Higher herbage and oil yield was recorded in pure fields of Mentha crops than their crops grown under Poplar and Eucalyptus stands. The first harvest of each crop of Mentha spp., yielded higher fresh herbage as well as oil in comparison to second harvest, both in pure as well as intercropped with Poplar and Eucalyptus stands. Maximum herb and oil yield was produced by M. arvensis and minimum by M. piperita, both in pure as well as intercropped stands. The trees intercropped with M. arvensis produced higher quantity of litter and minimum was in M. piperita. The quantity of litter production was higher in poplar than Eucalyptus. The concentration of nutrients (NPK) in the litter decreased with increasing age of stands. It was higher in Poplar than Eucalyptus. The total addition of nutrients was also recorded higher in Poplar than Eucalyptus.

Status of lac production in lac growing districts of Jharkhand has been assessed with parameters like minimum, maximum, average production and simple growth rate for the period 2006-07 to 2009-10. A comparison of growth rate in three years period (2006- 07 to 2008-09) with those in four years period (2006-07 to 2009-10) has also been made for understanding the status of change in production. The analysis of data showed that Ranchi district has highest production of lac to the tune of 28.9 per cent of total lac production of the state followed by Simdega (24.5 per cent) and Gumla (17.9 per cent). The positive growth rate in lac production was recorded in Gumla, West Singhbhum and Simdega to the tune of 21.6, 6.32 and 28.9 per cent per annum respectively during last four years. Highest negative growth rate was recorded in Latehar (-69.3 per cent) district. Comparative analysis of last three and four years period growth rate showed that Gumla district recorded positive growth with slight reduction (24.9 to 21.6 per cent). Simdega district reported very good improvement (-21.2 to 28.9 per cent) and another district which recorded good improvement was West Singhbhum (- 17.3to 6.3 percent).Keywords

District-wise and crop-wise status of lac growing districts of Madhya Pradesh have been assessed with parameters like minimum, maximum, average production and simple growth rate (SGR) for four years (2006-07 to 2009-10). The study reported that the state contributes 16 per cent production of the country; however, the growth rate during the study period was negative and to the tune of 10.1 per cent per annum. Seoni district contributed maximum in lac production (41.6 per cent) followed by Balaghat (30.6 per cent), Hosangabad (8.4 per cent) and Mandla (7.0 per cent). Strain-wise growth rate for the whole state showed that both rangeeni and kusmi lac production attained a negative growth of 5.2 and 32.1 per cent per annum. Crop-wise growth rate for the state showed that rangeeni-summer attained positive growth (12.1 per cent per annum) while rangeeni-rainy registered negative growth(37.5per cent). Similarly,both kusmi-winter and kusmi-summer crop registered negative growth rate of 34.0 and 29.9 per cent per annum respectively.Major reduction in lac production was due to loss of rangeeni-rainy crop which caused less availability of broodlac for next season.Thus less production in one season indirectly affected production of succeeding season crops also.Keywords

In case of dryland cultivation practices intelligently on need to minimize cost of production of any crop. Tillage is one of the major operations of the crop production and is an important contributor to the total cost of production. In this regards an experiment has been conducted on two tillage systemi.e. conventional and reduce tillage system in order to save the energy in production of wheat crop comprising three tillage treatments in combination to three doses of fertilizer application. The data revealed that the highest yield of wheat of 29.33q/ha was recorded in 50% conventional tillage + weedicide + interculture followed by conventional tillage + interculture with a grain yield of 27.87q/ha. With regard to nitrogen application through different sources, the highest average grain yield of 29.00q/ha was recorded with 100%N through inorganic fertilizer followed by 50% N through organic + 50% N through inorganic fertilizers with a grain yield of 28.25q/ha. As for as energy requirement and cost of operation were higher in the conventional tillage system (2907.53MJ and Rs.11347.33) than in reduce tillage i.e. 50% CT+ interculture+ weedicide (2227.20MJ and Rs.10335.30) and 50% CT+ interculture (2281.56 MJ and Rs.9948.60), respectively. The benefit cost ratio ranged from 1.08: 1 to 1.41: 1Keywords

