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.

    Impact of urea embedded nano silica in rice–wheat cropping system on normal alluvial and acidic hill soils
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-05) Singh, Kharag; Shri Ram
    Laboratory and pot culture studies were conducted for evaluation of mesoporous nano silica (mNS) loaded with urea in Rice–Wheat cropping system on normal alluvial and acidic hill soils. This pot culture trial includes nine treatments consisted T1-control, ,T2-N30P60K40, T3-N60P60K40, T4- N90P60K40, T5-N120P60K40, T6-N30(mNS)P60K40, T7-N60(mNS)P60K40, T8-N90(mNS)P60K40 and T9-N120(mNS)P60K40 in completely randomized block design (CRD) with three replications. Laboratory study synthesis and characterization of mNS was conducted in Bio-Nanotechnology unit, and pot culture experiment in poly house of college of Agriculture, G.B Pant University of Agriculture and Technology, Pantnagar. In this study, magnetized distilled water (MDW) with various physicochemical characteristics have been used to enhance the urea loading efficiency into mNS as compared to distilled water (DW). The mNS was characterized by Fourier Transform Infrared Spectroscopy (FTIR), Energy-dispersive X-ray (EDX), and Field Emission Scanning Electron Microscope (FESEM). We compared the effects on seed germination of wheat with magnetized and normal distilled water, by using as treatments viz. mNS, urea embedded mNS, and ordinary urea under laboratory conditions. Comparing to mNS in DW, remarkable increase in root (4-fold) and shoot (1.85-fold) lengths were observed with mNS in MDW. The root and shoot length in case of urea embedded mNS in MDW were 2.05 and 1.77 times greater than mNS with distilled water, respectively. The seed germination and root and shoot length increased significantly with the exposure to 0.5% (w/v) mNS in magnetized water (mNS-MDW) and urea embedded mNS in magnetized water (mNSU-MDW) in comparison to normal distilled water (DW). In pot trial studies with crops, growth parameters, yield contributing characteristics, yields and nutrients uptake by rice and wheat were significantly higher with nitrogen application through urea embedded nano silica in comparison to N application through ordinary urea in normal alluvial and acidic hill soils. On the contrary, nitrogen application @ 120 kg ha-1through urea embedded nano silica showed poor performance as compared to lower doses of nitrogen @ 90 and 60 kg ha-1 through urea embedded nano silica in acidic soil. But lower doses of nitrogen @ 90 and 60 kg ha-1 through urea embedded nano silica resulted significantly higher growth parameter, yield attributes, yields and nutrients uptake by wheat crop as compared to same doses of nitrogen through ordinary urea in acidic soils. All treatments of urea embedded nano silica, showed significant increase available N, P and K in soils after rice and wheat harvest under both soil conditions. Slight decrease soil pH in normal alluvial soil and slightly increase in acidic hill soil was recorded after both crops harvest. The results indicated sustained release of nutrients from the urea embedded nano silica, which are preliminary indication but it opens the doors to use nanomaterials as an efficient nanofertilizer.
