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.

    Investigation of structural, optical and ferroelectric behaviour of NIFE2O4 and YMNO3 composites
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-09) Joshi, Hema; Dixit, Gagan
    Magnetoelectric multiferroic materials are characterized by the property of ME coupling which allows the manipulation of magnetisation in these materials by applying an external electric field and vice-versa. Due to this property, multiferroic materials are widely used in technological applications like sensors, memory devices, microwave applications, solar cells, energy harvesting etc. These materials are being continuously studied to obtain better magnetic and electric properties and higher value of ME coupling coefficient. In the present work composites of NiFe2O4 (NFO) and YMnO3 (YMO), xNiFe2O4/(1-x)YMnO3 [x = 0.25 and 0.50] have been prepared by mixing NiFe2O4 and YMnO3 powders. Different measurement techniques; XRD, UV-Vis spectroscopy, P-E loop measurement and VSM have been used to study structural, optical, ferroelectric and magnetic properties of the composites and the pure samples. Coexistence of both the ferrite and ferroelectric phase in the composites was confirmed by XRD analysis. Variation in lattice constant and crystallite size confirm that NFO lattice is more susceptible for change in structural parameters than the YMO lattice. The band gap values for all the samples determined using UV-Vis spectra varied in the range 1.4 to 1.75 eV. Saturation magnetization for pure NiFe2O4 was found to be highest and its value was 46.17emu/g. The composites show ferromagnetic ordering with saturation magnetization decreasing with increase in concentration of ferroelectric phase in the composites. P-E hysteresis loop measurement indicates resistive type behavior of composites as well as pure YMnO3. High conductivity of the samples was the reason for this poor ferroelectric nature of the samples.
