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.

    POLLINATOR FAUNA, DIVERSITY AND THEIR ROLE IN ENHANCING YIELD IN CHILLI, Capsicum annuum L.
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 21-08-08) CHAITRA, T.; KUBERAPPA, G. C.
    Studies on pollinator fauna, diversity and their role in enhancing yield in chilli was carried out during 2018-19 at the University of Agricultural Sciences, GKVK, Bengaluru. Anthesis was between 06:00h and 07:00h and pollen dehiscence was between 07:00h and 10:00h. Thirteen species of insect pollinators were recorded on chilli, of which ten species belonged to order Hymenoptera, one to Lepidoptera and two to Diptera. Among the pollinators, honey bees constituted 64.01 per cent. The peak foraging activity was observed between 09:00 AM to 11:00 AM of the day. Average fruit set (100.00 %), mean of single fruit weight (7.65g and 7.40g), mean fruit girth (1.18cm and 1.65cm), mean fruit length (8.95cm and 6.50cm), seeds capsule-1 (48.70 and 61.03) and mean seed weight (5.25g and 6.05g) were higher in eight visits flower-1 in case of Apis dorsata and Tetragonula iridipennis, respectively. The results of modes of pollination on quantitative parameters such as average fruit set, mean fruit weight, mean fruit girth, mean fruit length, seeds capsule-1 and mean seed weight and qualitative parameters such as moisture per cent, total soluble sugars, germination per cent and seedling vigour index were higher in open pollination.
