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.

    Biodegradation of s-triazine herbicide: Atrazine by native soil bacterial isolates employing nanoparticles
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-12) Hina Khatoon; Rai, J.P.N
    In present study a popular herbicide viz. atrazine degradation potential of two soil bacterial strains isolated from Crop research centre at G.B.P.U.A. & T., Pantnagar, Uttarakhand in year 2017 was investigated under optimized laboratory conditions. Based on cultural,morphological, biochemical and 16S rRNA gene sequencing, these bacterial isolates were identified as Bacillus badius ABP6 and Bacillus encimensis ABP8. All the isolates performed best at pH 7, 30ºC temperature and 150 rpm shaking speed. Supplementation of additional carbon and nitrogen sources in liquid medium enhanced degradation rate of atrazine by bacterial isolates. In an in vitro comparative biodegradation study conducted in minimal medium, soil slurry and soil microcosm, maximum degradation (84.80%, 86.40% and 87.70%) of atrazine was observed in treatment inoculated with bacterial consortium after 20 days. The atrazine degradation kinetics indicated that the degradation rate constant has ranged from 0.01 to 0.09 (minimal medium), 0.011 to 0.095 (soil slurry) and 0.012 to 0.138 (soil microcosm) for all the treatments. Immobilization of bacterial cells on sodium alginate beads, sugarcane baggase, nanozeolite and synthesized α-Fe2O3 nanoparticles showed maximum atrazine degradation in minimal medium, soil slurry and soil microcosm under consortium treatment, after 20 days as compare to free bacterial cells. SEM analysis revealed successful immobilization of bacterial cells on different immobilizing carriers. Rhizoremediation study conducted in maize (Zea mays) rhizosphere, further confirmed the siginificance of bacterial isolates in atrazine degradation. All bacterial treatments resulted in enhancement of maize growth response, chlorophyll and protein content, significantly over control. However carotenoid content was found to decrease in response to inoculation. Atrazine dissipation in soil and accumulation by Zea mays was observed in different time period and maximum accumulation was observed in roots while least was in leaves for all treatments. As compared to monoculture, consortium performed better in case of all the experiments conducted. HPLC, FTIR and GC-MS analysis confirmed the formation of metabolites as a result of biodegradation. Utilization of dynamic microorganisms is an efficient and economical strategy, while microbial immobilization gives a breakthrough in the restricted application of microbes in in-situ. The study clearly demonstrated that B. badius ABP6 and B. encimensis ABP8 were able to metabolize atrazine effectively and thus could be employed profitably for field scale bioremediation technology.
