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.

    Studies on dynamic balancing of thresher drum and its effect on vibration and power consumption
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-08) Negi, Rohit; Arun Kumar
    Farm mechanization and adoption of latest techniques have played an important role in increasing the agricultural production, due to which the number of agricultural equipment and machines has increased. One of the agricultural machines is thresher which is used for loosening and detaching the grains from ear heads. Threshers have played a special role in the post-harvest operations of the crop which results in the increase in production. With the functional design, there is a need of improvement in the dynamic performance of the thresher. To improve the dynamic performance of thresher, dynamic balancing of the thresher drum was performed. Dynamic balancing was conducted on thresher drum of a small multi crop thresher and a small wheat thresher. For dynamic balancing of thresher drum a set-up was developed. The vibration amplitude and power consumption of thresher was measured and compare before and after the balancing of thresher. The vibration amplitude and power consumption were analyzed at five levels of cylinder speed (300 rpm, 360 rpm, 420 rpm, 480 rpm and 540 rpm) in multi crop thresher and at four levels of cylinder speed (720 rpm, 870 rpm, 1080 rpm and 1160 rpm) in the wheat thresher on load and no load conditions. It was observed that the vibration amplitude and power consumption reduced after the balancing of thresher drum of both the threshers. In multi crop thresher the maximum reduction in vibration amplitude on no load and on load was noted as 41.62% at the frame adjacent to the bearing of the thresher drum shaft (LM4) and 38.38% at the second upper corner of the frame supporting the thresher drum (LM2), respectively. In wheat thresher the maximum reduction in vibration amplitude on no load and on load was noted as 52.10% at the third upper corner of the frame of thresher (LW3) and 58.33% at feeding chute (LW6). Maximum reduction in power consumption on no load was measured 6.08% and 7.76% in multi crop and wheat thresher, respectively.

    Design and development of rotary plough for hills
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-08) Bist, Vijendra Singh; Singh, Jayant
    By keeping in mind the problem faced by the farmers in hilly areas and to promote farm mechanization a new type of rotary plough is designed. The designed rotary plough has straight knife edge blades which were attached on circular flange. Power from main engine shaft is transmitted to the rotary blades by using bevel and spur gear transmission system. The effect of forward speeds, depth of operation and soil moisture content on fuel consumption, actual field capacity, field efficiency, energy required per unit area and total cost were studied. Two soil moisture content (12.73 and 14.56 %), two forward speeds (1.5 and 2 km/h) and three depths of operation (5.5±0.5, 7.5±0.5 and 9.5±0.5 cm) have been chosen. The results showed that, the minimum value of fuel consumption was 0.98 l/h and recorded when the forward speed was 1.5km/h at depth of 5.5±0.5 cm and soil moisture content 14.56 %. The minimum value of effective field capacity was 0.038 ha/h when forward speed was 1.8 km/h, soil moisture content 12.73% and under depth of operation 9.5±0.5 cm. The highest field efficiency was 86.90% with 1.5 km /h forward speed at 5.5±0.5 cm depth of operation mm and soil moisture content 14.56%. The lower value of total cost was 2740 ₹/ha and was obtained when the forward speed was 2 km/h at 5.5±0.5 cm depth of operation and soil moisture content 14.56 %. The lowest value of energy required per unit area 181.47 MJ/ha was obtained at 2 km/h forward speed and soil moisture content of 14.56% at 5.5±0.5 cm depth of operation.
