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.

    IMPACT OF BIO-FUEL PLANTATIONS ON SOIL MICROBIAL COMMUNITIES AND NUTRIENTS STATUS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2018-07-26) AGNES IMOYA PETER, OHIDE; PRASANNA, K. T.
    Presently the world has been confronted with an energy crisis due to depletion of fossil fuel reserves this leads to the search for an alternative fuel, such as biofuel. The field study on impact of bio-fuel plantations on soil microbial communities and nutrients status, was carried out in Bio-fuel Park, Madenur, Hassan district of Karnataka state India, during pre and post-monsoon of 2017-2018. With objectives to assess the status of microbial communities in soils as influenced by bio-fuel species and to compare the influence of different bio-fuel species on soil nutrient status. Results revealed that Abundance of microbial Population activities. Total bacteria, Cellulose decomposers, Azotobacter, PO4- solubilizing microorganism, were found to be significantly higher in pre-monsoon season, among biofuel species C.inophyllum and S. glacua influences higher and 0-15cm and 30- 45cm Soil depths was recorded higher microbes. In Enzymatic activities was significantly higher in pre-monsoon and among biofuel species, C. inophyllum A. indica, further in soil depths 15-30 cm. AMF spore density, show differences between two season, M. latifolia recorded significantly higher, and 30-45 cm soil depth. SMB in Post-monsoon significantly recorded high, among the trees species, S. glauca was highest in both Carbon and nitrogen. In soil chemical, soil pH and EC (Dsm-1) show significantly higher in post-monsoon season while O.C (%), Available N, P2O5, K2O was recoded significantly higher in pre-monsoon, in bio-fuel trees higher in C. inophyllum and S. glauca, soil depth was highly at15-30, 0- 15. Microbiologically characters week to best relation-ship in maintaining good soil health at landscape level. Pre-monsoon and C. inophyllum, S. glauca were positively impacting microbes and nutrients.
