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.

    Effect of Non-edible Oil Cakes on Soil Nutrient Dynamics, Growth and Yield of Paddy (Oryza sativa L.) under Flooded conditions
    (University of Agricultural Sciences, Bangalore, 2010-07-10) AINUDDIN, AMANI; SRINIVASAMURTHY, C. A.
    The effect of non-edible oil cakes on soil nutrient dynamics, growth and yield of paddy under submerged conditions was investigated under green house conditions during November 2009 to February 2010. In this study, the soil selected from GKVK was sandy clay loam in texture, slightly acidic (pH 6.67), low in salt content and high in organic carbon (0.88 %). The available nitrogen, phosphorus and potassium contents were 225.00 kg ha-1, 28.30 kg ha-1 and 163.05 kg ha-1. The secondary and DTPA extractable micronutrients contents were sufficient. The treatments tried in the pot experiment were: 100 % N though three non edible oil cakes, 100 % N through non edible oil cakes with balance of P and K fertilizers, 50% N through cakes with 50% through fertilizer compared with recommended NPK fertilizers and FYM at 5 t ha-1 as control. Among the three non edible oil cakes, castor cake has lowest C : N ratio (9.3). All the cakes were rich in nitrogen and had appreciable amount of phosphorus and potassium in addition to secondary and micronutrients. In the green house experiment, at 30 days after application of 100 per cent N through castor, pongamia and jatropha cakes with balance of P and K through fertilizers was helpful in increasing the nutrients content and the reduction was marginal there after upto 120 days. Highest urease, acid and alkaline phosphatase activities (88.47 μg NH4 +-N g-1 hr-1, 33.25 μg PNP g-1 hr-1 and 35.48 μg PNP g-1 hr-1) were observed with application of 100 per cent N through pongamia cake with balance of P and K through fertilizers. Highest grain and straw yield (22.75 g pot-1 and 31.55 g pot-1) was obtained with application of 100 per cent N through pongamia cake and balance P and K through fertilizers. The nitrogen, phosphorus and potassium content and uptake by both grain and straw were significantly increased in all the treatments which received oil cakes. Treatment T7 which received 100% rec. N through pongamia cake and balance of P and K through fertilizers recorded higher N content (1.33 and 0.90 %, respectively in grain and straw), P (0.41and 0.31%) and K (0.83 and 0.61 %) and uptake of nitrogen, phosphorus and potassium (302.58, 93.28 and 188.83 mg pot-1 and 283.95, 97.81 and 192.46 mg pot-1, respectively by grains and straw) compared to others.
