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.

    Integrated weed management in mulberry and it's effect on silkworm rearing
    (University of Agricultural Sciences, Bengaluru, 2012-09-26) K. S, Krishna; T. K, Narayanaswamy
    A study on integrated weed management in mulberry and its effect on silkworm rearing (Bombyx mori L.) was conducted at the Department of Sericulture, University of Agricultural Sciences, G.K.V.K. Bangalore during 2010-12. Common weed flora identified in experimental plots were Cyperus rotundus L. (sedges), Cynodon dactylon Pers. (grasses), Parthenium hysteroporus Commelina benghalensis Linn., Euphorbia geniculata (broad leaf weeds). Critical crop weed competition in M5 mulberry variety was carried in a RCBD with five treatments replicated four times. Among different treatments, plant height (119.4cm), number of shoots per plant (13.1), number of leaves per plant (138.8), leaf area per plant (4825.4cm2) and leaf yield (6446 kg/ha) were significantly higher in T5 (Weed free period up to 75 DAP). The effect of herbicides on growth and yield of mulberry and silkworm rearing reveled that, isoproturon 70WP 1.00 and 1.25 kg ai/ha, metribuzine 0.7 kg ai/ha, and glyphosate 41 SL 8ml/litre of water effectively controlled the weeds. However, higher plant height (97.0 cm), number of shoots per plant (13.50), number of leaves per plant (180.3), leaf area per plant (4963.4cm2) and leaf yield (25219kg/ha) was recorded in Isoproturon 70WP 1.25 kg ai/ha. Similarly, biochemical constituents like nitrogen (3.42%), phosphorus (1.45%), potassium (1.67%) total chlorophyll (2.40 mg/g), total sugars (8.67%) and crude protein (22.54%) was significantly higher in isoproturon 70WP 1.25 kg ai/ha. Economic parameters of silkworm rearing like ten mature larval weight (31.97g), cocoon weight (2.10g), shell percentage (18.67%), filament length (849.44m) and raw silk percentage (18.04%) were significantly higher in isoproturon 70WP 1.25 kg ai/ha, owing to better weed control.
