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.

    UTILIZATION OF PRODUCTS OBTAINED FROM PYROLYSIS OF PADDY STRAW
    (University of Agricultural Sciences, Bangalore, 2021-10-31) ANUSHA, B. S.; RINKU, VERMA
    A poly bag study was undertaken during December 2020 at RIOF, UAS, GKVK Bangalore 65. Pyrolysis of paddy straw was done at 500oC without using catalyst, 2.29 kg of biochar containing 0.41% Nitrogen, 0.04% Phosphorus, 3.83% Potassium, 12 ml Bio oil which is rich in phenol (27.23%) and 101.48 L of syngas was obtained. Further the biochar was used in packet experiment to evaluate the influence of biochar on performance of Field bean using Completely Randomized Design with twenty-four treatments replicated twice. The results revealed that application of 25 tons of biochar + FYM + Vermicompost + Ganajeevamrutha recorded higher growth parameters viz., plant height (66 cm), number of leaves (80), number of branches (14) and yield attributes like number of pods/plant (16) and pod weight/plant (21g). Application of biochar recorded significant improvement in water holding capacity (42%) of the soil. The soil pH (9.5), electrical conductivity (0.19 dSm-1) and organic carbon (6.42 g kg-1) significantly increased, however decrease in bulk density (1.34 Mg m-3) of soil was noticed in the same treatment. There was significant increase in Nitrogen (297 kg ha-1), Phosphorus (63.25 kg ha-1) and Potassium (173.95 kg ha-1) in post-harvest soil. The Iron and Manganese concentration decreased and increase in Zinc and Copper concentration in post-harvest soil was observed.
