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.

    Optimal design of sprinkler laterals based on overlapped pattern and set time of irrigation
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-07) Chaudhary, Aakansha; Singh, R.P.
    In this study optimization models were developed for designing a single, double and multi-diameter sprinkler lateral lines for various values of uniform upward and downward slopes. It is assumed that a set of suitable pipe diameters as 𝑑1 𝑑2 …………𝑑𝑝 in ascending order are available to be selected completely for each section of lateral pipeline connecting outlets. The optimization model has to select only that diameter out of the available diameters for each section which will result in the minimum total cost. The energy cost of operating lateral line is added with the fixed cost of the lateral line to obtain the total cost of the lateral line. The main constraints imposed in the optimization model are the length constraint, allowable frictional head of the lateral line for acceptable pressure variation in form of energy conservation and distribution coefficient to consider desired value of uniformity coefficient. The equations related to discharge pressure head relationship, adequacy of irrigation, application rate and set time are also written as constraints along with non negative length constraints. The Hazen-Williams equation with multi-outlet factor was used to computing the frictional head loss in single, double and multi-diameter pipelines respectively. The applicability of the optimization models was illustrated by solving different design problems using LINGO 17.0. The optimal solutions obtained are compared by already available solutions. The effects of slopes, fraction of area adequately irrigated, and depth of irrigation on optimal solution were studied. The single pipe size lateral line with bigger diameter was resulting in lesser total cost than the smaller diameter. The pressure variation of the bigger pipe size lateral was lesser with higher initial cost whereas the smaller diameter lateral line is having lower initial cost with higher pressure variation. The optimal design of two and three pipe sizes lateral lines were resulting in lower total cost and pressure variation for the pressure variation constraint as less than equal to 20 % than the pressure variation constraint as equal to 20 %. However, the selected lengths with their corresponding diameters were having higher initial cost due to bigger pipe sizes with more number of pipe sizes than smaller pipe sizes with lesser number of pipe sizes.
