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.

    Site specific nutrient management (SSNM) in aerobic rice (Oryza sativa L.) for yield maximization
    (University of Agricultural Sciences, Bengaluru, 2011-09-30) A. S, Police Patil; H.V, Nanjappa
    A field experiment entitled “site specific nutrient management in aerobic rice” was laid out in randomized complete block design including four aerobic rice genotypes (MAS 946-1, MAS-26, MAS-77 and Rasi) and three target yield (4.5, 5.5 and 6.5 t ha-1) levels conducted at ZARS, UAS, Bengaluru, during kharif season of 2009 and 2010. Among the aerobic rice genotypes, MAS 946-1 recorded significantly higher dry matter production and distribution, leaf area, LAI, number of productive tillers, panicle length and weight, number of grains and filled grains per panicle, test weight, grain yield per hill, lower sterility percentage, nutrient uptake, water productivity and grain yield (5903 kg ha-1) compared to MAS-77 (5322 kg ha-1), Rasi (5685 kg ha-1) followed by MAS-26 (5776 kg ha-1). Among the targeted yield levels, 6.5 t ha-1 (F3) recorded significantly higher growth and yield components, chlorophyll content, nutrient uptake and water productivity over 4.5 and 5.5 t ha-1 targeted yield levels. Grain yield increased progressively with increase in fertilizer level targeted for the higher yield level. Improvement in yield over their targeted yield level was in the order of 445, 71 kg ha-1 for 4.5 (4955 kg ha-1) and 5.5 (5571 kg ha-1) t ha-1 and for 6.5 (6488 kg ha-1) t ha-1 targeted yield level, shortfall of 12 kg ha-1. Higher gross returns (Rs. 65967/- ha-1), net returns (Rs. 44716 /- ha-1) and B:C ratio (3.11) was recorded in MAS 946-1 at 6.5 t ha-1 (F3) targeted yield. Quality parameters like grain length, L/B ratio, surface area index (SIA) was higher in MAS 77, but protein and amylose content was higher in MAS 946-1and was on par with MAS 26. Pot culture experiment results indicated that, among the genotypes MAS 946-1 recorded significantly longer root length, higher root dry weight, root volume, number of primary and secondary tillers, number of productive tillers, number of grains and filled grains per panicle, panicle length and weight, number of spikes, lower sterility percentage and grain yield per hill over MAS 77, Rasi and was on par with MAS 26. At different levels of fertilizer for targeted yield, 6.5 t ha-1 (F3) recorded longer root length, higher root number, dry weight and root volume and also yield and yield attributes over 4.5 and 5.5 t ha-1 targeted yield levels. Overall performance of genotype MAS 946-1 yielded superior over others at all the targeted yield levels closely followed by MAS 26.