The present investigation was carried out in rainy season during 2009 and 2010 at Research Farm and Seed Testing Laboratory of Gochar Mahavidyalaya, Rampur Maniharan, Saharanpur, Uttar Pradesh with a view to study the influence of sowing time and plant geometry on plant growth and yield of okra. The experiment was laid out in split-split plot design with three replications and four dates of sowing in each season viz., 10 June, 24 June, 8 July and 22 July 2009 and 2010 taken in main plots and three plant geometries viz., 60 x 30 cm, 60 x 45 cm and 60 x 60 cm in sub plots and two varieties viz., Parbhani Kranti and Pusa A-4 in sub-sub plots. The plant growth and vigour which was evident from greater plant height, pod development, seed size and yield obtained in the crop sown on 10th and 24th June. Seed yield is correlated with the performance of yield contributing attributes and a perusal of data pertaining to seed yield components viz. per cent fruit set, number of pods per plant, pod length, pod thickness, number of seeds per pod revealed that the environment was more favourable for okra seed production when the crop was sown on 10th June and 24th June which were found superior in seed yield and its components over rest of the sowing dates.Keywords

Analysis of year wise lac production data in India during XI Plan (2007-2008 to 2011-2012) indicated average production by the country to the tune of 16.246 thousand tonnes. The Jharkhand state registered highest average annual production (6.306 thousand tonnes), sharing 38.82 per cent of total lac produced in the country. This is followed by Chhattisgarh (30.21%), Madhya Pradesh (13.66 %), West Bengal (6.97%), Maharashtra (4.96%), Odisha (2.27%), Uttar Pradesh (1.94 %), Assam (0.52%), Andhra Pradesh and Gujarat (0.30% each) and Meghalaya (0.06 %). In respect of state wise growth rate in lac production, the country registered negative growth rate to the tune of 8.38 per cent per annum. Amongst the major lac producing states, Jharkhand and West Bengal recorded positive growth of 12.19 and 9.94 per cent per annum respectively, during this period. Amongst the declining trend state, Madhya Pradesh recorded highest negative growth (-32.41 %) followed by Uttar Pradesh (-29.37%), Chhattisgarh (-26.76%), Maharashtra (-10.62%) and Odisha (-9.92%). The other minor lac producing states namely Assam, Gujarat, Meghalaya also registered declining trend during the period. Strain wise analysis of production data for various states was also carried out in an attempt to identify which type of lac suffered most during this periodKeywords

In this communication an effort has been made to develop a general non-site specific allometric relationship taking Tectona grandis grown in semi-arid Bundelkhand region without harvesting any tree. To determine the most appropriate predictor variable for producing the relationship, different physiological parameters of this tree species like diameter at breast height (dbh), basal diameter, tree height, forking height, collar diameter, etc. were collected from the standing trees from MP part of Bundelkhand region, comprising a total of 45 sites of 4 districts namely Guna, Vidisha, Chhatarpur and Tikamgarh. The dataset contained 418 trees with biomass ranging from 12.79 kg/tree to 12707.92 kg/tree, height ranging from 1.5 to 18.5 m and dbh ranging from 0.03 to 0.44 m. For developing the models; dbh, height, dbh × height and dbh2 × height were used as predictor variables. All four contrasting sites were taken for developing allometric models and after examining model residuals and site-specific relationships, it was found that using dbh2 × height alone as the predictor variable produced the most stable model. Thus it makes regional estimation of aboveground biomass production easier with precision as accurate as site-specific allometry.Keywords

This article sets up a single period value maximisation model for the firm based on stochastic end-of-period cash inflows, stochastic bankruptcy costs and taxes based on income rather than wealth. The risk- return tradeoff is captured in the Capital Asset Pricing Model.Thus, the model also assumes a perfect capital market and market equilibrium. The model establishes the existence of a unique optimal financial leverage at which the firm value is maximised, this leverage being less than the maximum debt capacity of the firm.Keywords

The treatments were comprised of mulching, borax @ 0.5 and 1.0 per cent, potassium sulphate @ 0.5 and 1.0 per cent, calcium chloride @ 0.5 and 1.0 per cent, calcium nitrate @ 0.5 and 1.0 per cent, GA3 @ 25ppm and 50 ppm, NAA @ 25ppm and 50 ppm in combination with mulching and water spray without mulching as control. The spray is to be done three times at different times at different stages during the year 2010 and 2011 which is given below-Ist spray on 15th January (i.e. before flower bud burst), IInd spray on 15th February (i.e. at panicle emergence) and IIIrd spray on 15th April (i.e. after fruit set). It may be concluded from the present studies that the application of CaNO3 improves flowering parameters, increases the number of fruits and fruit yield and K2SO4 increase the physical characters of fruit.

