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.

    Productivity of Soybean under Biofuel tree based Agroforestry system
    (University of Agricultural Sciences GKVK, Bangalore, 12-09-13) VISHWANATH, B R; NAGARAJAIAH, C
    The experiment was laid out in Randomized complete block design with eight treatments replicated thrice comprising of seven biofuel (oil seed bearing) tree species planted during 2008 at a spacing of 10 m between the plants with nine trees in each plot. Trees include Simarouba glauca, Melia dubia, Azadirachta indica, Melia azadirach, Pongamia pinnata, Madhuca latifolia and Calophyllum inophyllum. In the interspaces of trees, soybean was sown. The observation was made at two directions i.e., towards north and south of tree row and at two distances 0 – 2.5 m and 2.5 – 5 m from the base of each tree. These were compared with sole soybean. Sole crop soybean recorded significantly higher grain yield (1752 kg ha-1). The yield of soybean under agroforestry systems as compared to sole crop varied significantly by 10.0, 12.0, 12.9, 20.3, 26.2, 29.2 and 42.4 per cent in Madhuca, Calophyllum, Pongamia, Simarouba, Melia azadirach, Azadirachta indica and Melia dubia. Lower yield of soybean under agroforestry systems was attributed to significant reduction in growth and development of the soybean plants due to shading effect of trees. Soil fertility was significantly better in association with trees compared to open field. Soil organic carbon (0.60 per cent), available nitrogen (331.68 kg ha-1), available phosphorous (23.50 kg ha-1) and available potassium (304.67 kg ha-1) was significantly higher under agroforestry system. Among different biofuel tree based agroforestry systems, Madhuca, Calophyllum and Pongamia based agroforestry systems yielded high net returns (Rs. 52,115.00, Rs. 50,225.00 and Rs. 44,915.00 ha-1) with benefit to cost ratio of 2.66, 2.60 and 2.43 respectively.
