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 ENRICHMENT OF BIOCHAR WITH HUMAN URINE AND ITS EFFECT ON SOIL PROPERTIES AND CROP GROWTH
    (University of Agricultural Sciences GKVK, Bangalore, 2013-07-28) GNYANARANJAN, PANIGRAHI; Srinivasamurthy, C A
    An incubation experiment was conducted under green house conditions at UAS, GKVK, Bangalore and a field experiment conducted at farmer’s field, Somsettyhalli, Doddballapur Taluk, Bangalore Rural district to study the effect of human urine enriched biochar on soil properties, growth and yield of French bean crop during summer 2013. The incubation experiment was conducted for preparation of nutrient rich biochar using human urine at different ratios (1:0.75, 1:1, 1:1.25, 1:1.5, 1:1.75 and 1:2). The increase in nutrient composition of coconut shell biochar was observed due to addition of human urine by preventing the loss of ammonia during incubation with H2SO4 treatment. The field experiment was conducted with nine treatments and three replications. The design was RCBD. Application of enriched biochar 1(1:2) to supply 50% recommended N and 50% N through fertilizer and 100% P and K through fertilizer (T4) has resulted in better plant growth and nutrient uptake by crop and also the vegetable yield of French bean. Significant differences in Physical, chemical and biological properties of soil were observed except bulk density and pH of the soil. Among chemical properties of soil, the Zn, Cu and B content did not differ significantly between the treatments. The findings of this study clearly showed that application of enriched biochar using human urine has resulted in better crop growth and yield of French bean, reflecting and confirming the improved nutrient availability in soil.
