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.

    Performance comparison of solar cooker using different phase change materials during off sunshine hours

    The continuous increase in the level of greenhouse gas emissions and the increase in fuel prices are the main driving forces behind efforts to more effectively utilize various sources of renewable energy. In many parts of the world, direct solar radiation is considered to be one of the most prospective sources of energy. Energy requirement for cooking accounts for 36% of total primary energy consumption in India. Hence, there is a critical need for the development of alternative, appropriate, affordable mode of cooking for use in developing countries. However, the large scale utilization of this form of energy is possible only if the effective technology for its storage can be developed with acceptable capital and running costs. Solar cooker is the best way to utilize solar energy. In the present work thermal performance of a box type solar cooker has been evaluated according to the bureau of Indian standard (BIS). The BIS suggested two test for evaluation of thermal performance. The first test is stagnation test for evaluation of first figure of merit F1.The second test is full load test for the determination of second figure of merit F2. The first figure of merit is obtained by conducting the stagnation temperature test without load for empty box type solar cooker. The first figure of merit is the ratio of optical efficiency to heat loss factor. The second figure of merit is obtained by sensibly heating a known amount of water and it is a measure of heat exchange efficiency factor of a box type solar cooker. The variation in second figure of merit is also studied by increasing load and number of pots. It is found from experimental study that second figure of merit increases with load and number of pots. The value of figure of merit imply that the cookers are identical and satisfy BIS standard. The performance comparison of solar cooker using different phase change materials during off sunshine hours is main emphasis of the present experimental study. Cookers are also studied using modified finned cooking vessel. Three different phase change materials paraffin wax, stearic acid, lauric acid are selected. It is found from experimental studies that finned cooking vessel increases efficiency and reduces the cooking time. Paraffin wax is best phase change material to store latent thermal energy during sunshine hours and to retrieve back its conserve energy to thermic fluid water during off sunshine hours.
