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.

    UTILIZATION OF SILKWORM (Bombyx mori L.) PUPAL RESIDUE FOR BIOCONTROL AND VALUE ADDITION
    (University of Agricultural Sciences, Bengaluru, 2018-08-30) VISHAKA, G. V.; Narayanaswamy, T. K.
    The present study was undertaken to utilize silkworm pupae disposed by silk reeling units viz., Vijayapura, Sidlaghatta and Chintamani of Chikkaballapur district of Karnataka. Designed special equipment for extraction of silkworm pupal residue biosoft descent (SPRBD) from silkworm pupal residue collected from reeling units. Significantly higher quantity of 3.10 Kg (52 %) SPRBD was extracted at 18 tonnes pressure. Invitro evaluation of SPRBD exhibited that at 40 %, significantly highest inhibition of 100 % mycelial growth was documented for Alternaria solani followed by 90.00 % (Fusarium oxysporium). Evaluation of SPRBD against Alternaria solani under glass house conditions proved minimum disease severity at 45, 60, 75 and 90 days (6.70, 14.33, 28.93 and 43.10 %) in the tomato plants treated with SPRBD @ 10 % before and after incidence of disease (T6: SPRBD @ 10% spray before and after inoculation with Alternaria solani). The SPRBD as nutrient source on tomato yielded highest plant height (96.20 cm), number of branches per plant (28.67), number of flowers per plant (87.67), stem girth (2.17cm) recorded on 90 days after planting, respectively in T4 (SPRBD @ 4 % + T8- Recommended dose of fertilizer + FYM/ha/year). Significantly highest Shoot weight (173.10 g), root weight (10.17 g) and total biomass per plant (37.23 g) was yielded at harvest stage. The yield parameters like total number of fruits (50.17), fruit weight (50.50 g) and fruit yield per plant (4.27 kg) was exhibited highest in T4 (SPRBD @ 4 % + T8). The silkworm pupal Dark Chocolate (SPDC), silkworm Pupal White Chocolate (SPWC) and silkworm pupal tamarind ball (SPTB) with 5 per cent SPRP incorporated and for masala cookies 7 per cent was found to be best accepted with scores for appearance (8.0, 7.4,7.5 and 7.8), colour (8.1, 7.6, 7.6 and 7.6), texture (8.1, 7.4, 7.8 and8.0), aroma (8.0,7.4 ,7.8 and 7.4), taste (8.2,7.5 ,7.0 and7.6) and overall acceptability (8.2,7.4,7.7 and7.6).

    STUDIES ON FEASIBILITY OF INTERCROPPING OF SOLANACIOUS VEGETABLES IN MULBERRY
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-10) VISHAKA, G. V.; Ramakrishna, Naika
    A field experiment was conducted during August to November 2014 to study the effect of intercropping of solanacious vegetables in Y-1 mulberry garden at farmer's field in Bhaktharahalli village, Chikkaballapur district. The experiment consisted of seven treatment combinations laid out in a randomized block design with three replications. The results revealed that significantly higher available soil nitrogen (226.02 kg ha-1), phosphorous (36.20 kg ha-1) and potassium (176.20 kg ha-1) was recorded in sole mulberry plot. Further, the plant height ( 159.43 cm), number of branches per plant (13.31 ), number of leaves per shoot (20.62), number of leaves per plant (121.81), leaf area (377.38 dm2), leaf area index (13.81) and leaf yield (5.81 t ha-1 crop- 1) were also significantly high in sole mulberry. Performance of silkworm (PM x CSR2) fed on the leaves harvested from mulberry + solonacious vegetable intercropping system did not show significant difference with respect to larval weight, total larval duration, ERR, cocoon weight, shell weight, shell ratio, pupal weight, single cocoon filament length and denier. However, significant difference was recorded only for the cocoon yield (659 g DFL-1) and number of defective cocoons ( 11.00) in the sole mulberry treatment. Further, the incidence of flacherie, grasserie and muscardine in all instar worms was numerically low in all the treatments. A significant effect in suppression of weeds was noticed in mulberry + chilli intercropping system (9.67 weeds plor1 ). Higher net return (􀀊 5, 81,996/- ha-1 crop-1) was obtained from mulberry+ tomato intercropping and higher cost benefit ratio (3 .61) was obtained
