent morpho-taxonomic studies on the plants followed by review of relevant literature (Tixier, 1973; Zhu & So, 1998, 2000a, b, 2001) revealed them to be Tuyamaella serratistipa S. Hatt., a species so far known from Indonesia, Papua New Guinea, Philippines, Malaysia and New Caledonia (Zhu & So, 1998, 2000b).

The maximum callus formation (20.3%) was observed in treatment BAP 8 mgl-1 while the minimum (4.6%) was noted under control. With the combination of BAP and BA, the maximum callus formation ( 27.0%) was recorded under BAP 8 mgl-1 + BA 4 mgl-1 ; however, it was at par with BAP 8 mgl-1 + BA 3 mgl-1 at 75 days after inoculation.At 90 days after inoculation, maximum callus percentage (29.3) was found under BAP 8 mgl-1+ BA 4 mgl-1. At 105 days after inoculation, callus percentage was maximum callus (33.0%) was noted under the treatment combination of BAP 8 mgl-1+ BA 4 mgl-1, however, it was significantly at par with BAP 8 mgl-1+ BA 3 mgl-1, while the minimum (9.3%) was recorded under control again. The earliest shoot initiation (21.0, 22.0 days, respectively) was noted under BAP 8 mgl-1 and BA 5 mgl-1, separately; while it was statistically earliest i.e. 20.66 days in combination with BAP 2 mgl-1+ BA 5 mgl-1. Maximum shoot length (0.76 cm) was recorded in the treatment of BAP 8 mgl-1. at 20 days after shoot initiation.Maximum shoot length (3.06 cm) was noted under BAP 8 mgl-1 alone which statistically superior to other under BAP alone treatments while it recorded minimum under control at 40 days after shoot initiation. Under BA treatments, the maximum shoot length (2.26 cm) was noted with BA 4 mgl-1 and 5 mgl-1 both; however, it was at par with BA 2 mgl-1 and 3 mgl-1 at 40 days after shoot initiation. With the effect of BAP and BA combinations, the maximum shoot length (3.23cm) was recorded under BAP 8 mgl-1+ BA 5 mgl-1 at 40 days after shoot initiation. The minimum duration of ischolar_main initiation (14.66 days) was noted under the treatment of Indole Butyric acid 4 mgl-1 ; however, it was significantly at par with indole butyric acid 2 mgl-1 and 3 mgl-1. The maximum duration (34.33 days) was observed under control. Minimum number of ischolar_mains (4.0 ischolar_mains) were recorded under the treatment applied 1 mgl-1 IBA in culture medium. Further, number of ischolar_mains was found maximum 10.33 ischolar_mains under the treatment of 5 mgl-1 IBA followed by 4 mgl-1 IBA concentrations. Culture medium with IBA 5 mgl-1 showed maximum ischolar_main length (1.66 cm) followed by IBA 4 mgl-1 , 3 mgl-1 and 2 mgl-1 with 1.56 cm, 1.40 cm and 1.06 cm, respectively. It was concluded that BAP 8 mgl-1 and BA 5 mgl-1 separately performed better results on account of callus formation, shoot initiation and multiplication of shoots whereas with their combination viz., BAP 8 mgl-1 +BA 4 mgl-1 showed best result on the above parameters. For ischolar_main initiation and its development IBA 5 mgl-1 was found to be the best among all the treatments.Keywords

The genus Neolepidozia Fulford & J.Taylor is recorded in Indian bryoflora and N. wallichiana (Gottsche) Fulford & J.Taylor has been described and illustrated from Anjaw and Lower Dibang Valley districts of Arunachal Pradesh in Eastern Himalaya, India. The Indian plants of the species are little atypical in the size of main stem leaves and the number and size of main stem leaf-lobes, but the deviations are limited within the variations exhibited by the species across its range of distribution.Keywords

