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.

    EFFECT OF OYSTER MUSHROOMS SPENT SUBSTRATE ON ARBUSCULAR MYCORRIZAL SYMBIOSIS IN FINGER MILLET (Eleusine coracana G.)

    Spent mushroom substrate (SMS) is the substrate left after harvesting of mushrooms. Experiment was conducted to study the effect of oyster mushrooms spent substrate on Arbuscular mycorrhizae (AM) inoculum production. Hypsizygous ulmarius showed significantly higher yield and bio-efficiency. Hypsizygous ulmarius spent substrate shown higher nutrient content and narrow C: N ratio. Two oyster mushrooms (Pleurotus eous and Hypsizygus ulmarius) spent substrates were incorporated to pots with sterilized sand: soil as substrate and another set with unsterilized sand: soil as a substrate with AM fungi Glomus mosseae and Glomus fasciculatum. Sorghum was used as a host plant. Both the SMS were found to enhance mycorrhizal associations like percent root colonization and AM spores in substrate. Among the two SMS, Hypsizygus ulmarius SMS significantly increased number of spores and percent root colonization of Glomus fasciculatum compared to Pleurotus eous SMS. Increased mycorrhizal association characteristics was there in sterilized substrate compared to in unsterilized substate. The effect of oyster mushroom spent substrate and AM fungi with and without recommended dose of phosphorus in Finger millet, showed higher plant growth parameters like plant height, number of leaves, fresh and dry weight of shoots and roots in plants with H. ulmarius SMS and G. fasciculatum with RD of P. Plants with H. ulmarius and G. fasciculatum with RD of P showed higher uptake of N, P, K and Zn. Increased mycorrhizal associations like number of spores and per cent root colonization were found in plants with H. ulmarius SMS and G. fasciculatum
