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.

    EFFECT OF PACKAGING MATERIALS AND ZEOLITE ON SEED LONGEVITY OF ONION SEEDS (Allium cepa L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-01) AKSHATHA., K. S; NARAYANASWAMY, S.
    A laboratory experiment was conducted to study the effect of packaging materials and zeolite on seed longevity of onion seeds (Allium cepa L.) at Department of Seed Science and Technology, UAS, GKVK, Bengaluru during 2016-17. The study comprised of four packaging materials viz., cloth bag, aluminium foil, vacuum polythene bag and super grain bag and two types of zeolite viz., zeolite powder and zeolite beads stored for 10 months with FCRD in three replications. The results revealed that among the packaging materials, the seeds stored in aluminium foil recorded highest seed quality attributes viz., germination (70.49 %), seedling length (11.21 cm), seedling dry weight (1.91 mg), seedling vigour index I (792), speed of germination (0.806), dehydrogenase activity (1.124 A480nm), amylase activity (72.4 μg/g), moisture content (8.52 %), electrical conductivity (727 μS/ppm) and total soluble sugars (125.63 μg/ml) at the end of ten months of storage. Among the zeolite types, seeds dried to 5 per cent moisture content using zeolite beads resulted in higher seed quality parameters viz., germination (68.97 %), seedling length (10.64 cm), mean seedling dry weight (1.88 mg), seedling vigour index I (739), speed of germination (0.806), dehydrogenase activity (1.115 A480nm), amylase activity (74.8 μg/g), moisture content (8.90 %), electrical conductivity (743 μS/ppm), and total soluble sugars (124.45 μg/ml) was observed at the end of ten months of storage. The study can be concluded that the onion seeds dried to 5 per cent moisture content using zeolite beads and stored in aluminium foil could be stored for ten months satisfactorily.
