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.

    STUDIES ON HERBIGATION IN AEROBIC RICE [Oryza sativa L.]
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2016-12-27) ABHISHEK, G.M; Thimmegowda, M.N.
    A field experiment was conducted during summer 2015 at ZARS, UAS, GKVK, Bengaluru involving twelve treatments laid out in RCBD design with three replications in drip irrigated aerobic rice using KRH-4 hybrid. The treatments comprised pre and post emergent herbigation, hand weeding, intercultivation, their combinations, weedy check and weed free check. Among herbigation treatments, pre-emergent herbigation of pretilachlor + bensulfuron methyl 6.6 % GR @ 10 kg ha-1 + one hand weeding + one intercultivation (T10) recorded higher grain (8954 kg ha-1) and straw yield (11371 kg ha-1), it was on par with weed free check (9460 and 12235 kg ha-1, respectively). Similar trends were also observed in growth and yield attributes. Weedy check recorded significantly lower grain and straw yield (1379 and 1676 kg ha-1, respectively). Significantly lower total weed population, dry weight and weed index was recorded in weed free check (0.0 0.25 m-2, 0.0 kg ha-1 and 0.0 %, respectively) followed by T10 (18.67 0.25 m-2, 1716 kg ha-1 and 5.25 %, respectively) whereas it was significantly higher in weedy check (70.67 0.25 m-2, 10790 kg ha-1 and 85.46 %, respectively). Higher weed control efficiency and net returns was achieved in weed free check (100 % and Rs. 103525 ha-1, respectively) followed by T10 (84.09 % and Rs. 98865 ha-1, respectively) indicating the superiority of weed free condition and pre and post emergent herbigation coupled with one intercultivation for weed management in aerobic rice. Considering the labour drudgery, herbigation forms the efficient weed management strategy for drip irrigated aerobic situations.
