Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Effect of integrated nutrient management in pigeon-pea based intercropping system on soil properties, growth and yield of pigeon-pea, black-gram, maize on mollisols of the tarai region
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2010-01) Singh, Ashutosh; Mishra, H.S.
    A field experiment were conducted during kharif season of 2007 and 2008 at N. E. Borlaug Crop Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand to study the effect of integrated nutrient management in pigeon-pea based intercropping system on soil properties, growth and yield of pigeon-pea, black-gram, maize on Mollisols of the Tarai region. Treatments comprised 3 cropping system (sole pigeon-pea, pigeon-pea + black-gram and pigeon-pea + maize), 2 inoculation (PSB-inoculation and uninoculation) and 3 levels of FYM (0, 2.5 and 5.0 t ha-1). Eighteen treatment combinations were replicated three times in a factorial randomized block design. The soil was sandy loam in texture, medium in organic carbon (0.81%), low in available N (199.8 kg ha-1), and medium in available P (17.2 kg ha-1) and available K (219.7 kg ha-1) contents with pH 7.2. The crop pigeon-pea ‘UPAS-120’, black-gram ‘PantUrd-40’ and maize ‘Surya’ was sown on 2nd and 16th July during 2007 and 2008, respectively. A basal dose of 20 kg N, 40 kg P2O5 and 30 kg K2O ha-1 for pigeon-pea and black-gram and for maize 60 kg N, 60 kg P2O5 and 40 kg K2O ha-1 was furrow placed at the time of sowing and half dose (60 kg N) for maize was applied 30 and 50 days after sowing. Seed of pigeon-pea and blackgram were inoculated with PSB (Bacillus polymyxa) @ 20 g culture kg-1 seed before sowing. Intercrop was harvested 110 and 105 DAS (black-gram) and 94 and 83 DAS (maize) during 2007 and 2008, respectively. The pigeon-pea crop was harvested on 29th December in 2007 and 30th December in 2008. Most of the growth parameters viz. plant height, branches, dry matter production, nodules number and their weight, yield attributes and yield of pigeon-pea were significantly higher under pigeon-pea + black-gram cropping system. Similar results were also obtained with PSB-inoculation and FYM @ 5.0 t ha-1 for all crops. Pigeon-pea grain equivalent yield was reported significantly higher under pigeon-pea + black-gram cropping system followed by pigeon-pea + maize and sole pigeon-pea. Protein content and yield in pigeon-pea increased under pigeon-pea + black-gram cropping system. PSB-inoculation and 5.0 t FYM ha-1 were also increased the protein content and yield in pigeon-pea and black-gram. Nutrient concentration (N, P and K) in plant parts and its uptake by crop of pigeon-pea were maximum under pigeon-pea + black-gram cropping system followed by sole pigeon-pea and pigeon-pea + maize cropping system. PSB-inoculation and FYM application @ 5.0 t ha-1 increased the nutrient content (N, P and K) and its uptake by all the crops at all the growth stages. Pigeon-pea + black-gram cropping system, PSB-inoculation and FYM @ 5.0 t ha-1 significantly increased microbial population and dehydrogenase activity in soil after the harvest of pigeon-pea. There was no significant effect of the treatments on soil pH and EC. PSB-inoculation non-significant increased the organic carbon, available N and K in soil but significantly increased the available P in soil. However, available N, P and K content significantly increased by intercropping system, PSB-inoculation and FYM application while available K in soil did not significant increased by FYM application. Application of different treatments did not affect physical properties of soil significantly after harvest of pigeon-pea over control in both the years. Finally, pigeon-pea + black-gram cropping system supplied with PSB-inoculation and FYM @ 5.0 t ha-1 was found to be suitable in terms of both soil health and crops performance which Needs further investigation to be recommended to field level.

    Simulation of growth and yield of wheat (Triticum aestivum L.) and soil moisture using Ceres Wheat Model in Bhabhar and Tarai agro-climatic zone of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2011-08) Khanday, Ab Shakoor; Kushwaha, H.S.
