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.

    EFFECT OF ORGANIC MULCHES AND GREEN MANURING ON SOIL MOISTURE CONSERVATION, INFILTRATION GROWTH AND YIELD OF MAIZE (Zea mays L.) IN ALFISOLS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2018-07-30) MAJEED PASHA, MD; RAJASHEKARAPPA, K.S.
    A field experiment was conducted at the Department of Agricultural Engineering, UAS, GKVK, Bengaluru during kharif 2017, to study the “Effect of organic mulches and green manuring on soil moisture conservation, infiltration, growth and yield of maize (Zea mays L.) in Alfisols”. The experiment was laid out in RCBD comprising nine treatments replicated thrice. Growing sunhemp in between maize rows as intercrop and incorporating as insitu green manuring resulted in better soil moisture content at 60, 75, 90 DAS and at harvest at 0 -15 and 15- 30 cm depth. The soil temperature at 5 and 10 cm depth recorded lower in the same treatment. After harvest, the higher infiltration rate (5.80 cm hr-1) lower bulk density (1.42 g cc-1), higher water holding capacity (47.51%), pH (6.42), higher soil organic carbon (0.46%), available nitrogen, phosphorous and potassium (227, 28.67 and 133.78 kg ha-1) was recorded. Also growing sunhemp in between maize rows as intercrop and incorporating as insitu green manuring resulted in better plant growth, yield and yield components. The highest gross returns (Rs.77991) net returns (Rs. 51088) and B:C ratio (2.90) was noticed under sunhemp insitu green manuring. From this investigation, it can be inferred that introduction of one row of sunhemp in between maize rows and incorporating at 30 DAS found superior with respect to yield and economic returns besides improving soil fertility and productivity.
