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.

ThesisItem Open Access RESPONSE OF HYBRID MAIZE TO GRADED LEVELS OF CONCENTRATED MANURES AND MACRONUTRIENT FOLIAR SPRAY UNDER SURAHONNE (Calophyllum inophyllum L.) BASED AGRO-FORESTRY SYSTEM IN SOUTHERN TRANSITIONAL ZONE OF KARNATAKA(University of Agricultural Sciences, Bangalore, 2018-08-01) AKASHA, DANI; BHAIRAPPANAVAR, S.T.A field experiment was conducted during Kharif – 2017 at Biofuel park, Madenur, University of Agricultural Sciences, Bengaluru, on sandy loam soil. The Hybrid Hema (NAH-1137) was sown at the spacing of 60 cm x 30 cm under surahonne based agroforestry system. The experiment comprised of seven treatments with three replications laid out in RCBD. The investigation revealed that significantly higher kernel yield and stover yield (72.50 and 97.70 q ha-1, respectively) was recorded with application of recommended package (100:50:25) N, P2O5, K2O ha-1 + FYM @ 5 t ha-1. High yielding ability of the crop with this treatment was attributed to better yield components of cob weight (282.7 g), cob length (19.10 cm) and number of kernel rows cob-1 (16.53) as a result of higher growth components of plant height (241.4 cm), leaf area (8686 cm2) and total dry matter (497.0 g plant-1) and higher nutrient uptake (189.9, 46.82 and 162.0 kg N, P2O5 and K2O ha-1, respectively). The treatment also resulted in higher net returns (Rs. 70,472 ha-1) and B:C ratio (2.9) compared to other treatments. The study revealed that in this surahonne based agroforestry system there is no competition between surahonne and maize for basic resources.ThesisItem Open Access STANDARDIZATION OF SEED RATE AND TIME OF HARVEST FOR DIFFERENT FODDER CROPS UNDER HYDROPONIC FODDER PRODUCTION(University of Agricultural Sciences, Bangalore, 2018-08-01) GAGAN, R.C.; SHEKARA, B.G.Experiments were conducted to standardize the seed rate and time of harvest for different fodder crops viz., fodder maize, fodder bajra and fodder cowpea under hydroponic fodder production at ZARS, V.
