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.

    Dynamics of boron in soils and response of maize-cowpea to graded levels of boron in central dry zone of Karnataka
    (University of Agricultural Sciences, Bengaluru, 2014-03-10) H, Mohamed saqeebulla; C. T, Subbarayappa
    An investigation was carried out to make a systematic survey of the boron status in soils of Chitradurga district. Soils were characterized for various physical, electro-chemical properties, boron fractionation and adsorption behaviour. A field experiment was conducted on boron deficient soil to evaluate the effect of boron sources and levels on growth and yield and nutrient concentration of maize and residual effect of boron on cowpea crop. The experiment was laid out in a split-split plot design with twelve treatments and replicated thrice. Soils of the study area are loamy to sandy clay loam in texture and acidic to alkaline in reaction (4.74-9.60). Soils were low to medium in organic carbon, NPK and available sulphur was deficient. Hot water soluble boron ranged from 0.02 to 1.98 mg kg-1 and 46.66 per cent of soils were deficient. The fractions of the boron in soils reveal their relative dominance in the order of RES-B>Org-B>Ox-B>Sp-B>Rs-B. The maximum adsorption capacity of boron ranged from 21.74 to 1.51 mg kg-1. The bonding energy coefficient of soil was recorded highest in Avinahatti followed by Anchibarahatti soil. Application of rec. FYM+NPK+8 kg/ha B through granubor significantly improved the growth, yield (6.28 t ha-1), nutrient content and uptake in grain and stover of maize than borax application. The hot water soluble boron at harvest increased linearly with increase in the levels of boron. The highest residual cowpea grain yield (4.00 q ha-1), nutrient content and uptake was recorded with application of FYM+NPK+8 kg/ha B as granubor than borax. The boron fractions at harvest of crops increase linearly with the sources and levels of B addition. The correlation studies indicated that available B had positive significant correlation with RS-B, SP-B, OX-B, Org-B, RES-B, grain, stover/hulm yield, grain and stover/hulm B content.
