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.

    STUDIES ON BIO-PRIMING OF PADDY SEEDS TO COMBAT BLAST DISEASE (Magnaporthe oryzae L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2016-08-20) AMRUTA, N; Narayanaswamy, S
    A study was conducted in the laboratory, greenhouse and field to know the influence of bio-priming on paddy seeds against blast disease at GKVK, Bengaluru and VC, Farm Mandya. The total 60 bacterial strains were isolated from paddy rhizosphere and used for in vitro and in vivo evaluation against M. oryzae along with two reference strains B. subtilis and P. fluorescens and eleven bacterial strains showed maximum inhibition. Thirteen strains were characterized as bacteria belong to genera Bacillus, pseudomonas, Serratia, Alcaligenes and Proteus using 16S rRNA sequencing. The bacterial isolates exhibited antagonist property showed the presence of antimicrobial peptide genes. In vitro evaluation revealed that the B. amyloliquefaciens UASBR9 and Serratia marcescens UASBR4 found most effective against the pathogen (84.14 and 76.83 per cent respectively) compared to reference cultures RBs-1 (72.00 %) and RPf-1 (55.24 %). The least PDI and highest germination was recorded in HR-12 seeds bioprimed with UASBR9 (0.69 and 99.00 %) compared to untreated control (3.43 and 95.00 %) under in vivo condition. Seeds bio-primed with formulated product of UASBR9 and talc+MgSO4 @10g/kg seed was recorded least PDI (6.63 %), highest seed yield/plot (0.68 kg) and maximum germination (99.50 %) compared to untreated control (20.25 %, 0.27 kg and 90.00 %, respectively). Seed bio-primed with UASBR9 showed induced systemic resistance in rice on challenge inoculation with M. oryzae and increased activities of peroxidase (0.563 min-1 gram-1), PPO (0.825 min-1 gram-1) and PAL (6.849 nmol t-CA) and defense-related enzymes response against pathogen compared to untreated control.