    Field experiments were conducted at Norman E. Borlaug Crop Research Center of G.B. Pant University of Agriculture and Technology, Pantnagar (Latitude 290 N, Longitude 79030´ E and Altitude 243.84 m above msl) during rabi seasons of 2009-10 and 2010-11 to simulate the effect of various irrigation treatments on growth and yield of wheat (Triticum aestivum L.) and soil moisture using CERES-wheat model in Bhabar and Tarai agroclimatic zone of Uttarakhand. Experiment was laid out in RBD under five irrigation treatments viz. irrigations at crown root initiation (CRI) stage , I1; CRI + late jointing (LJ) stage, I2; CRI + LJ + milking (M) stage, I3; CRI + late tillering (LT) + flowering (F) stage + M, I4 and CRI + LT + LJ + F + M, I5 of the wheat crop with three replications. The analyzed data of experiments have shown that maximum simulated (3.98) and observed (5.01) LAI was obtained at 90 DAS during 2010-11 compared with 2009-10. Days taken to anthesis were underestimated during the 2009-10 and were overestimated during 2010-11. Model simulated the days to physiological maturity better (R2=0.948) in all the treatments during 2010-11. The days to harvesting maturity under all the irrigation treatments were underestimated by the model during both the years. A slightly higher efficiency of model (R2=0.674) was obtained in 2010-11. The harvest index was also overestimated under all the treatments except I2 during 2009-10 and I4 in 2010-11 crop season. The decrease in observed soil moisture content with increase in the soil depth was simulated well by the model under all the irrigation treatments. The perfect match between simulated and observed soil moisture content was observed at 130 DAS under I2 at 45-60 cm and at 104 DAS under I5 treatment at 15-30 cm soil depth during 2009-10. The extractable soil moisture (ESM) was simulated best at 62 DAS under I3 during 2009-10 and at 20 DAS under same treatment during 2010-11. The model was found to perform most efficiently in predicting the TPSM at 130 DAS under I2 treatment during 2009-10 and at 44 DAS under I4 treatment during 2010-11. Results have shown that maximum root length density (1.31 cm cm-3) was obtained under I5 treatment at 0-30 cm soil depth at 90 DAS during 2009-10. Higher value of shoot count (365.62 m-2) was obtained under I5. Significantly more number of days to anthesis (80.00 and 88.33) ,physiological maturity (117.67 and 127.33 ), harvesting maturity (137.00 and 151.00), grain yield (49.21 and 48.90 q ha-1), straw yield (104.23 and 104.90 q ha-1), biological yield (153.44 and 153.80 q ha-1) and water use (41.89 and 46.97 cm) were obtained under I5 during 2009-10 and 2010-11 crop seasons. Significantly more spike length (10.05 and 11.03 cm ) and 1000 grain weight (38.02 and 38.70 g) was recorded under I5 and I4 during 2009-10 and 2010-11, respectively. The effect of different irrigation treatments on the grain weight per spike was found to be non-significant during both of the crop seasons. It is concluded from this study that CERES model simulated growth, development and yield of wheat with reliable precision during both years. In simulating most of wheat crop characters the model was observed to be more efficient in 2010-11 than 2009-10, which may be attributed to the increased crop duration, well distributed rainfall and relatively lower atmospheric temperature during 2010-11. The CERES wheat model has tremendous potential in predicting the yield of wheat crop and soil moisture under diverse agro climatic conditions especially in the locations where capital is the main constraint in conducting of the field experiments and providing of the necessary lab facilities.

    Effect of nutrient management and postemergence herbicides on Glycine max-Rhizobium symbiosis and soil properties
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2011-09) Das, Shrila; Narendra Kumar
    Two field experiments were conducted during kharif season of 2008-09 on soybean variety PS1347 at the Norman E. Borloug Crop Research Center of G.B. Pant University of Agriculture and Techonology, Pantnager (Uttarakhand) and one laboratory experiment to evaluate the “Effect of nutrient management and post-emergence herbicides on Glycine max - Rhizobium symbiosis and soil properties” In first experiment, 50% organic + 50% inorganic nutrient sources showed highest nodule number, nodule dry weight, significantly more plant dry weight and grain yield of 1797.91 kg ha-1 and straw yield of 3106.94 kg ha-1 over 100 % organic treatment. This treatment also recorded highest N and P content in grain and straw as well as uptake of N (121.61 kg ha-1) by grain and straw (58.12 kg ha-1) and uptake of P (11.85 kg ha-1) by grain and by straw (13.83 kg ha-1). Maximum number of soil bacteria (23.20 X 107 CFU g-1 soil) and actinomycetes (46.84 x 106 CFU g-1 soil) was found in 50 % organic + 50 % inorganic treatment at 60 DAS. However, maximum fungal population (13.75 x 105 CFU g-1 soil) was recorded after harvest. This treatment also gave higher number of soil rhizobia and PSB than 100 % inorganic treatment at both the intervals. The highest soil available N (286.94 kg ha-1), P (23.46 kg ha-1) and K (139.03 kg ha-1) were recorded in 50 % organic + 50 % inorganic treatment. 