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 main line for centre pivot sprinkler system
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-09) Aanchal Kumari; Singh, R.P.
    The main line is an important component as a pipeline of the centre pivot sprinkler irrigation system. in this study optimization model is developed for designing a multi-diameter main line to operate the nested centre pivot system. the optimization model minimizes the total annual cost as the sum of fixed and energy costs of the system with constraints imposed according to design requirements. the annual fixed cost includes the initial cost of the pipeline multiplied by the capital recovery factor. The annual energy cost is computed on the basis of frictional head loss of the pipeline and other economic factors. the sum of frictional head loss and elevation head in each section of the pipeline is computed and the resultant is used as the basis of obtaining pressure head variation at the operating points of the main line. frictional head loss computation in the main line was performed by the hazen-william’s formula for different cases of three, four and five pipe sizes combinations. the constraints are imposed in the form of pressure head at the critical point and total length for each section of the pipeline. a standard design problem was solved with the help of lingo 10.0 for verifying the results as well as to show the applicability of the developed optimization model considering the combinations of different pipe sizes. the effect of pressure head at the critical operating point was analyzed on the optimal solutions. further, a greater number of pipe sizes combination resulted in the lower cost. all the combination of pip sizes resulted in different maximum optimal cost for the same value of pressure head at the critical point of main line. in the initial range of the pressure head at the critical operating point, the pressure heads at the operating points of the main line were having the same value. it was found that optimization model resulted in the lower optimal cost than the graphical method. also, optimization model resulted in about 35 %, 48 % and 50 % for the three, four and five pipe sizes combination respectively than the graphical method with lesser pressure head variation at the operating points.