An experiment involving twenty four genotypes of chilli and three created environments (E0 – No spray, E1 – Single spray on NAA @ 40 ppm and E2 – Double spray of NAA @ 40 ppm) was carried out during spring summer season at Vegetable Research Centre, Pantnagar to determine the best genotype, suitable environment and their interactions for higher production of chilli. Out of the three environments, E2 was found better for red ripen fruit yield, number of fruits/plant, 100-seed weight, seed : husk ratio, minimum incidence of disease viz., anthracnose and leaf curl virus, whereas, significant variations were observed for all the 18 characters studied. Among genotypes viz., G23 (PC-2062), G24 (PC-2064) and G22 (PC-2057) produced significantly more number of fruits/plant and G20 (PC-7) followed by G21 (PC-56) and G2 (Co-4) performed better for weight of fruits/plant. Genotypes G23 and G21 produced 110.26 and 71.60 per cent higher yield over check variety Pant C-1, respectively. Longest fruits (13.59 cm) were obtained in G20 (PC-7) .More number and weight of seeds/fruit were recorded in G22 (PC-2057). Out of all the 72 interactions, G23E1 was found better for number and weight of fruits/ plant whereas, G23E1 (254.42 q/ha), G22E1 and G2E2 produced higher red ripen fruit yield over rest of the interactions.

Commensurate with this exponential growth in the depth and breadth of derivative markets and the range of financial products traded therein, there needs to be developed a comprehensive mathematical framework to support the, hitherto, empirically established features of trading strategies involving these instruments. It is the objective of this article, to provide a mathematical backup for the various properties of 'volatility trading' strategy using call options. Additionally, an attempt is made to elucidate the implications of behavior of various 'option Greeks' on volatility trading.Keywords

We fabricate PEDOT:PSS/n-Si heterojunction diode by deposition of Poly (3,4-ethylenedioxythiophene)- poly (styrenesulfonate) (PEDOT:PSS) on n-type Si wafer using spin coating process. In this study, temperature dependent electrical properties of the diode were investigated. This heterojunction diode showed a good quality rectifying behavior. It was found that the ideality factor increases and barrier height decreases with decrease in temperature. Such a behavior is attributed to barrier inhomogeneities. Resistivity measurements showed that resistivity decreases with increasing temperature.Keywords

Populations of threatened plants are declining rapidly in natural habitats due to various anthropogenic activities. Reinforcement of the dwindling populations through reintroduction is a promising aspect for conservation of threatened plants. However, due to lack of standardized propagation methods of such plants, mass production of planting materials has become a challenge, thereby constraining the replenishment process. Identification of factors constraining the seed germination of threatened plants and addressing it effectively, are among the most cost-effective strategies for large-scale multiplication and subsequent conservation of the threatened species. Similarly, conventional low-cost vegetative propagation techniques such as grafting, air layering, and regenerating plantlets from ischolar_main-suckers, apical meristems, and stem cuttings often prove more successful for multiplication than relatively costly micropropagation techniques. In this article, we present a few case studies on low-cost mass propagation techniques of threatened plant species of India through seed, stem/apical shoot cutting and airlayering, that helped in the restoration of the species.Keywords

A tractor drawn ‘subsoiler cum vermicompost and soil amendments applicator’ was design and developed to examine the basic concept for placement of organic manures and inorganic fertilizers in subsoil at different depth upto 400mm. The developed machine was evaluated in laboratory for discharge rate and distribution pattern of different organic manures viz., vermicompost, pressmud and FYM at three moisture states and soil amendments i.e. gypsum, lime, cement and rice husk. Prior to laboratory testing of the machine, the physical properties of materials were studied. The machine was also tested under field condition on the basis of changes in dry bulk density, specific draft and wheel slippage at 250, 300, 350 and 400 mm depths of operation.The results revealed that the bulk density was uniform throughout the soil profile after operating at 400 mm depth. The bulk density reduced to a maximum of 13.88 per cent. The specific draft for 400 mm depth of operation was found lower by 33.26 per cent than that at 250 mm depth. Whereas, the wheel slippage was found to a maximum of 21.07 per cent at the draft of 12.20 kN for 400 mm depth of operation. The results obtained during performance evaluation of developed machine on response of mustard crop have clearly revealed the advantage of subsoiling and deep placement of organic and inorganic fertilizers in terms of substantial increase in yield parameters.Keywords

