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.

    Comparative evaluation of calibrated temperature-, and radiation-based ET0 equations developed for semi-arid climatic conditions based on standardized FAO56-PM model
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-08) Bind, Shyam Murari; Tomar, A.S.
    The present study was undertaken to calibrate, validate and evaluate different temperature-, and radiation-based ET0 equations on daily, weekly, monthly, and seasonal (crop and weather) basis for semi-arid climatic conditions of Parbhani and Udaipur in comparison to standard FAO56-PM model with two specific objectives as, (i) to calibrate, validate and evaluate performance of various temperature-, and radiation-based ET0 equations in comparison to FAO56-PM model, and (ii) to calibrate and evaluate performance of all considered ET0 equations by using MicrosoftTM Excel Solver in comparison to FAO56-PM model. In this study, individual year was converted into 52 Standard Meteorological Weeks (SMWs), 12 months, three crop seasons (rabi, zaid and kharif) and three weather seasons (winter, summer and monsoon) in tune with CWS-1 format suggested by Indian Meteorological Department, Pune. The MicrosoftTM Excel was used as computing tool for conducting analysis and draw fruitful inferences from them. Prior to analysis, quality control of daily weather was also ensured by detecting missing data and outliers. The results showed that at all timescales, almost all calibrated ET0 equations performed well and extended better results in comparison to their original versions. Further, it was found that, calibrated Hargreaves-Samani M3 equation was found best at both places on daily, weekly, monthly, and weather season basis, while Hargreaves-Samani M1 performed best at both places on crop season basis. Among temperature-based ET0 equations, Romanenko equation was found worst at all timescales for both the places. Among radiation-based ET0 equations, Valiantzas (2) equation performed best while Irmak-Rn ET0 equation performed worst at all timescales for both places. Determination of calibration coefficient of different temperature- and radiation-based ET0 equations by using MicrosoftTM Excel Solver was found at-par in comparison of tedious and time-consuming MicrosoftTM Excel utility.