Changing climate of a region coupled with spatiotemporal variability of rainfall has a significant effect on groundwater recharge. An effort has been made in this study to analyse the pre- and post-monsoon average groundwater depths of different blocks in Kurukshetra district, Haryana, India. The stochastic analysis of groundwater depth was carried out using auto regressive integrated moving average (ARIMA) model. Best-fitted models ARIMA (2, 1, 1) and ARIMA (0, 1, 2) were used for prediction of pre- and post-monsoon groundwater depth fluctuations up to the year 2020. Results indicate that by the year 2020, average groundwater depth in the pre- and post-monsoon seasons in the district is expected to decline by 5.63 and 5.72 m respectively, over the base year 2010. Results of this study will be helpful in evolving strategies for groundwater development and management.Keywords

In this paper a novel method for effectively denoising the extremely corrupted image by fixed value impulse noise using robust estimation based filter is proposed. The proposed algorithm classifies the pixels of localized window in to "corrupted" or "uncorrupted" and removes only corrupted pixels by robust estimation or by left modified neighbor. It is shown that the proposed filter effectively removes the impulse noise while preserving the good image quality. The visual and quantitative results proves that the performance of proposed filter in the preservation of edges and details is better even at noise level as high as 95%.Keywords

Welding of Al-Zn-Mg alloy has been carried out by using AG conventional continuous current and pulsed current and pulsed current Tungsten inert gas (TIG) welding processes. The influence of various welding parameters on the soundness of the weld was studied by estimation of flaws in it. The effect of flaw size present like a crack inside the weld on the tensile strength of the weld has been determined. The influence of flaw size on the fracture toughness of the weld deposit has also been studied. It has been observed that for small flaws the failure is net stress controlled, whereas for large flaws the failure has been found to be stress intensity controlled.- Impact of Demonetization on Indian Economy

Objectives: The impact for demonetization has been mentioned, illustrating how similar events have had an historical analogy. The experts estimate has been used to support reasonable arguments made in context of requirement of monetary policy change.
Methods/Statistical analysis: Demonetization is a monetary policy which functions to remove currency of higher denomination which is currently in circulation. Reasons for its execution are restricted to each government and the need of the people. Although in best interest of the country and stabilizing the economy, demonetization reaches to sectors both organized and unorganized.
Findings/Results:Its effects are socio-economic which results in the desired outcome planned before, while bringing the policy in effect. Measures by the Government of India to demonetize with effect from 8th November 2016 will redefine business and investment in India and will lead this country to where it really belongs, in a league of developing nations contributing to the development of the entire world. The outcomes post demonetization has been discussed and its future implications have been mentioned in this manuscript. The assumptions made while applying policy change regarding the creation of urge to learn and implement smart IT solutions have also been mentioned illuminating desire for technological growth in the country. The article also follows through both advantages and disadvantages of demonetization.
Applications: Monetary Policy change, establishing business in a new economic environment.

The foraging behaviour of honey bees viz., Apis dorsata, Apis florea, Apis cerana indica and Apis mellifera were recorded on mustard crop. The observations on visiting of honey bees showed that the neem product, achook was found least toxic to honey bees due to their higher visits i.e. 3.00, 4.33, 4.33, 6.33 and 6.66 per three minutes per sq. m area just after, after 24, 48, 72 hours and after 5 days of application followed by bioneem i.e. 2.00, 3.00, 3.66, 5.66 and 6.33 visits, respectively. Nimbicidine also provided 1.33, 2.33, 3.00, 5.33 and 5.66 visits of honey bees 3 minutes in one square metre area in comparison to rest of the treatments. While maximum visits were recorded in untreated plot i.e. 6.66, 7.00, 7.33, 8.00 and 7.33 visits. Thus, achook and bioneem were found safer to honey bees and recommended to the farmers for the control of aphids (Lipaphis erysimi) in mustard crop.Keywords

