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.

    Soil test crop response study in chilli (Capsicum annum L.) for fertilizer recommendation
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-06) Deepak; Srivastava, Ajaya
    A field experiment was conducted during spring and summer 2011-12 at Crop Research Centre, G.B.P.U.A. & T., Pantnagar under AICRP on soil test crop response correlation to develop fertilizer adjustment equation for computing nutrient dose for targeted yield of Chilli on the basis of initial soil fertility and nutrient dose. Test crop Chilli was grown using three levels of nitrogen, phosphorus and potassium with control in three different fertility gradient stripes. Twenty four treatments were randomised in each strip and three blocks were made with different organic manure (FYM) level (0 t ha-1, 10 t ha-1 and 20 t ha-1). Chemical analysis was carried out to estimate organic carbon, available nitrogen, phosphorus and potassium in soil. Nutrient requirement to produce one quintal of Chilli was found to be 3.21 kg for nitrogen, 1.57 kg for phosphorus and 3.96 kg for potassium. Percent contribution for nitrogen, phosphorus and potassium was 42.37, 30.65 and 7.7 from soil; 20.57, 36.0 and 56.0 with FYM; 8.0, 35.0 and 51.0 from chemical fertilizer, respectively. Multiple regression type response function were fitted in to the data by selected soil test methods. Response type for nitrogen - + -, while for phosphorus it was + + - type and for potassium it was - - + type. Fruit yield was positively and significantly correlated with plant yield (0.571**), nitrogen uptake (0.611**), nitrogen (.611**) phosphorus (0.620**) and potassium (0.483**). Significant correlation of fruit yield was found with fertilizer nitrogen (0.476**), phosphorus (0.419**) and potassium (0.398**), and FYM (.317**). Suitability of soil test methods were evaluated by R² value of multiple regression equation and concluded that alkaline KMnO4 and Organic Carbon, Olsen’s and AB-DTPA and Normal neutral NH4OAC and AB-DTPA methods are suitable for the determination of available nitrogen, phosphorus and potassium, respectively. These findings may be used as guide for efficient fertilizer management by reducing cost of cultivation and increasing fertilizer use efficiency. Therefore soil test based fertilizer recommendation may be a useful tool for balanced fertilization of nutrients.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-07) Pandey, Anshul; Kushwaha, H.S.
    Experiment with Cowpea (Vigna unguiculta (L).Walp) (2n= 22) var. Pant Lobia -1 was conducted at N.E. Borlaug Crop Research Center of G. B. Pant University of Agriculture and Technology, Pantnagar (Latitude 290N, Longitude 790 30’ E and Altitude 243.84 m a above msl) to study the effect of irrigation schedule on growth, development, yield and yield attributes, total water use and water use efficiency of Cowpea. The lysimeters under experiment were filled with silty clay loam soil and were associated with 30±1.5, 60±1.5 and 90±1.5 cm water tables. Six irrigation treatments included T1 ( 3 cm irrigation water at IW : CPE ratio 0.3 by flood method) ; T2 ( 2 cm irrigation water at IW : CPE ratio 0.2 by Sprinkler method) ; T3 ( 3 cm irrigation water at IW : CPE ratio 0.2 by flood method) T4 ( 2 cm irrigation water at IW : CPE ratio 0.15 by Sprinkler method) ; T5 ( 3 cm irrigation water at IW : CPE ratio 0.15 by flood method) and T6 (2 cm irrigation water at IW : CPE ratio 0.10 by Sprinkler method) lysimeters associated with water table conditions. The results have shown that Plant height of cowpea var. Pant Lobia-1 was found to be maximum (55.71 cm) in T1 treatment where 6 irrigations were scheduled based on IW : CPE 0.3 using sprinkler method of irrigation .Number of leaves was significantly affected by various irrigation schedules, water table depths and irrigation methods. Maximum number of leaves (30.20, 29.78 and 29.40) were observed under irrigation at IW: CPE 0.3 , 60±1.5 cm water table depth and sprinkler method of irrigation respectively. Number of branches per plant was found significantly higher (1.12, 1.80 and 2.41 at 25, 50 and 75 DAS, respectively) under 60±1.5 cm water table observed . The plots