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 soil amendments on runoff, sediment yield, biomass, soil physico-chemical properties and loss of major nutrients from sloping land under natural and simulated rainfall conditions
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-06) Kushwaha, Daniel Prakash; Anil Kumar
    In this research, experimental study was made in three successive trials, viz. first and second trials were conducted under natural rainfall conditions in Mollisols soils of Pantnagar in the foothills of North Western Himalayas during monsoon season of 2018 and 2019, respectively; and the third trial was conducted in simulated rainfall conditions just after completion of natural experiments. During first trial under natural conditions, a pre-determined dose of soil amendments was applied, while in second trial an increased dose of amendments was applied to check their incremental effect. Three soil amendments viz. biochar, anionic PAM and gypsum were used to fix six treatments: control (C); gypsum (G); biochar (B); gypsum and polyacrylamide (G+PAM); biochar and polyacrylamide (B+PAM); and biochar and gypsum (B+G) and each treatment was replicated thrice on plots of size 3m × 3m using randomized block design on uniform land slope of 12%. Hypothesis was whether six treatments could reduce surface runoff, sediment yield, loss of major soil nutrients (N, P and K), and maintain and improve soil physico-chemical properties and above- and below-ground biomass or not? (B+PAM) treatment of second trial, in which biochar was applied @ 1500 g/m2 and PAM was applied @ 4 g/m2, was found to be the best treatment under natural conditions. Therefore, this particular treatment was considered again under simulated rainfall conditions, but this time variable land slopes of 0%, 6%, 12%, 18%, and 24% on plots of size 1m × 3m and variable application rates of amendments along with five simulated rainfall intensities viz. 7.06, 9.07, 11.05, 12.97 and 14.96 cm/h were applied. Trial under simulated rainfall conditions was completed in four consecutive stages, mainly control (no amendments), biochar mixed with soil @ 1000 g/m2, 1500 g/m2 and 2000 g/m2. In each stage, PAM was applied @ 3, 4 and 5 g/m2. Available N-P-K losses, biochar loss, sediment yield and runoff were taken into account in simulated rainfall conditions. In simulated experiment, low dose of anionic PAM as 3 g/m2 (0.03 t/ha) in all conditions and high dose of biochar as 2000 g/m2 (20 t/ha) was found to be acceptable for reduction of runoff, sediment yield and major nutrient losses. In the loss of biochar study, 1500 g/m2 (15 t/ha) was found acceptable instead of high dose 2000 g/m2 (20 t/ha) for reduction of biochar loss. In this study, three reasonable model scenarios of sediment yield, nutrient loss and biochar loss were also developed using the experimental data of both conditions. For these model scenarios, four modeling techniques viz. MLP-ANN, SVM-RKF, SVM-LKF and MLR were used. Under natural conditions, five variables of the best treatment viz. rainfall, runoff, sediment yield, biochar loss and nutrients (N, P and K) loss were selected, while under simulated conditions, seven variables viz. rainfall, runoff, sediment yield, biochar loss, nutrients (N, P and K) loss, application rate of amendments, and land slope were selected for the development of model scenarios. On the basis of modeling results under natural and simulated conditions, it was found that SVM-LKF model performed well in comparison to other models in simulating event based data.