Experiment was conducted using weighing-type field lysimeters to determine single and dual crop coefficients (Kc) and to estimate water productivity of mustard (Brassica juncea) cultivar, Pusa Vijay (NPJ-93) during rabi 2013-14 and 2014-15. It was observed that the single crop coefficient (Kc) during rabi 2013-14 was 0.39, 0.72, 1.02 and 0.5 for initial, development, mid and late stages respectively. While in dual Kc the value of Kcb (basal crop coefficient) was 0.19, 0.55, 0.91 and 0.24 for the four stages, respectively. During rabi 2014-15, the single Kc was 0.36, 0.63, 1.04 and 0.44 and for dual Kc the value of Kcb was 0.17, 0.46, 0.91 and 0.23 for four stages respectively. Relationship between Kcb and leaf area index as well as between Kcb and growing degree days was also established. Water productivity was estimated to be 14.9 kg/ha-mm corresponding to grain yield of 2.34 t ha-1 with 157 mm of total irrigation water applied during rabi 2013-14. Whereas during rabi 2014-15, water productivity was 15.4 kg/ha-mm with grain yield of 2.89 t ha-1 with 187 mm depth of applied irrigation. Nonetheless, the estimated crop coefficients of mustard can be used for judicious irrigation scheduling in order to enhance water productivity in semi-arid environment.Keywords

Photonic crystal fibers (PCF) are more versatile, intriguing and promising than conventional optical fiber. PCFs are divided into two different kinds, the index-guiding PCF and the photonic band-gap (PBG) effect PCF. In conventional index-guiding PCF, there is a lattice of air holes in the silica background, which surround the core. Light in this fiber is guided through the high index solid silica core by total internal reflection mechanism. Fundamentally different from all high index core conventional photonic crystal fiber, in this paper, we propose a new type of Photonic Crystal Fiber (PCF) structure; where instead of using the air-holes in the cladding region, we use boron doped solid silica rods in order to reduce the problems associated with deformities of air-holes in the fabrication of PCF. Also, we analyze few of the properties of the proposed photonic crystal fiber structure such as Endlessly Single Mode(ESM) property and tunable dispersion, and compared with conventional photonic crystal fiber.Keywords

Recent technological advances in communications and computation have enabled the development of low-cost, low-power, small in size, and multifunctional sensor nodes in a wireless sensor network. Since the radio transmission and reception consumes a lot of energy, one of the important issues in wireless sensor network is the inherent limited battery power within network sensor nodes. Therefore, battery power is crucial parameter in the algorithm design to increase lifespan of nodes in the network. In addition to maximizing the lifespan of sensor nodes, it is preferable to distribute the energy dissipated throughout the wireless sensor network in order to maximize overall network performance. Much research has been done in recent years, investigating different aspects like, low power protocols, network establishments, routing protocol, and coverage problems of wireless sensor networks. There are various routing protocols like location-aided, multi-path, data-centric, mobility-based, QoS based, heterogeneity-based, hierarchical routing, hybrid routing, etc., in which optimal routing can be achieved in the context of energy. In this paper, the focus is mainly driven over the survey of the energy-efficient hierarchical cluster-based available routings for Wireless Sensor Network.Keywords

Normally groundwater recharge is estimated using methods based on water balance, water table fluctuations, fixed factor of annual rainfall and tracer movement. In many of these methods water stored in the vadose zone and evapotranspiration are not accounted properly. These factors control groundwater recharge to a large extent, particularly in arid and semi-arid regions which are normally characterized by a deep water table, thick vadose zone and high evapotranspiration. In this study, HYDRUS-1D and MODFLOW models were used to assess the recharge flux and groundwater recharge in an area under a semi-arid region giving due consideration to important vadose zone processes. Cumulative recharge flux at water table in various sub-areas varied from 20.01 cm to 23.43 cm (29.26% to 34.26% of the monsoon rainfall). The average groundwater recharge was 22.2%. Total surface runoff in various sub-areas varied from 3.39 cm to 14.36 cm (5% to 21% of the monsoon rainfall). Evapotranspiration was found to be a major recharge controlling factor. Reference evapotranspiration varied from 37.19 cm to 45 cm (54% to 66% of the monsoon rainfall). Natural recharge under the prevailing pumping rate and pumping schedule was 23.3% of the monsoon rainfall. Simulation results revealed that if all the surface runoff is retained in the area, water table will rise by 1.46 m.Keywords

