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.

    IDENTIFICATION OF SUITABLE CASTOR GENOTYPES FOR DUAL PURPOSE OF ERICULTURE AND SEED PRODUCTION
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK ,BANGALORE, 2007-09-19) CHANDRASHEKHAR, S; GOVINDAN, R
    Castor genotypes raised under rainfed condition exhibited significant variation with respect to leaf and seed yield with higher being in DCS-85, Similarly, foliar constituents viz., moisture, crude protein, total carbohydrates, nitrogen, phosphorus, potassium, calcium and sulphur were more with DCS-85; chlorophyll 'a', 'b' and total chlorophyll contents with 48-1; while magnesium with'|3CH-177. Eri silkworms fed on leaves of selected castor genotypes exhibited marked differences with respect to bio-energetics both on fresh and dry weight basis with better performance being in DCS-85. Further, DCS-85 registered superior ERR, cocoon weight, cocoon yield, shell weight, shell yield, shell ratio, silk productivity, fibroin and sericin. However, eri pupae formed by the worms nourished with leaves of DCS-9 recorded higher pupal weight and fecundity, while egg hatching was more with DCS-9, DCS-85 and Local genotypes. In larval, cocoon and grainage indices, larval weight, cocoon weight, silk, eclosion and oviposition indices, leaf - cocoon ratio, leaf - cocoon conversion rate, growth index (% pupation) and net reproductive rate were superior with DCS-85; pupal weight index with DCS-9; larval, pupal, and larval - pupal duration indices with Kranti, DCH-177, DCS-85 and Local; hatching index with DCS-9, DCS-85 and Local; while leaf egg ratio was better with GCH-4. The fbllar consliLuenb of castor genotypes v/j., bio-chemical, major and secondary nutrient status of leaves had marginal influence on bio-energetic, economic and growth indices showing positive trend with respect to improvement in the performance of the eri silkworm. From the economic point of view, castor genotype DCS-85 can be raised under i rainfed condition for seed production and ericulture (@ 50% defoliation) to realize more B:C ratio. Hence, DCS-85 genotype could be used with cost effectiveness for dual purpose of castor seed and eri cocoon production under rainfed situation