receiving irrigations at IW : CPE 0.10 recorded significantly more number of branches per plant (1.08, 1.88 and 2.54 at 25,50 and 75 DAS respectively). The number of branches per plant was higher (2.41 at 75 DAS) through sprinkler method of irrigation. Maximum leaf area (18.83 cm2) was observed in 90±1.5 cm water table depth. Plots receiving irrigations at IW : CPE 0.10 recorded significantly higher leaf area of 17.72 cm2, while sprinkler method produced significantly maximum leaf area (18.42 cm-2). Days taken to 50 per cent flowering ranges from 48.83 to 38.83 among different irrigation combination treatments in lysimeters under water table condition. Results have also indicated that grain yield in lysimeters with 60 cm water table receiving 6 irrigations using IW: CPE as 0.3 was highest when irrigated with flood method, while the lowest grain yield was obtained in lysimeters associate with 30 cm water table and receiving one irrigation based on IW: CPE 0.15 using flood method. Highest water use efficiency (WUE) 1.73 kg ha-1cm-1 was obtained in lysimeters with 90 cm water table and receiving six irrigation by flood method as IW: CPE 0.3, while it was lowest (0.80 kg ha-1cm-1 ) in irrigation treatments receiving IW: CPE 0.15 using flood method under 30 cm water table. It is concluded from this study that among different irrigation treatments, irrigation schedule based on IW: CPE as 0.3 (six irrigations) was beneficial to the crop under medium water table (60 cm depth)conditions and flood method of irrigation was superior over sprinkler method for maximizing yield (1896.3 kg ha-1) of cowpea.

    Effect of P and Zn interaction on growth, yield, nutrient uptake and quality of maize (Zea mays L.) cv. HQPM-1 grown in mollisols
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-06) Abhishek Kumar; Singh, Veer
    A field experiment was conducted during kharif 2012 to find out the effect of P and Zn interaction on growth, yield, nutrient uptake and quality of maize (Zea mays L.) cv. HQPM-1 grown in mollisols at Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand. The treatments replicated thrice in a factorial randomized block design (F-RBD) and the experiment consisted of 10 treatments. Growth and yield attributing characters of maize significantly affected by application of various P and Zn levels which in turn increased grain and stover yields of maize. The plant growth parameters viz., plant height and number of leaves was observed highest with the application of 60 kg P2O5/ha along with 15 kg Zn/ha. Days to 50 per cent tasseling and silking were found minimum with the combined application of 15 kg Zn/ha and 60 kg P2O5/ha but anthesis silking interval (ASI) was found minimum under 10 kg Zn/ha and 90 kg P2O5/ha combination which consequently improved grain yield. Interaction effect of 10 kg Zn/ha along with 60 kg P2O5/ha significantly increased cob and grain yield by 59.3 and 48.1 q/ha, respectively, over control (36.3 and 25.0 q/ha). Combined application of 10 kg Zn/ha and 60 kg P2O5/ha in general increased the availability of soil nitrogen, phosphorus, and zinc. Total phosphorus and zinc uptake was found highest under treatment T10 and T5 respectively. Protein, tryptophan and lysine content in maize grain significantly affected with the Zn and P levels and highest values of 20.7, 0.29 and 1.15 %, respectively, were observed with 60 kg P2O5/ha and 10 kg Zn/ha combination. All the yield attributes attained the positive but no-significant correlation with soil pH, EC and available Zn but soil available P showed significant and positively correlation with grain yield (0.680*). Tryptophan and lysine contents of grain were significantly correlated with available P (0.799**, 0.792**), grain P (0.787**, 0.790**) and grain Zn (0.755*, 0.789**), respectively. Among all the treatments, combined application of 10 kg Zn/ha and 60 kg P2O5/ha (T6) was found superior over other treatments for most of the growth, yield and quality parameters.

    Effect of tillage and irrigation on growth and yield of wheat (Triticum aestivum l.) and their simulation studies using Ceres-Wheat Model
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-08) Mishra, Gaurav; Kushwaha, H.S.
