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.

    EVALUATION AND CHARACTERIZATION OF BIO FERTILIZER AND BIOLOGICAL CONTROL ACTIVITIES OF AERATED AND NON- AERATED COMPOST TEA AGAINST LATE BLIGHT IN POTATO AND BLAST DISEASE IN RICE CROPS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-16) ROOPASHREE, K. M.; Veena, Anil S
    Devastating crop diseases such as Late Blight of Potato and Blast of Rice cause extensive loss of yield globally. The environmental pollution caused by excessive use of agrochemicals, has led to use of biological alternatives such as ‘Compost tea’, an enriched microbial liquid suspension. Earlier work by Anil and Coworkers showed that, aerated Compost Tea (ACT) in an integrated formulation with reduced fungicide (RF) increased plant biomass, chlorophyll, yield and managed Late Blight in Potato field experiments, (Anil et al., 2017). The objective of the present study was to comparatively evaluate the effects of aerated and non-aerated compost tea (ACT & NCT), along with the reduced number of sprays (ACT5, and NCT5) on Potato and Rice crop. All aerated and non aerated compost tea treatments with ten and five sprays resulted in higher biomass, increased chlorophyll, yield. ACT10 sprays among all treatments managed Late Blight of Potato and Blast of Rice to the best extent. However, lower number of sprays and nonaerated formulations also managed the disease. Biochemical analysis indicates induced systemic resistance by induction of defense as evaluated by increased SOD, POX, Phenolic and flavonoid levels. An evaluation of microbial composition showed compost teas have a rich microbiota. The fungal and bacterial isolates from compost tea showed significant inhibition of P. infestans and M. grisae on dual plate inhibition assays. The results of this study indicate that Compost tea based strategy is an eco friendly, effective biocontrol and biofertilizer in managing Late Blight of Potato and Blast of Rice.
