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.

    DEVELOPMENT OF MICROBIAL CONSORTIUM FOR AGRICULTURAL CROP RESIDUE MANAGEMENT
    (University of Agricultural Sciences, Bangalore, 2023-03-30) JAGADEESH, U.; Muthuraju, R.
    A total of 173 microorganisms were isolated and qualitatively screened for lignocellulolytic activities and further screened based on quantitative and number of lignocellulolytic enzyme production like FPase, CMCase, β-glucosidase, Xylanase, Laccase, Mnp and Lip. The promising lignocellulolytic isolates viz. UASFW, UASFK2, UASBW1 and UASAP2 were selected and were identified as Phanerochaete chrysosporium UASBLCF_01, Purpureocillium lilacinum UASBLCF_02, Bacillus inaquosorum UASBLCB_03 and Streptomyces viridosporus UASBLCA_04, respectively at genomic level with compatibility study. In an in-vitro study using these isolates a consortium was developed based on their degradation potential using paddy straw, sugarcane trash and maize stover as substrates. The developed lignocellulolytic consortium showed highest degradation potential, steady decrease in Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) compared to the control. The C: N declined to 18.86 in paddy straw, 16.98 in maize stover and 22.70 in sugarcane trash at 90 days after composting. Scanning electron microscope analysis showed modification in the surface structure of the degraded material. Further, lignocelluloytic consortium was tested for its degradation potential when amended with cow dung, FYM @ 10%, urea (@ 2% & 4%), human urine (1:1 & 2:1 dilution) using paddy straw, sugarcane trash and maize stover substrates. The results revealed that, in all substrates amended with cow dung @10%, FYM and urea @4% (T6) showed faster degradation and found statically on par when substrates were amended with urea @2% (T5), human urine of dilution 1:1 (T7) and 1:2 (T8) where cow dung and FYM were common. Hence, urea @2% and human urine @1:2 dilution were optimized for large scale compost production of all the three substrates along with cow dung @10%, FYM @10% and consortia. In a field study, 100% RDF + urea enriched paddy straw compost (T4) produced better baby corn growth and yield and improved soil biological parameters.
