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.

    PRUNING PRACTICES FOR MAXIMIZATION OF MULBERRY LEAF PRODUCTIVITY UNDER UAS SERI SUVARNA TECHNOLOGY AND REARING PERFORMANCE IN RAINFED CONDITION
    (University of Agricultural Sciences GKVK, Banglore, 2007-09-17) R. LAKSHMINARASIMAPPA; Dr. K.P. CHINNASWAMY
    Field experiment was carried out to investigate the effect of pruning practices for maximization of mulberry leaf productivity under UAS Seri Suvama technology on growth and yield of Ms mulberry variety and the silkworm B. mori L. in relation to rearing performance in rainfed condition at Department of Sericulture, UAS, GKVK, Bangalore during the year 2004-05. The results indicated that mulberry growth parameter viz., number of branches and leaves, leaf yield, leaf moisture, chlorophyll a, b content, total chlorophyll content, total soluble sugar and protein content NPK, Ca, Mg and S content were influenced by the pruning practices. However, pruned crop shows 90 cm height more / higher of all the above parameters which is followed by pruning at 60 cm, 30 cm bottom pruning, 90, 60 and 30 cm with normal shoots as compared to non-UAS Seri Suvarna. Similarly, the soil moisture content at 60 cm depth and soil arthropods populations like beetles, grubs, termites, centipedes and earthworm were higher in treatment of 90 cm height pruned plots as compared to other treatment. The larval weight cocoon weight, growth rate, shell weight, shell percentage, silk productivity and ERR percentage and silk filament was also higher in 90 cm height, pruned plots, which is followed by 60, 30 cm bottom pruning 90, 60, 30 cm height with normal shoots compared to non-UAS Seri- Suvama. The instar duration larval duration, silk denier and disease incidence was less in 90 cm height pruned plot as compared to other treatment. Similarly, benefit cost ratio 90 cm height pruned crop was 5 : 73 which is followed by 5:11 and 5 : 07 in 60 and 30 cm height pruned plot respectively, the lowest B:C ratio of 1 : 92 was obtained in non-UAS Seri Suvarna technology
