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.

    VARIABILITY AND MANAGEMENT OF Sclerotium rolfsii SACC. CAUSING FOOT ROT DISEASE IN MAJOR FIELD CROPS OF KARNATAKA.

    Sclerotium rolfsii Sacc. is a most destructive soil inhabitant, polyphagus facultative parasite. The diseases of S. rolfsii are a major constraint in production of groundnut, chickpea, finger millet, sunflower, soybean etc.. Roving survey revealed that the foot rot incidence ranged from zero to 25.33 per cent. Thirty seven pathogenic isolates obtained from different crops and regions of southern Karnataka were identified as of S. rolfsii. Six representative isolates used for cross infectivity studies revealed that the isolates BFm, BC and MFm were highly virulent (~50.00 % infection) while BelGn was moderately virulent. Finger millet and chickpea were the highly susceptible hosts (>50.0 %) whereas groundnut was moderately susceptible (46.00 %). With respect to mycelial growth, 28 isolates were found to be fast, four each were medium fast and very slow growing. The sclerotia were small, round with light to dark brown colour measuring 0.44 to 0.96 mm in diameter. In the mycelial compatibility of the selected ten isolates, 73 mycelial combinations were found to be compatible, while 27 were incompatible. ITS rDNA region amplification was at 550-600 bp in all the 12 isolates. PCR –RFLP with TaqI enzyme showed distinct fragments between the isolates thus confirming variability at molecular level. Among the different fungal antagonists tested, Trichoderma asperellum and T. harzianum-2 showed maximum mycelial inhibition in all the isolates tested. Among the fungicides tested in vitro, mancozeb and combi-products viz., cymoxanil + mancozeb, carbendazim + mancozeb, tebuconazole + trifloxystrobin and carboxin + thiram showed complete inhibition of the mycelial growth even at 500 ppm. The bio-agents viz., T asperellum and T. harzianum were significantly effective in reducing foot rot of finger millet to as low as 8.00 per cent (against 31.33 % in control) besides boosting plant growth in pot culture.
