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.

    Role of Integrated Nutrient Management in Mulberry And Its Impact on Seed And Commercial Cocoon Production
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2007-12-08) AMARNATHA, N; NARAYANASWAMY, T.K
    The role of integrated nutrient management in mulberry and its impact on seed and commercial cocoon production was studied under field condition at MRS, Hebbal, Bangalore during 2005-07. The larvae of PM and CSR2 fed on mulberry leaves raised through the application of biofertilizer @ 10 kg/ha each of Azospirilium brasilense + Aspergillus awamori + 20% recommended nitrogen each through compost, vermicompost, green manure, castor oil cake and 20% N with recommended dose of P and K through inorganic fertilizers (T4) exhibited significantly higher grownup larval weight, effective rate of rearing (96.81 and 96.38%), cocoon yield (43.59 and 70.29 kg/100 DFLs), cocoon weight, shell weight, silk productivity (2.483 and 5.953cg/day), cocoon filament length, pupal weight, rate of pupation, rate of moth emergence (92.13 and 88.50%), male and female moth weight, fresh weight of ovaries, fecundity (466.24 and 496.40 eggs/laying) and hatchability (95.31 and 94.93%) with significantly minimum disease incidence, chawki duration, fifth instar larval duration, total moulting duration, total larval duration (651.79 and 615.75h), pupal duration and cocoon melting rate. The grownup larval weight (3.678g), larval volume, ERR (92.17%), cocoon yield (67.10 kg/100 DFLs), cocoon weight, pupal weight, shell weight, shell ratio (24.41%), silk productivity and cocoon filament length (865.57m) of PMxCSR2 were maximum when its parents were fed on mulberry leaves raised on T4 treatment. While the chawki duration (254.12h), fifth instar larval duration (192.23h), total moulting duration (101.71h), total larval duration (672.28h) and disease incidence (5.83%) of PMxCSR2 were significantly minimum when its parents were reared on mulberry leaves obtained by the application T4 treatment. Thus, PMxCSR2 hybrid performed better with respect to larval, cocoon and post cocoon traits, when their parents were provided with mulberry leaves obtained by the application of microbial inoculants, organics and inorganic fertilizers as an integrated nutrient approachy
