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 FARMERS PRACTICES OF SILKWORM (Bombyx mori L.) REARING AND IN VIVO BACILLUS INFECTION IN ZONE – 5 (KOLAR AND CHIKKABALLAPUR DISTRICTS)
    (University of Agricultural Sciences GKVK, Bangalore, 2013-08-24) ANUSHA, H G; BHASKAR, R N
    The Studies on farmers practices on silkworm (Bombyx mori L.) and in vivo Bacillus infection in zone –5 (Kolar and Chikkaballapur districts) was carried out during 2011-2013 in the Department of Sericulture, University of Agricultural Sciences, GKVK, Bangalore -65. The survey data collected during June to May 2011 to 12 revealed significant differences on type of rearing house, Number of tiers, Space between the tiers, airouts and ventilators. In general the application of FYM to acre of mulberry garden was ranged from 3-5 tonnes/acre with cocoon yield of 55-96 kg/100 dfls. The quantum of urea, complex and DAP+Complex applied in their garden was ranged from 0-150 kg/acre. These results showed that, the farmers of these areas are not applying sufficient quantity of manures and fertilizers to produce quality leaf. Among houses surveyed, stone house, RCC building and Brick house have different number of tiers which were ranging from 4-6 and the space between the tier was 1-2.5 ft recorded cocoon yield of 53-72 kg/100 dfls. On contrary, RCC building of 50×35-60×45 ft and Brick house without airouts not influenced on cocoon yield as it is reflected in the data. The summer season was noticed maximum of 20 per cent diseases incidence compared to rainy and winter season. In addition, to prevent the diseases, all the farmers were using 3-4 kg of bed disinfectants in their rearing. Out of which, Ankush found to be universally accepted bed disinfectant. The in vivo effect of Bacillus infection in third, fourth and fifth instar larvae of PM and CSR2 breeds revealed significant variation in all rearing parameters. Out of which, Bacillus (midgut) inoculums administered to fifth instar larvae was recorded 44.30 per cent mortality which was comparatively higher than remaining two instars experimented. Therefore, it is inferred that, CSR2 breed showed high sensitivity to Bacillus infection than Pure Mysore.
