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.

    Modeling and optimization of process parameters for hot air drying of banana (Musa paradisiaca L.) slices
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-08) Dinkar, Vairat Amita; Pandey, R.K.
    The Banana (Musa paradisiacal L.) is a crop of tropical climate and is grown for its fruit, fiber or foliage. Green banana is perishable and deteriorates after harvesting. Drying prolongs the shelf life of banana. The hot air drying characteristics of green banana slices were studied at drying temperature (40-800C), air velocity (1.5-5.5 m/s) and slice thickness (2-6 mm) in the laboratory scale hot air dryer. Drying was found to occur in the falling rate period only. Higher drying rate were observed with the higher temperature level and minimum level of slice thickness. Drying rate increases with increase in air velocity upto 3.5 m/s after that there was no profound effect on drying rate. The drying behavior of the banana slices was mathematically analyzed using models namely page’s, exponential and logarithmic model. The experimental validity of models were done on the basis of maximum R2 and minimum SEE, and RMSE. The page’s model described the drying behaviour of banana slices better as compared to exponential and logarithmic model. The results reveled that, the temperature, air velocity, slice thickness had significant effect on various quality parameters of dried banana slices viz. rehydration ratio, hardness, shrinkage, ascorbic acid and color whereas carbohydrate and ash content had non-significant effect. The optimum level of independent variables for banana drying obtained by using numerical optimization of multiple responses viz. drying time, rehydration ratio, shrinkage, hardness, ascorbic acid and L and b value were temperature-600C, air velocity- 3.5 m/s and slice thickness- 2mm. These optimum values are recommended for hot air drying of banana.
