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 of bactericidal activity in pyrolyzed bio-oil against plant pathogenic bacteria
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-12) Baghel, Megha; Verma, A.K.
    Pyrolyzed bio-oils from pine needle (Pinus roxburghii), corn cob (Zea mays) Bambusa balcooa and Dendrocalamus hemiltonii was used to evaluate the antibacterial activity of different plant pathogenic and non-pathogenic bacteria Xanthomonas axonopodis, Xanthomonas campestris, Xanthomonas oryzae, Ralstonia solanacearum,and Pseudomonas fluorescens. The pine needle and corn cob bio-oil have approximated 50% content phenolic compounds. The bio-oil from these plant residues were prepared by pyrolysis. Three different formulations were prepared by adding (30%,40% and 50%) bio-oil, ethanol as solvent, saponin as surfactant and aqueous phase of bio-oil was used to make up the volume. The pine needles bio-oil formulations showed maximum zone of inhibition 18.49±0.092mm against Xanthomonas axonopodis at formulation F2. The in-corn cobbased formulation F2 showed 17.6±0.353mm zone of inhibition against Xanthomonas oryzae. Hence pine needle and corn cob-based formulation F2 was found effective for the antibacterial activity. The nano-emulsion of these formulation F2 were prepared after dilution up to 10-4 times and characterization by DLS and FTIR. The nanoparticles were homogeneously mono dispersed in the sonicated pine needle bio-oil formulation (dilution10-1) sample, that had a core diameter of 237.5 nm. While the corn cob-based formulation F2 had core diameter 667.3 mm. The FTIR data of nano-emulsion of both formulations were showed a characteristics difference after sonication. The bactericidal mechanism was identified by membrane permeability and membrane integrity test. The integrity and cell membrane permeability of pine needle bio-oil based formulation was found to be higher in case of Xanthomonas axonopodis, while that of corn cob bio-oil based formulation was found to be higher against Xanthomonas oryzae. These formulations were tested in field on Xanthomonas axonopodis infested soyabean plants. After 20 days of inoculation of Xanthomonas axonopodis soyabean plant the formulation F2 of pine needle-based formulation and corn cob-based formulation was sprayed on infested plant. It had been found that due to the slightly acidic nature of formulation the leaves were inflamed.
