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.

    Comparative study of chemically and green synthesized sulphur nanoparticles
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-03) Himanshi; Joshi, Deepika P.
    The present work is a comparative study of chemically and green synthesized sulphur nanoparticles. In the chemical method, sodium dodecylbenzene sulphonate (SDBS) has been used as a capping and stabilizing agent, while in green synthesis, Catharanthus roseus, Aloevera, Ocimum basilicum and Syzygium cumini leaves extract have been used as a surfactant. Citric acid and oxalic acid have been used to provide the acidic medium throughout the process. A total of eight combinations have been used to find the best among green synthesized sulphur nanoparticles. UV-Vis, XRD, FTIR, SEM and EDX characterization techniques have been used to study the attributes of sulphur nanoparticles. It has been found that sulphur nanoparticles synthesized using Syzygium cumini leaves extract in both acidic mediums are smaller, uniformly distributed and spherical, but the sulphur nanoparticles synthesized using oxalic acid have the smallest crystalline size. Further, a comparative study has been carried out between the chemically synthesized sulphur nanoparticles and green synthesized sulphur nanoparticles using an appropriate combination, which revealed that green synthesized sulphur nanoparticles are more crystalline and have a small crystalline size with high crystallinity index. Thereafter, the reducing agent has been replaced with green acid(Lemon juice) and a comparative study has been carried out in combination with SDBS and Syzygium cumini leaves extract. Syzygium cumini leaves extract shows better capping and stabilizing activity with lemon extract as compared with SDBS. Pure green synthesized sulphur nanoparticles are small and evenly distributed. The study has been extended to assess the comparative antifungal efficacy of chemically and green synthesized sulphur nanoparticles. It has been observed that sulphur nanoparticles synthesized using pure green extract(Syzygium cumini and lemon juice) are more compatible with the biological system in comparison to all other combinations.Therefore these green synthesized sulphur nanoparticles can be the better alternatives for getting disease free and high- yield crops without compromising with the natural habitats.

    Theoretical study of thermal expansion and bulk modulus of nanomaterials
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-07) Himanshi; Munish Kumar
    A simple theoretical method is developed to study the effect of temperature on thermal properties viz. volume thermal expansion and bulk modulus of nanomaterials by modifying the He and Yan Model. We have considered seven nanomaterials viz. silver (20nm), aluminium (40), selenium (19nm), zirconia (8nm), zinc oxide (25nm), nickel oxide (25 nm) and titanium dioxide (35nm). The results are compared with the available experimental data for volume thermal expansion of nanomaterials. The good agreement between theoretical and experimental results supports the validity of the model. It should be reported that the experimental data of temperature dependence of bulk modulus are not available. So, we are reporting our computed results. Since our result depends on computed value of V/V0, which are in good agreement with experimental data. Thus the results of bulk modulus may be regarded as reliable. The effect of shape and size is also studied. We have considered the size 10nm and 90 nm to compute our results and observed that the volume thermal expansion decreases with the increasing size. We have also studied the effect of shape of nanomaterials on volume thermal expansion and bulk modulus. It has been observed that the value of V/V0 is maximum in case of spherical nanomaterial followed by nanowire and nanofilm.
