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 OF MICRONUTRIENTS ON BIORESPONSES IN MULBERRY (Morus spp.) AND SILKWORM (Bombyx mori L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2016-10-04) SOWMYA, P; Narayanaswamy, T. K.
    The experiment on Studies of micronutrients on bioresponses in mulberry (Morus spp.) and silkworm (Bombyx mori L.) was conducted at the Department of Sericulture, UAS, GKVK, Bengaluru during 2014-2016. In this experiment eight treatments were evaluated by conducting the experiment in RCBD. Among the treatments, T5 (100 % recommended dose of N through 20 % each of compost, Glyricidia maculata, castor cake, vermicompost and urea + 10 kg each of Azospirillum brasilense + Aspergillus awamori bio- fertilizer + remaining P, K through chemical fertilizer + FYM 20 t/ha + ZnSO4 7H2O @ 20 kg/ha/year) recorded higher leaf yield (65.07 ton/ha). The leaf quality also significantly improved in this treatment recording higher total soluble protein (12.07 %), crude protein (20.24 %) and total sugar (13.08 %). In the silkworm rearing T8 (T2 + Borax @ 2 kg/ha/year) recorded higher V instar larval weight (38. 38 g/10 larvae), cocoon weight (1.92 g/cocoon), pupal weight (1.57 g/pupae) and shell weight (0.31 g/shell). The T5 treatment recorded higher shell ratio (16.33 %), ERR (98.44 %), higher fibroin (21.58 μg/ml) and sericin (12.33 μg/ml) content of cocoon, grainage parameters viz., moth emergence percentage (97.80 %), fecundity (486.67/dfl) and hatching percentage (92.42 %). The soil properties like Higher available N (287.00 kg/ha), P (44.40 kg/ha) and K (288.33 kg/ha) were recorded in T5. The B: C ratio of mulberry production was higher in T5 and T8 (1: 3.21). Similarly the highest B: C ratio of cocoon production was recorded in T3 (1:2.24).

    RESPONSE OF DIFFERENT MULBERRY CULTIVARS TO AZOTOBACTER BIO-INOCULUM UNDER RAINFED CONDITION
    (University of Agricultural Sciences GKVK, Bangalore, 41122) SOWMYA, P; GEETHA DEVI, T
    Application of nitrogen through biological means in the form of biofertilizers are the key to sustain sericultural productivity. A field experiment was carried out at the Department of Sericulture, University of Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bangalore during 2011-2012 to study the “Response of different mulberry cultivars to Azotobacter bio-inoculation under rain fed condition”. In this experiment six mulberry varieties and three treatments were evaluated by conducting the experiment in a split plot design. Among the treatments application of 50% N + 100% PK through chemical fertilizer + 50% N through Azotobacter + vermicompost (T3) have been found to be highly beneficial for rainfed mulberry cultivation. The physical and biological properties of the soil was significantly improved due to this treatment indicating lower bulk density(1.58g/cc) lower Ec (0.21 dsm-1), higher organic carbon content (0.52%) and higher population of Azotobacter (10.59 CFU/10-5/gm of soil). Growth and yield of mulberry was also significantly higher with this treatment recording 21 per cent higher yield compared to the control plot where 100 per cent nitrogen was applied through chemical fertilizer. The quality of leaf was also significantly improved in this treatment recording higher moisture percentage (83.69%), higher moisture retention capacity (91.98%), higher crude protein (19.39%). The cost of production per kg of leaf was lower in this treatment (1.50 Rs) compared to T1 (1.60 Rs/kg of leaf). Among the varieties the performance of RFS 175 and S13 was significantly superior recording higher leaf yield (30.62 and 29.24 ton/ha/year) on par with each other . Hence, the use of Azotobacter biofertilizers in six mulberry varieties proved that it can be used effectively for all the varieties under rainfed condition besides curtailing Nitrogen application by 50 percent.