100% inorganic and INM+IPM treatments were better than 100% organic for nodule number, nodule dry weight, plant dry weight, yield and N and P content and uptake, but soil microbial population, microbial biomass and dehydrogenase activity were higher in 100% organic treatment than 100% inorganic and INM + IPM treatments. The cropping systems did not significantly affect nodule number, nodule dry weight, grain and straw yields, and N and P content and uptake. However, significantly more plant dry weight was recorded in soybean-chickpea cropping system than soybean-wheat. The population of soil rhizobia and phosphate solubilizing bacteria (PSB), microbial biomass carbon were significantly higher in soybean-chickpea cropping system in comparison to soybean-wheat system after harvest. The cropping systems did not show significant effect on soil organic carbon, pH, electrical conductivity, bulk density and available N, P and K. Interactions between nutrient management and cropping systems were significant for nodule number at 60 and 90 DAS, nodule and plant dry weight at 30 and 90 DAS, grain and straw yields, N content and uptake by grain and straw, P content and uptake by grain. Significant interactions between nutrient management and cropping systems was also recorded for total soil bacteria, actinomycetes and PSB population after harvest, total fungal, rhizobial population and microbial biomass carbon and dehydrogenase activity in soil at 60 DAS and after harvest. In second experiment, maximum nodule number per plant, nodule and plant dry weight, grain yield of 2185.17 kg ha-1 and straw yield of 3018.50 kg ha-1 were found in two hand weeding treatment, while weedy check control showed minimum. The uptake of N and P by grain and straw was significantly more in two hand weeding treatment than all other treatments. This treatment also showed maximum number of soil microorganisms including rhizobia, PSB, microbial biomass carbon and dehydrogenase activity at 60 DAS as well as after harvest. By increasing concentration of haloxyfop ethyl 10 EC from 75 to 100 g a.i. ha-1, decline in soil microbial population, microbial biomass carbon and dehydrogenase activity were recorded at 60 DAS as well as after harvest. Among herbicides, fenoxyprop ethyl 9 EC @ 100 g a.i. ha-1 was found most effective in controlling weeds in soybean and showed better nodulation, plant growth, yield, nutrients uptake and soil health parameters. In third experiment, the increase in concentration of herbicides significantly reduced the population of Bradyrhizobium japonicum and PSB (except 0.3 and 0.4 per cent concentration). Maximum number of Bradyrhizobium japonicum (110.66 X 104 CFU mL-1) and PSB (84.73 X 104 CFU mL-1) was recorded in the control and minimum of 19.57 X 104 CFU g-1 soil and 14.69 X 104 CFU mL-1 soil at 0.5 per cent concentration, respectively.

    Scheduling of irrigations for European dill (Anethum graveolens L.) under varying water table conditions
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2010-02) Mehra, Menka; Kushwaha, H.S.
    Study was undertaken for scheduling of irrigation in European dill (Anethum graveolens L.) crop through field-lysimeter and field-plot experiments conducted during rabi seasons of 2007-08 and 2008-09 at Crop Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar Uttarakhand, (Latitude 290 N, longitude 79o 30’ E and altitude of 243.84 m above msl). The soil of lysimeters is silty clay loam in texture and is associated with shallow to deep water table conditions. While the soil of field plots is sandy loam in texture and is associated with very deep water table condition. Six irrigation treatments viz I0 (rainfed), I1 (one irrigation at 21 days after sowing, (DAS), I2 (two irrigations each at 21 and 42 DAS), I3 (irrigation at 40 per cent depletion of available soil moisture), I4 (irrigation at 60 per cent depletion of available soil moisture) and I5 (irrigation based on IW : CPE ratio as 0.6) were selected for the experiment to study the effect of irrigation on growth, development, yield and yield attributes of the crop in both field-lysimeters and in field-plots. All other standard agronomic and plant protection measures were followed to grow the crop during both the years. Results have shown that under lysimeter experiment, the highest plant height (131.4 and 131.9 cm) and maximum number of fruits per umbel on main shoot (1170.86 and 1199.61), primary branches (747.66 and 738.91), secondary branches (495.34 and 492.83) and tertiary branch (288.01 and 286.86) were found in I4 treatment in which irrigations were scheduled based on 60 per cent depletion of available soil moisture under 60 cm water table condition in field-lysimeters during 2007-08 and 2008-09, respectively. The minimum number of days taken by the crop for 50 % flowering was 95.75 and 95.50 under 30 cm, 95.25 and 94.25 under 60 cm and 94.75 and 94.00 under 90 cm water table during both these respective years. Highest seed yield of 2047 and 2194 kg ha-1 was obtained from the interaction of I4 with 60 cm water table during both these respective years. The highest water use efficiency of 37.12 and 38.65 kg ha-1 cm-1 was found in I4 under 60 cm water table during both these respective years. Under field experiment, highest plant height of 102.16 and 102.86 cm was found in I4 and was at par with I5, however, the maximum seed yield of 1725 and 1771 kg ha-1 was found under I4 irrigation treatment, being at par with I5 during 2007-08 and 2008-09, respectively. The organic carbon and available N, P and K in soil after the harvest of crop were found to be higher in I4 after compared with all other treatments Therefore, it can be concluded from this study that for obtaining optimum seed yield of European dill under medium (60 cm) water table, crop must be irrigated at 60 per cent depletion of available soil moisture.