In the present study we estimate the velocity and thickness of the Patseo glacier, Himachal Pradesh, India. The average velocity of the glacier was estimated as ~5.47 m/year using co-registration of optically sensed images and correlation (COSI-Corr) method. The glacier thickness was found to vary between 12 and 278 m, with an average value 59 m. The total glacier ice volume was estimated as ~15.8 × 107 m3, with equivalent water reservoir of ~14.5 × 107 m3. Ground penetrating radar (GPR) surveys were conducted during 2004 and 2013 for validation of the estimated glacier thickness. The glacier thickness estimated using COSI-Corr method was found to be in agreement with GPR-retrieved glacier thickness (RMSE = 4.75 m; MAE = 3.74 m). The GPR profiles collected along the same geographic locations on the glacier during 2004 and 2013 showed a reduction in ice thickness of ~1.89 m, and thus resulting in an annual ice thickness decrease of ~0.21 m. The glacier area was estimated for 2004 and 2013 using LISS IV satellite data and found to be ~2.52 and ~2.30 sq. km respectively. This shows an annual reduction of ~0.024 sq. km in glacier area. The total annual loss in glacier ice volume was estimated as ~4.55 × 105 m3. This loss in the glacier ice volume of the Patseo glacier is supported by the snow and meteorological observations collected at a nearby field observatory of Snow and Avalanche Study Establishment (SASE). The climate data collected at SASE meteorological observatory at Patseo (3800 m), between 1993–94 and 2014–15 showed an increasing trend in the mean annual temperature and a decreasing trend in winter precipitation.Keywords

Global warming and climate change and its impact on crop water requirement are a major concern of this century. It has been established that the regional and global temperature is rising due to increased concentration of green house gases in the atmosphere. Rising temperature is expected to affect the crop water requirement. This study was undertaken to evaluate the trend and predict the changes in climate parameters, and assess the impact of climate change on crop water requirement using local weather data. Auto Regressive Integrated Moving Average (ARIMA) model was used for forecasting the future climate trend. Assessment of impact of climate change on crop water requirement was done for different climate change scenarios. Scenarios considered for assessment were based on ARIMA, Indian Network for Climate Change Assessment (INCCA) and Inter-Governmental Panel for Climate Change (IPCC) predictions. Crop water requirement of various crops would decrease by 7.5 to 14.2 mm by 2030s if it is determined using all important climatic parameters. Increase in water requirement varied from 13 to 77.5 mm for rice and 7.2 to 43.5 mm for pearl millet depending on the scenarios. Results indicate that crop water requirement did not increase if it was estimated using all important climatic parameters even though the average temperature increased during this period. However, if only rise in temperature is considered, crop water requirement would increase under all scenarios considered in this study.Keywords

In this study impact of climate change on groundwater recharge is investigated and the carbon emission from groundwater irrigation is assessed under projected climate change scenarios for Karnal district of Haryana state in India. HYDRUS-1D and MODFLOW models were used to simulate the climate change impacts on groundwater recharge for different projected climate change scenarios. Simulation results showed that groundwater recharge would increase marginally by 2030 over the baseline year of 2008 under the scenario based on ARIMA predictions, which considered the effect of all climate parameters. However, under the scenarios, which considered only rise in temperature, groundwater recharge would decrease by 0.07–0.22 m. Rise in temperature by 3.5°C and 4.3°C along with 9% and 16% increase in rainfall over the base year would increase the recharge by 0.09 m and 0.14 m respectively. The study also revealed that the effect of climate change on cumulative recharge would be more in sugarcane fields than in rice fields. Carbon emission of groundwater irrigation under the scenarios based on rise in temperature only would increase by a minimum of 12 kg CO2/ha in pearl millet crop by the year 2030 to a maximum of 3250 kg CO2/ha for sugarcane crop by the end of this century. Estimated total carbon emission in 2030 would be 345,857 metric tonne from groundwater irrigation in Karnal district which is 87,474 metric tonne more than the baseline emission.Keywords

