University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    EVALUATION OF DRIP IRRIGATION SYSTEM OF DIFFERENT MANUFACTURERS IN FARMERS’ FIELD OF BENGALURU RURAL DISTRICT
    (University of Agricultural Sciences, Bangalore, 2018-08-01) AJAY KUMAR, H.P.; Ashoka, H.G.
    The study was undertaken in Bengaluru rural district to evaluate and to assess the performance of the different companies drip irrigation systems in farmers’ fields. The farmers’ information was collected from Department of Horticulture. There are 15 farmers’ fields were selected for 5 different companies with 3 fields for each companies. The results of design evaluation showed that, 9 fields having good operating system and the 6 fields are not capable to operate the system, which results in poor performance of the system. The hydraulic parameters such as coefficient of manufacturer variation, emission uniformity, uniformity coefficient, application efficiency and distribution efficiency are found excellent at both 0.75 and 1.00 kg/cm2 operating pressure for all the irrigation companies, but the emitter flow variation is acceptable only for Jain and Sujay irrigation system at 1.00 kg/cm2 operating pressure. However not acceptable at 0.75 kg/cm2 for all the irrigation companies. The pressure variation between the inlet and outlet is not acceptable at 0.75 kg/cm2 and acceptable at 1.00 kg/cm2 for all the five irrigation companies. The value of emitter exponent and discharge coefficient varied between 0.37 to 0.79 and 2.72 to 3.34 respectively. This indicates that flow is almost turbulent. Hence all company drippers were found to be in the range of non-pressure compensating. The Jain irrigation company having better hydraulic efficiency followed by Sujay, Godavary, Megha and Vedantha irrigation Company. The cost of installation per acre for all the systems was found to be in the range of Rs. 44000/- to 50000/-.
