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.

    Nitrogen release, sediment outflow and water quality parameters with uncoated and neem coated urea application from selected land slopes under simulated rainfall conditions

    The nutrients loss from fertilized agricultural lands not only results in the reduction of fertility of soil but also the accumulation of these chemicals in various water bodies produce harmful toxic effects rendering it unfit for human as well as for animal consumption. Urea fertilizer is highly soluble in water and volatile in nature and constitutes about 82% of the nitrogenous fertilizer used in India. The various pathways of nitrogen loss are volatilization, leaching, de-nitrification and through runoff. To minimize the nitrogen losses and environmental hazards, it becomes imperative to improve the efficiency of nitrogen use by controlling nitrogen release rate of urea as per the plants’ need. To accomplish this task, slowrelease fertilizers (SRF) are produced by coating urea with neem and other biodegradable materials. This neem coated urea helps in retaining nutrients for a longer time and ensures nitrogen availability to plants for significantly longer periods than an uncoated urea fertilizer. In this study extensive experimentation was done in the open field on experimental plots using uncoated and neem coated urea to study their nitrogen release pattern and its effects on sediment outflow and water quality parameters under varying rainfall intensity and different land slope conditions. To create controlled conditions of rainfall, artificial rainfall was generated by developing a portable rainfall simulation system which was capable of producing rainfall almost similar to natural rainfall with complete manual control. As per mandate of this study, apart from control (No crop i.e., bare soil), the nitrogen release rate, sediment outflow and water quality parameters were observed from (i) maize crop land and (ii) marigold crop land. Soil samples and runoff samples were collected and analysed to determine the status of nitrogen content in the soil and runoff water quality parameters such as TDS, pH and electrical conductivity on 2nd day, 6th day, 10th day and 14th after coated and uncoated urea applications. It was observed that developed portable rainfall simulator generated rainfall very similar to natural rainfall. The soil nitrogen content both in case of ordinary urea as well as neem coated urea applications was high in the beginning and decreased with time till 14th day. In case of ordinary urea, the rate of decrease in soil nitrogen content was very fast in the beginning (during 2nd day to 6th day) while in case of neem coated urea, the nitrogen release rate was slow and steady throughout the period. It thus implied that in case of neem coated urea application, the nitrogen becomes available to soil at a uniform rate for longer duration in bare land as well in crop land conditions. The percent nitrogen release up to 14th day after application of uncoated and neem coated urea with maize crop conditions was recorded to be 32.06% and 24.20% at 0% land slope, 33.11% and 25.23% at 2% land slope, 34.22% and 27.43% at 4% land slope, 37.68% and 30.60% at 8% land slope and 39.54% and 31.16% at 12% land slope, respectively under similar conditions. Similarly, sediment out flow and runoff water quality parameters were observed and analysed to see the effect of coated and uncoated urea applications under various combinations of input variables. To quantify the effect of involved variables on nitrogen release and water quality parameters, mathematical relationships were also developed for various combinations of the input variables.

    Sediment outflow from mulch treatments at varying land slopes under simulated rainfall conditions
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-07) Singh, Sachin Kumar; Kashyap, P.S.
    The problem of soil erosion in India is very serious. About 18.5% of the world’s total soil erosion takes place in India, which is about16.4tons/ha/year.Organic mulches are very effective in preventing soil erosion,reduce sediment transport rate, runoff rate and increasing infiltration. The study was carried out with the objectives to observe the sediment outflow from various mulch treatments at selected land slopes under simulated rainfall conditions by using rainfall simulator of size 10 m × 1.2 m × 0.5 m with the locally available soil material collected from College of Agriculture Business Management, Pantnagar. In the present study, paddy straw, hay and trash mulches were selected to observe the effect of mulching in soil loss reduction. The quantity of these three types of mulches were taken as, 6 ton/ha, 8 ton/ha and 10 ton/ha and for each mulch treatment, three rainfall intensities viz. 11cm/h, 13cm/h and 14.65cm/h at 0%, 2% and 4% land slopes were selected. The duration of rainfall was fixed (10 minutes) for every mulch treatment. The total runoff volume was found to be varying with different mulch rates for particular rainfall input and land slope. The runoff distribution pattern was observed to be increasing with the increase in land slope. The average sediment concentration and outflow was found to be increasing with the increasein land slope,but sediment concentration and outflow decreased with increasing mulch rate for particular land slope and rainfall intensity. The sediment outflow rate for no mulch treated land was higher as compared to trash mulch, hay mulch and paddy straw mulch treated lands. Mathematical relationships were developed for relating sediment outflow rate, sediment concentration,land slope and rainfall intensity for a particular mulch treatment. It was observed that values of sediment outflow rate and average sediment concentration had a good correlation with rainfall intensity and land slope for each mulch treatment. The correlation coefficients of developed models were found to be more than 90%.