    Field experiments were conducted in sandy loam soil at Norman E. Borlaug Crop Research Centre 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 2011-12 and 2012-13 to study effect of tillage and irrigation on growth and yield of wheat cv. UP-2565 and its simulation studies using CERES-wheat model. The experiment was laid out in 2 factorial RBD design with first factor i.e. three tillage practices viz. zero tillage (ZT), conventional tillage (CT) and deep tillage (DT) and second factor i.e. 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 observations were recorded on soil properties viz. infiltration rate, B.D, hydraulic conductivity, pH, EC, O.C, Available N, P and K, growth and development parameters viz. Plant height, LAI, root length density, no. of tillers, days to anthesis and days to physiological maturity, wheat (grain & biological) yield and yield attributes viz. spike length, no. of spike, grains per spike and 1000-grain weight under various tillage practices and irrigation schedules and simulation of some of these was also done using CERES-wheat model. Results indicated that tillage and irrigation significantly affect the infiltration rate, B. D., hydraulic conductivity, O.C. and available N in soil, while soil pH, EC, available P and K did not differ significantly with these treatments. Highest plant height 115.5 and 115.6 cm was recorded with DT and I5 in 2012-13, LAI 3.39 and 3.68 with DT and I4 in 2011-12, root length density 1.41 and 1.49 in DT and I5 in 2011-12 at 0-15 cm. Maximum no. of tillers and days to anthesis of wheat were recorded with CT and I5 while days to physiological maturity with DT and I5 during both crop seasons. Maximum spike length obtained in CT (7.85 and 7.79) and I4 (7.97 and 7.90), number of grain spike-1 in CT (34.2 and 29.0) and I5 (35.2 and 30.0) and 1000-grain weight in CT (38.0 and 40.0 gm) and I4 (39.4 and 40.6 gm) during both the crop seasons. The highest grain yields of 3438.3 and 3933.3 kg ha-1 respectively were recorded with CT in 2011-12 and 2012-13, while I5 (3602.7 kg ha-1) in 2011-12 and I4 (4173.6 kg ha-1) in 2012-13. Biological yield was maximum under DT (11700.0 kg ha-1) and I4 (11972.2 kg ha-1) during 2012-13. Significantly higher harvest index was obtained under DT (44.5%) and I1 (42.9%) in 2011-12. The analyzed data of experiments have shown that maximum observed LAI (3.80) was obtained during 2011-12 against simulated (3.24) in CTI4. Number of tillers m-2, days taken to anthesis and days to physiological maturity were underestimated during both the wheat crop seasons. Model simulated the grain and biological yield and higher efficiency (R2=0.72 for grain yield and R2=0.92 for biological yield) was obtained in 2011-12 in comparison to 2012-13. The harvest index of wheat was overestimated under some treatments during both the crop season. It is concluded from this study that in sandy loam soil the use of CT along with four irrigations (CRI + LT + F + M) gave maximum wheat yield. The CERES model simulated growth 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 2011-12 than 2012-13. The CERES wheat model has tremendous potential in predicting the yield of wheat crop under diverse agro climatic conditions especially in the locations where capital is the main constraint in conducting the field experiments and providing of the necessary lab facilities and lack of water for irrigation.

    Nutrient management in wheat under various tillage systems after transplanted rice
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-06) Mishra, Aakash; Singh, Sobaran
    Agricultural sustainability implies an increasing trend in per capita productivity to meet the present needs without jeopardizing the future potential. This demands an appropriate method of land and nutrient stewardship for the development of sustainable agricultural systems. Soil tillage and nutrient management influences agricultural sustainability through its effects on soil processes, soil properties, and crop growth & development. In this prospect the present investigation was carried out during rabi seasons of 2009-10 and 2010-11 at Norman E. Borlaug Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, entitled “Nutrient Management in Wheat under various Tillage system after transplanted Rice”. The experiment was laid out in split-plot design with three main-plot treatments i.e. three tillage methods (viz zero tillage, conventional tillage and subsoiling) and five sub-plots i.e. nutrient management options (viz, FP, GRD, STCR target @ 40 q ha-1, STCR target + FYM @ 10 tone ha-1, SSNM) with three replications. The observations were recorded on growth and physiological parameters (Plant height, flag leaf area and relative leaf water content), yield (grain, straw and biological) and yield attributing observations (spike length, no. of spike, grains per spike and thousand grain weight) and nutrient study of soil and plants (available N, P and K, its uptake and total uptake) under different tillage and nutrient management options. The tillage methods and nutrient management options had significant influence on yield & yield attributing characters and nutrient study of soil and plants. The average grain, straw, biological yield and plant nutrient uptake in wheat showed highest records under conventional tillage method and STCR target + FYM nutrient management option. Economics of an experiment showed that the cost of cultivation was higher under subsoiling and GRD treatment, whereas, gross and net monetary returns were higher under conventional tillage and STCR target + FYM and SSNM treatment respectively. The Benefit: Cost ratio was also higher under conventional tillage and STCR target + FYM nutrient management treatment.