This article analyses the blue, green and grey water footprints and virtual water flows within the Gomti river basin (GRB) in India. Assessments were made at spatial resolution of agricultural production units (APUs). An APU is a homogeneous spatial unit delineated on the basis of soil type, agro-ecological region and district boundaries. Water footprints of crop production and consumption were compared to arrive at virtual water balance within the GRB. Results show that water footprint of GRB was 12,773 million m3 year–1. Crop production was the largest water consumer accounting for 95.5% of water footprint within the basin. The higher proportion of blue water footprint (47.3%) indicates the dependence of GRB on irrigated agriculture. Contribution of rainfed agriculture to total water footprint was about 11.2%. Considerable portion of blue water is used in the production of low value water-intensive crops. The GRB was assessed as a net virtual water importer, indicating its dependence on the water resources of other river basins; it imports 2945 million m3 virtual water annually. This scenario can be changed if the area allocated to different water-intensive crops is optimized and limited to the extent that meets the consumption needs within the basin, leading to reduction in production surplus of these crops.Keywords

An avalanche accident was occurred on 5 January 2018 on Chowkibal–Tangdhar road in Kupwara district, Jammu and Kashmir about 6 km from Chowkibal village. One light passenger vehicle was swept away in the avalanche and 10 persons lost their lives. In this communication, we study the cause of avalanche accident and simulate the snow avalanche flow using Rapid Mass MovementS model. Total snow depth recorded at the nearest observation location from the accident site was 31 cm and fresh snow of the storm was 24 cm. Avalanche condition on slope was building up and the Snow and Avalanche Study Establishment issued an avalanche warning of ‘Low Danger’ for the Chokibal–Tangdhar road axis. Maximum thickness of avalanche debris on road was observed to be 3.0 m. Flow simulation showed maximum velocity of avalanche to be ~25 ms–1, maximum impact pressure ~9.39 × 104 kg m–1 s–2 and maximum height of avalanche flow ~3.0 m.Keywords

This study analyses the drought events for the Gomti basin in Uttar Pradesh (UP), India using the standardized precipitation index (SPI) at the spatial and temporal scales. Daily precipitation data for 14 districts in the Gomti basin for 41 years (1971–2011) were used to calculate the SPI for 1-month, 4-month, 6-month and 12-month time scales. Results for the 6-month (June–November) and 12-month time scales were similar and drought years were observed in 1972, 1979, 1987, 1993, 1994, 2002 and 2010. The 4-month SPI was analysed for the main monsoon months in the Gomti basin, i.e. from June to September. Results showed that significant drought occurred during the monsoon months of 1979, 1987, 1993, 2002, 2009 and 2010. For drought analysis at the spatial scale, the Kriging interpolation method available in ArcMap was used. The 12-month SPI showed that the frequency of severe and extreme drought was more in the upper regions of the basin during 1971–2000 whereas drought frequency was more in the central and lower regions of the basin during 2001–2011. Further, the de Martonne aridity index was calculated for the period 1971–2007 and its correlation with the 1-month SPI for the period 1971–2007 was evaluated.Keywords

A field experiment was conducted for two consecutive years to develop management alternatives for wheat cultivars (salt-tolerant and salt non-tolerant) cultivated under irrigated saline environment (groundwater, 4, 8 and 12 dS m–1) and foliar potassium fertigation. The grain yield of wheat cultivars decreased with the increase in salinity levels of irrigation water. The foliar potassium fertigation during the heading stage of wheat cultivars ameliorated the adverse effect of salinity and resulted in the increase in grain yield. In this study, empirical equations for wheat yield known as production function have been developed. The production functions were developed keeping grain yield parameter as output, besides the many input parameters pertaining to quantity and quality of the irrigation water, quantity of potassium applied as foliar spray and rainfall depth during the crop growth period. The production function with higher coefficient of determination (R2) may be used to predict grain yield of both salt-tolerant and salt non-tolerant cultivars under different saline irrigation regimes, rainfall and irrigation water depths, besides the dose of potassium sulphate (K2SO4) for foliar spray. The production function which gave the highest R2 value (i.e. 0.82 for KRL-1-4 and 0.97 for HD 2894 wheat cultivars) could be used for foliar spray under different salinity regimes with high expectation of grain yield. The predicted grain yield and estimated quantity of potassium under different salinity levels of irrigation water may prove useful to different stakeholders for enhancing the wheat yield in high saline water areas. The stakeholders can predict the grain yield under similar circumstances as explained in this experiment and estimate the appropriate potassium doses to be applied for enhancing the wheat yield.Keywords
