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.

    Pollinators diversity with special reference to role of honey bees in quantitative and qualitative improvement of cucumber, Cucumis sativus L. var Hassan Local was carried out during 2010 at vegetable seed production plot, Division of Horticulture, University of Agricultural sciences, GKVK, Bangalore. At flowering stage, cucumber was visited by twenty eight species of insects, of which twenty species belonged to Hymenoptera, two to Diptera, four to Lepidoptera and two to Coleoptera. Of the total pollinators visited cucumber, honey bees constituted 84.88 per cent, whereas other pollinators constituted 15.11 per cent. The peak pollen and nectar foraging activity was observed between 1100 to 1300 h. The quantity of nectar and total soluble sugar was gradually increased with the advancement of the time and reached maximum at 1500 h in both male and female flowers. The percent flower drop, fruit set, fruit weight, fruit volume, fruit length, number of seeds/ fruit and seed weight were maximum in ten bee visits per flower. Impact of honey bees pollination on quantitative and qualitative parameters in cucumber such as per cent flower drop, fruit set, fruit weight, fruit volume, fruit length, number of seeds/fruit, seed weight, moisture content, ash content, germination percentage and seedling vigour index were maximum in open pollination plots, followed by plots caged with A.cerana, A.florea and T.iridipennis.
