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.

    INVESTIGATION ON DOLICHOS MOSAIC VIRUS DISEASE ON FIELD BEAN
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-16) ANANDA BHEEMASHANKAR, AVARAD; Ramappa, H. K.
    Dolichos mosaic virus disease on field bean is caused by a potyvirus is characterised by the symptoms like vein clearing, uneven leaf lamina, twisting of leaves, mosaic mottling and blistering on newly formed trifoliate leaves. The incidence of the disease in the Southern Karnataka ranged from 16.01 per cent to 26.98 per cent. The highest disease incidence was recorded in Ramanagara (26.98 per cent) and lowest disease incidence in Kolar (16.01 per cent) during 2016. Five hundred and forty five genotypes screened under field condition against dolichos mosaic virus disease. Among 545 genotypes, 41 genotypes showed resistant reaction, 377 genotypes (HA-3 and Kadale avare) were showed moderately resistant reaction with the range of 6.98 to 14.49 per cent disease incidence and 100 genotypes involving popular variety HA-4 were showed moderately susceptible reaction with disease incidence range of 16.56 to 24.22 per cent. Sixteen and eleven genotypes were showed susceptible and highly susceptible reaction respectively. Barrier crop maize + three sprays of Imidacloprid 17.8 % SL@ 0.5 ml/L at 20, 30 and 40 DAS or three sprays of Imidacloprid 17.8 % SL @ 0.5 ml/L alone at 20, 30 and 40 DAS were found effective in reducing the incidence of dolichos mosaic virus, its vector and increasing grain yield followed by three sprays of 3 % Mineral oil at 20, 30 and 40 DAS was also found effective in management of dolichos mosaic virus disease, its vector (Aphis craccivora) and increasing grain yield.
