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.

    BIORESPONSES OF MULBERRY (Morus spp.) AND SILKWORM (Bombyx mori L.) TO SILKWORM PUPAL PROTEIN AND COMPOST
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-09-28) MAHESH, D. S.; Narayanaswamy, T. K
    An experiment was conducted during 2015-17 by application of 50% N through SPB + 50% N + recommended dose of P & K/ha/year through chemical fertilizers (T6) recorded highest major nutrients content (available N, P2O5 and K2O of 286.50, 50.18 and 186.32 kg/ha) in soil, highest mulberry growth (plant height of 163.72cm), leaf yield (1005.37g/plant) and quality parameters like leaf moisture (74.26 %), total chlorophyll (2.45mg/g), crude protein (20.16%), total soluble protein (12.02%) and total soluble sugar (13.12%). Further, significantly higher silkworm rearing parameters such as, mature larval weight (38.63g/10), less fifth instar larval duration (156.10 hours), total sugar (2.47 %), lipid (2.98 %), highest ERR (98.80%), lower disease incidence (1.20%) and cocoon parameters like maximum single cocoon weight (1.88g), shell weight (0.30g), shell ratio (15.95%), cocoon filament length (915.70m), least denier (2.29), fibroin (20.85μg/ml) and sericin (11.86μg/ml) content were recorded when silkworm fed with mulberry leaves of T6 treatment. Significantly higher mulberry growth (plant height of 158.81 cm), leaf yield (1047.92 g/plant) and quality parameters like higher leaf moisture (74.33), total chlorophyll (2.58 mg/g), total sugars (13.22 percent), total soluble protein (12.18 percent) and crude protein (21.14 percent) were recorded in V1 variety sprayed with SPP @ 2 percent + RDF + 20 MT FYM/ha/year (T6) at 60th day after pruning. Further, significantly higher silkworm rearing parameters like mature larval weight (38.78g/10), fifth instar larval weight (38.78g/10), less fifth instar larval duration (156.58 hours) , total sugar (2.52 %), lipid (3.04 %), lesser disease incidence (0.89 %), higher effective rate of rearing (99.10 %) and cocoon parameters like maximum single cocoon weight (1.92 g), shell weight (0.31 g), shell ratio (16.14 %), cocoon filament length (922.14 m), lowest denier (2.27), fibroin (21.09 μg/ml)and sericin (12.02 μg/ml) respectively were recorded when silkworm fed with mulberry leaves of T6 treatment.