Every year in India, an average of 1980 Cr of rupees is wasted due to weeds. Our country faces the total loss of 33 per cent of its economy from weeds. Shrinking farm lands, acute labour shortage, decreasing income per acre of cultivation, and economic frustration are some of the key factors hurting a farmer’s confidence in continuing farming. Weeding control is done by: mechanical weeding, thermal weeding: flaming, biological control, chemical control and by farming pattern. It has always been a problem to successfully and completely remove weeds and other innocuous plants and also earthing-up the crop. In order to overcome these problems weedingcum- earthing-up equipment was developed. This work involved the design and construction of low cost weeding-cum-earthing-up equipment, which consists of two main units viz., first weeding unit and second soil cutting and earthing-up unit. A serrated blade and two discs were selected for weeding and earthing-up operations, respectively. The weeding efficiency and cutting width of developed equipment was found 90.7 per cent and 35 cm, respectively.Keywords

A Langevin formalism is proposed for stock market dynamics with modeling of various economic market features from first principles. Various processes and effects that occur in the stock market are mathematically incorporated in the said formulation. The Fokker Planck equation corresponding to the Langevin equation so obtained is solved and shows deviation from Gaussian behavior of the rate of change of stock price PDF. The deviation relates to factors such as market efficiency, market depth, liquidity of the relevant stock and informational asymmetries.Keywords

A laboratory scale model of composite radial filter was designed, fabricated and tested for recharging aquifer with canal water. Charcoal (C), coarse sand (CS) and gravel (G) filter materials were placed in annular rings of developed radial filter in different combination of thickness, viz. 1 : 1 : 1, 1 : 1 : 2, 1 : 2 : 2 and 1 : 2 : 1 for four treatments T1, T2, T3 and T4 respectively. Flow equation for discharge through composite radial filter was developed and verified through experiments. The design depth of the filter for given discharge was also obtained. Sodium hypochlorite solution was injected through chlorination unit at the outlet of the radial filter to remove the bacteriological contamination of filtered water. The performance of composite radial filter was evaluated by analyzing canal water before and after filtration. Water quality parameters of filtered water were found to be within permissible limit at low flow rate (0.3 lps). The water quality parameters of filtered water from treatment T3 with thickness of 10, 20 and 20 cm for C, CS and G respectively was found to be comparatively better than other three treatments (T1, T2 and T4). The composite radial filter consists of C, CS and G filter media having thickness in ratio of 1 : 2 : 2 was found to be the best for recharging groundwater aquifer with canal water.Keywords

In the increasing globalisation era, movement of goods and planting materials between countries being carried out at ease, are potential factors of introduction of invasive alien insects, diseases, and weeds in India. Infested fruits carried by international travellers, cargo / sea shipments of wood logs, food trade, and accidental introduction through air travels were the potential ways of entry of invasive alien insects into any country. The entry of alien invasive pest causes huge economic damage by way of direct crop loss. In addition, the panic situation to save the crops results in indiscriminate use of chemical insecticides that is harmful to applicator, farmer and consumer. Frequent application of insecticides leads to reduction in natural enemies and pollinators there by having an adverse impact on the ecosystem. The present paper critically reviewes the existing plant quarantine regulations in India, recent invasive and migratory insect pest problems and way forwards to safeguard Indian Agriculture.Keywords

Regional-level studies aimed at identifying and assessing various types of extreme weather events and comprehending their effects on various sectors are crucial. In the present study, we have utilized the RClimDex software to compute the trend in temperature and precipitation extreme events in the Varanasi district of Uttar Pradesh, India, from 1980 to 2018. We employed both Mann–Kendall test and linear regression to test the statistical significance of the computed trend. Out of 13 temperature indices, 8 showed a significant trend while the remaining showed a non-significant trend. The annual mean maximum temperature, warm days, diurnal temperature range and a monthly minimum of maximum temperature had decreased significantly by 0.029ºC, 0.159 days, 0.032ºC and 0.122ºC/yr respectively, whereas cool days and cold spell duration had increased significantly by 0.264ºC and 0.372 days/yr respectively, indicating an increased cooling effect over the study area. Similarly, out of the 11 rainfall indices, only two showed a significant trend, while the remaining showed a non-significant trend. The increasing drought over the study area is evident as the number of rainy days and consecutive wet days have decreased significantly by 0.262 days and 0.058 days/yr respectively, with a non-significant increase in consecutive dry days during the same period. The weak negative non-significant trend of a maximum of five consecutive days of rainfall, very heavy rainfall days and total annual precipitation indicate the decreasing trend of floods. This study stresses the development of adaptation plans to overcome the adverse consequences of extreme weather events in Varanasi district.Keywords
