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 pipe networks for microirrigation system
    (2013-12) Manyazew, Boja Mekonnen; Singh, R.P.
    Microirrigation is one of the latest innovations for applying water and represents a definite advancement in irrigation technology. The high initial cost is the major hindrance in popularizing this irrigation system. The main objective of this study is to develop optimization models for designing different types of pipe networks of microirrigation subunits. This thesis presents the developments of optimization models to design pipe networks of single size single lateral and manifold, two pipe sizes single lateral and manifold, single size paired laterals and manifolds, two pipe sizes paired laterals and manifolds along with submain and mainline. The pipeline hydraulics and economic parameters related to the annual energy cost of operating the system have been incorporated in the models by using appropriate formulae. Linear and nonlinear optimization models have been developed for designing pipe networks of microirrigation subunits. The objective functions are formulated to minimize the total annual cost per unit area formed by laterals and manifold of a subunit. The optimization models design the fixed and computed subunit sizes along with corner and central feeding of manifolds by imposing appropriate constraints of lengths, allowable pressure head variation, conservation of energy and nonnegative. The sensitivity analyses for time of irrigation, irrigation interval, emitter discharge, emission uniformity, allowable pressure head variation, slope of the land and number of subunit were carried out to see the effect on optimal solution of the design. The enumeration method was used to check the validity and efficiency of the developed optimization model. The applicability of the developed optimization models is shown by solving design examples using LINGO solver. The developed optimization models result in economical and efficient design of pipe networks over enumeration method and can be easily used for designing pipe networks for any conditions of microirrigation subunits.
