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.

    Effect of shade stress on physiological, biochemical and agronomic traits of various rice (Oryza sativa L.) genotypes
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-09) Bhatt, Priyanka; Shankhdhar, S.C.
    Rice (Oryza sativa L.) is the world single most important food crop, being the primary source for more than one third of the world population. Rice is not only the most widely used food crop by a third of the population of the world, but it has also been established as the model monocot plant for study. Rice is extremely sensitive to the environmental factors as, solar radiation, temperature, rainfall, relative humidity and wind. Light is one the most important factor that determines plant growth and development. In some areas of the world with continuously cloudy weather or rainfall, rice yields can be reduced by 30% to 50% indicating that low light is an indispensable problem for rice production. For the Morpho - physiological, biochemical and agronomic responses of rice (Oryza sativa L.) under low light stress condition, a field experiment was conducted in A2 block of Norman E. Borlaug crop research center, G.B. Pant University of Agriculture and Technology, Pantnagar during Kharif season 2020 with twenty one rice genotypes namely, IET 27537, IET 27547, IET 28264, IET 28276, IET 28281, IET 28283, IET 28286, IET 26692, Pooja, IET 26744, Swarnaprabha, IET 29025, IET 29026, IET 29027, Gayatri, IR-8, IET 29029, IET 29030, IET 29031, IET 29032, IET 29033. Swarnaprabha was taken as a check variety among all the parameters. All twenty one genotypes were transplanted in two blocks control i.e., normal light and treatment i.e., which was imposed with low light stress by covering the blocks with 50% shade net supported by bamboo sticks and both the entry ends were left open for proper ventilation. Among the twenty one genotypes only five genotypes attained maturity specifically, IET 28281, IET 29025, IET 29027, Gayatri, and Swarnaprabha. Several parameters namely, plant height, tiller number, leaf area index, leaf dry weight, stem dry weight, total dry matter, panicle number, panicle weight, spikelet number, filled grains, thousand grain weight, grain yield, harvest index, chlorophyll content, carbohydrate content and malondialdehyde content were recorded for the rice genotypes and it was recorded that except plant height, leaf area index, chlorophyll content all the parameters significantly reduced under low light stressed conditions. Due to some genotypic variations some genotypes were regarded as the tolerant genotypes and some as the susceptible genotypes. The low light tolerant genotypes performed better in terms of grain yield, harvest index in comparison to less tolerant and susceptible genotypes. In the present study, genotype IET 28281 was found highly tolerant to low light stress followed by moderately tolerant genotype IET 29027 and the genotype IET 29025 was found least tolerant to low light stress. A positive correlation of most of the morpho-biochemical and yield parameters with grain yield at control (normal) light conditions and a negative correlation of these parameters were found at low light conditions.
