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 PLANT DEFENCE INDUCERS FOR MANAGEMENT OF LEAF BLIGHT OF SUNFLOWER
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2019-09-05) DATHATREYA; KARUNA, K.
    Sunflower crop suffers from many diseases of which Alternaria blight has been considered as a potentially destructive disease. In vitro evaluation of plant defense inducers revealed that maximum inhibition of A. helianthi was recorded in salicylic acid at 200 ppm (43.79%) followed by monopotassium phosphate at 200 ppm (40.34%). In field conditions, seed treatment followed by foliar spray of salicylic acid at 100 ppm at 30 and 45 DAS increased the growth parameters like plant height (215.46cm), stem girth (3.54 cm), number of leaves (38.43) and chlorophyll content (48.53). Seed treatment followed by foliar spray of salicylic acid at 100 ppm showed least disease severity (23.33%) at 50 percent flowering with higher yield (2421 Kg ha-1) which was on par with seed treatment followed by foliar spray of salicylic acid at 50 ppm with disease severity of (23.33%) at 50 per cent flowering and seed yield of 2397 Kg ha-1.The defense enzymes superoxide dismutase (40.45 μg/50 per cent inhibition) and peroxidase (16.86 μg/ min/ mg protein) and secondary metabolites such as phenols (73.53 mg/g FW) and flavonoids (68.71mg/g FW) increased in seed treatment followed by foliar spray of salicylic acid at 100 ppm which resulted in least disease severity.
