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.

    ASSESSMENT OF JAMUN (Syzygium cumini L.) BASED AGROFORESTRY SYSTEM
    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK BENGALURU, 2020-09-28) ARUNA, A. S.; NAGARAJAIAH, C.
    The litter dynamics were assessed in Jamun based Agroforestry system, Black gram, little millet, foxtail millet and finger millet were grown as intercrop from September to February. The total litter production was significantly higher in October (412.8 kg ha-1 ) and minimum in February (318.7 kg ha-1 ). The rate of litter decomposition was highest in October (0.191 k month-1 ). Nitrogen content in litter was maximum in November (0.637 %), Phosphorous and Potassium was maximum in September (0.415 %) and (0.293 %), respectively. pH was maximum at the depth of 30 cm (5.15 and 4.72), respectively in initial soils and after harvest of crop. EC also followed the same pattern, (99.97 mS m-1 and 72.81 mS m-1 ), respectively. Nitrogen and Phosphorous were highest in 30 cm layer (278.82 and 29.89 kg ha-1 , respectively), Potassium and Organic Carbon (OC) was highest in 45 cm layer (298.01 kg ha-1 and 0.72 %, respectively) in soils of after harvest of crop. Soil moisture percentage was 19.15 per cent more in intercrop soils compared to main crop soils throughout the crop growth. The total dry biomass of the trees was 140.33 t ha-1 . Carbon sequestration by Syzygium cumini was 63.143 t ha-1 . The maximum amount of carbon sequestered in soil at 45 cm depth was 45.48 Mg C ha-1 . All growth parameters of crops at 30, 60 DAS and harvest were more in the main crop compared to intercrops. The overall yield showed higher in main crop compare to intercrop (10.71 q ha-1 and 9.37 q ha-1 ), respectively
