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.

    Sediment outflow for varying intensity-duration storms and rainfall commencement period under simulated rainfall conditions
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-05) Bansal, Gireesh Kumar; Akhilesh Kumar
    The present study was carried out with the objective to observe the sediment outflow for variable intensity-duration storms and also for different rainfall commencement periods at selected land slopes under simulated rainfall conditions by using a rainfall simulator of size 10 m 1.4 m and a hydraulic tilting flume of size 10 m 1.2 m 0.5 m. with the locally available soil material collected from Crop Research Centre (CRC), Pantnagar. In this study, three rainfall intensities viz. 9.0 cm/h, 13.2 cm/h and 17.0 cm/h for three selected rainfall durations of 10 min, 20 min and 30 min were considered at 0 %, 2 % and 4 % land slopes in case of isolated storms. The complex storms were created by combining two and three rainfall intensities for total 30 min storm duration. The timing of occurrence of these intensities was regulated in a way such that different rainfall patterns viz. advanced (ARP), delayed (DRP), intermediate-I (IRP-I), intermediate-II (IRP-II) and uniform (URP) were obtained. Apart from the above, attempts were also made to observe and quantify the effects of time gap between two successive rainstorms called as “rainfall commencement period” over sediment outflow behaviour at different land slopes. For this purpose, an isolated storm of 13.2 cm/h rainfall intensity for 10 min duration was applied for selected rainfall commencement period of 0 h, 1 h, 3 h, 6 h and 12 h at each of the selected land slopes. The total runoff volume was observed to be almost the same for a particular rainfall input at every land slope. However, the distribution pattern of runoff was observed to be different with the change in land slope. The average sediment concentration was found to be increasing with the increase in land slope in every case but did not provide any definite trend with the rainfall intensity, duration, rainfall pattern and rainfall commencement period. The rate of sediment outflow was found to be increasing with the increase in land slope as well as in rainfall intensity but found to be decreasing with the increase in rainfall duration. However, the total sediment outflow increased with the increase in land slope, rainfall intensity and rainfall duration in case of isolated storms. In case of complex storms CS2RI and CS3RI, the sediment outflow rate and total sediment outflow did not provide any definite trend with the rainfall distribution pattern. However, in general both of them were found to be increasing with land slope under a particular rainfall distribution pattern. The sediment outflow rate as well as total sediment outflow were found to have a decreasing trend with the increase in rainfall commencement period at a particular land slope but found to be having an increasing trend with land slope for a given rainfall commencement period. Mathematical relationships were developed relating average sediment concentration and sediment outflow rate with rainfall intensity, land slope, rainfall duration and rainfall commencement period as per the case. It was observed that log transform values of average sediment concentration and sediment outflow rate had a good correlation with rainfall intensity land slope, rainfall duration and rainfall commencement period. The correlation coefficient of developed models was found to be more than 90% in genera
