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 PHOSPHORUS ENRICHED ORGANIC MANURES ON P-AVAILABILITY TO MAIZE - BENGAL GRAM CROPPING SEQUENCE IN VERTISOL
    (UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 2001-08-09) BASAVARAJ; MANJUNATHAIAH, H. M.
    A field experiment was conducted at Main Research Station, University of Agricultural Sciences, Dharwad on chromic haplusterts during kharif and rabi of 1997-98 and 1998-99, to investigate the effect of phosphorus enriched organic manures on soil properties and crop yield of maize and their residual effect on bengal gram under irrigated condition. The experiment consisted of three main plots: no P-fertilizcr, HRDF-P (37.5 kg P205/ha) and 100% RDF-P (75 kg P205/ha) and 9 sub-plots: no organic manure, FYM @ 5 t/ha, vermicompost @ 2 t/ha, biogas slurry @ 3 t/ha, poultry manure @ 2 t/ha, P-enriched FYM @ 2.5 t/ha, P-enriched vermicompost @ 1 t/ha, P-enriched biogas slurry @ 1.5 t/ha and Penriched poultry manure @ It/ha, with 3 replications in split plot design. Application of P-enriched organic manures at all levels of Pfertilizers, either individually or in combination significantly increased the growth and yield of maize and bengal gram. The highest grain yields of maize (59.80 q/ha) and bengal gram (24.30 q/ha) were obtained due to addition of P-enriched poultry manure @ 1 t/ha plus 100 % RDF-P, which were found superior to all other treatments. The increase in yield over control (no organic manure) was 27.50 and 118.92 % in maize and bengal gram, respectively. Higher uptake of N, P, K and Zn by both the crops were observed due to increased availability of these nutrients in soil with the addition of P-enriched organic manures and P-fertilizer. Among different P-enriched organic manures, poultry manure gave highest uptake and available status of N, P, K and Zn. All the added P-enriched organic manures and P-fertilizer in soil significantly decreased soil pH and increased EC and organic carbon content. In P-enriched organic manures at all levels of P-fertilizer, either individually or in combination, significantly increased the transformation of applied P into Al-P, Fe-P, Ca-P, Red-Sol-P, Occl-P, total mineral-P and organic-P and similar trend was also noticed in residual effect on bengal gram. Addition of P-enriched poultry manure with HRDF-P found beneficial and yielded higher monetary returns (Rs.49318.0/ha) and B:C ratio (6.19) from maize-bengal gram cropping system.
