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.

    IN VITRO AND IN VIVO EVALUATION OF SILICON IN THE MANAGEMENT OF ROOT-KNOT NEMATODE, Meloidogyne incognita (KOFOID & WHITE), CHITWOOD, ON TOMATO
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-03) GREESHMA JEEVARAJ, GOSEKAR; Ravichandra, N. G.
    Root-knot nematode (Meloidogyne incognita) is a serious threat to tomato cultivation. Two silicon sources viz., Diatomite and Rice hull biochar were tested for their efficacy at different doses and two methods of application on egg hatching and juvenile mortality of M. incognita under in vitro and in vivo. Maximum egg hatching inhibition was observed in Diatomite (Filtered method) followed by Rice hull biochar (Filtered method) amounting to 90.22 & 89.57 per cent at 1.0 per cent concentration exposed for 120 hours. Diatomite (Filtered method) and Rice hull biochar (Filtered method) recorded 100 & 91.84 per cent mortality of J2 of at 72 hours after treatment. Minimum number of galls per root system, number of egg masses per root system and number of eggs per egg masses were recorded by Diatomite @ 2.5 g/kg of soil (63.25, 39.75 and 103.25). Maximum plant height, fresh, dry shoot, root weight and length was observed in plants treated with Diatomite @ 2.5 g/kg of soil was observed under greenhouse condition. Under field condition, Diatomite @ 12.5 g/m2 were effective against nematode with significant reduction in number of galls, egg masses per root system (66.50 and 36.75), (71.75 and 44.50) and number eggs per egg mass (98.00), (110.00). Diatomite at 12.5 g/m2 was found to increase the plant growth parameters viz., plant height, fresh, dry shoot, root length and fresh, dry root weight and yield.
