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.

    Influence of temperature on decomposition of wheat straw and nutrient release in mollisols
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-08) Joshi, Ganga; Mishra, B.
    A laboratory experiment was conducted to study the influence of temperature on decomposition of wheat straw and nutrient release in Mollisols. For this study representative samples of three soils viz. Phoolbagh clay loam, Haldi loam and Patherchatta sandy loam were taken and wheat straw was applied @ 4.544 g/kg soil. The soils were incubated at 15, 25 and 35°C for 90 days. The evolution of carbon dioxide from soils was measured quantitatively following the alkali trap method. The soils differed significantly with regard to CO2 evolution. Haldi loam showed the highest CO2 evolution while Patherchatta sandy loam recorded the lowest, irrespective of temperature. The rate of CO2 evolution from all the soils was highest during the first six days of incubation and lowest at the end of incubation period. The CO2 evolution at 35°C was significantly greater than at 25 and 15°C at all dates of observation. At the end of incubation period in Phoolbagh clay loam 24.6, 38.4 and 59.6 percent carbon from added wheat straw was lost at 15, 25 and 35°C, respectively. In Haldi loam the corresponding values of wheat straw carbon loss was 22.4, 37.9 and 52.7 percent and in Patherchatta sandy loam 21.1, 31.8 and 45.3 percent, respectively. Out of two mathematical models viz. power function model and first order kinetic model the power function model showed better fitness with wheat straw carbon loss data with lower RMSE and higher R2 values than first order kinetic model. The half life of wheat straw in Mollisols varied from 371 to 426 days at 15°C, 130 to 238 days at 25°C and 50 to 95 days at 35°C. After decomposition of wheat straw in soils available P and K content increased moderately whereas, the available N level decreased over initial level. The increase in available P and K of the soils due to wheat straw was more at 35°C than at 25 and15°C. It was concluded that decomposition of wheat straw in the soils was slow and temperature dependent. The rate of decomposition followed power function model. Available P and K status of the soils were moderately increased by wheat straw incorporation.

    Integrated nutrient and water management under drip irrigation system for litchi orchard
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-01) Joshi, Ganga; Srivastava, P.C.
    The present investigation was carried out during 2006-07 and 2007-08 at Horticultural Research Centre, Patharchatta, G.B. Pant University of Agriculture and Technology, District Udham Singh Nagar (Uttarakhand), to study the effect of integrated nutrient and water management under drip irrigation system in a six year old litchi (cv. Rose scented) orchard, planted at 5m distance in square geometry. The treatments comprised the combinations of four levels of fertilizer viz., no fertilizer and 75,100 and 125% RDF (Recommended Dose of Fertilizer); one level of conventional and three levels of drip irrigation maintained at 50, 75 and 100% of estimated irrigation water requirement and two levels of mulching viz., without mulch and with black polythene mulch. The maximum plant height, plant spread and tree volume were recorded with the use of black polythene mulch + drip irrigation at 100% of estimated irrigation water requirement + 125%RDF. Both at the stages of maturation of September flush and 50% flowering, the maximum contents of N, S, B and Zn in leaves were recorded with the application of black polythene mulch + drip irrigation at 100% of estimated irrigation water requirement +125%RDF while the maximum contents of P and K were noted with black polythene mulch + drip irrigation at 75% of estimated irrigation water requirement +100%RDF in both the years. The minimum fruit drop and fruit cracking and maximum fruit yield/tree and better fruit quality were recorded with black polythene mulch + drip irrigation at 100% of estimated irrigation water requirement +100%RDF. As regards the effects of tissue age on the nutrient content of leaves, it was noted that NPK contents were higher in the immature tissue as compared to the matured leaves while the contents of S, B and Zn were higher in matured leaves. The maximum contents of available N, P, K, S, B and Zn in soil were noted under treatment receiving the black polythene mulch + drip irrigation at 100% estimated irrigation water requirement +125%RDF. Application of black polythene mulch with drip irrigation maintained an optimum temperature during winter and summer upto 15 cm soil depth and increased the microbial biomass carbon.
