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.

    Wear characteristics and material Composition of ADI-III rotavator blades
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Arya, Rajat; Pateriya, R.N.
    Rotavator is an efficient tillage implement used for rapid seed bed preparation and is an energy and time efficient equipment for different soils compared to all other conventional tillage implements. The primary cause that limits the persistence of rotavator is wear of rotavator blades which are different for different types of blades. This work was undertaken to study the material composition and wear characteristics of ADI-III Rotavator blades which were made by austempering heat treatment process done over cast iron. The objective was carried out by means of elemental analysis and identification of wear pattern of rotavator blades with increase in operational time and the study was compared to imported and indigenous rotavator blades namely, Jumbo make and Jay Bharat make. The results indicated that change in material compostion responsible for wear characteristics of blades was minimum for ADI-III rotavator blades. Iron and Carbon contents were decreased from 84.33 and 5.30 % to 72.4 and 4.20 % respectively. Minimum weight loss of 140.2 g was observed in ADI-III, followed by 159.21 g in Imported and maximum weight loss of 219.68 g was recorded in Indigenous rotavator blades after 100 hours of actual field operation. The wear rate for ADI-III blades was 1.402 g/h after 100 hours of operation which was minimum in comparison to other rotavator blades. It was found that blade section of rotavator blade was most prone to wear and reduction in thickness at blade section for ADI-III, Indegenous and Imported rotavator blade was 2.29, 3.59 and 3.29 mm respectively.
