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.

    Establishment of rainfall runoff Relationship under different land Surface conditions in eastern Dryzone of Karnataka
    (University of Agricultural Sciences, Bangalore, 2023-01-07) Shivaraj, Balooragi; Ashoka, H. G.
    An experiment was conducted during the Kharif season of 2021 to establish rainfall runoff relationship under different land surface condition at the AICRPDA, GKVK, UAS, Bengaluru. The different land surface conditions includes the conservation furrows along with vegetative barriers viz., Nase and Khus grass as an inter terrace management grown across the slope. During kharif season pigeon pea crop was taken to know the effect of moisture conservation measures on crop productivity. Among the two different vegetative barriers, Nase grass (T1) was found to be most effective in controlling runoff and conserving soil moisture. The average runoff generated through the Nase grass (T1) and Khus grass (T̄2) was 8.34% (81.08 mm) and 10.57% (102.70 mm) respectively, than the control (T3) of 12.34% (121.23 mm). The average runoff generated through protected cultivation (T4) was 90.38% (992.01mm) of total rainfall of 1097.60 mm. The higher regression coefficient of 0.9998 was observed in protected cultivation. The lowest regression coefficient 0.9045, 0.9312 and 0.9491 was observed in the Nase grass (T1), Khus grass (T2) and control (T3) respectively. Similarly, the highest moisture conserved at Nase grass was 15.54%, 18.44%, 20.52% and 21.66% at 15cm, 30cm, 45cm and 60cm respectively. At the time of harvest higher plant height (224.13 cm), number of branches (26.37), leaf area (12997 cm2 plant-1), grain yield (1550 kg ha-1), net returns (41978 Rs ha-1) and B:C ratio (2.18) was found to be in Nase grass vegetative barrier plot, due to the conservation of more moisture and reduced runoff

    STUDIES ON IN-SITU MOISTURE CONSERVATION WITH SUBSOILER IN FINGER MILLET AND GROUNDNUT BASED INTERCROPPING SYSTEMS
    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK BENGALURU, 2019-09-23) MADAN KUMAR, M.; Murukannappa
    In the present scenario, hard pan formed at the subsoil has declined the productivity in the dryland which can be resolved by subsoiler which is used for breaking the compacted soil, thereby conserving more moisture. To know the effect of subsoiler, an experiment was conducted at AICRP on dryland agriculture on moisture conservation, mainly consisting main plot as cropping system viz., C1-fingermillet+pigeonpea (8:2) and C2-groundnut+pigeonpea (8:2) intercropping systems and subplot consisting of S1- Subsoiling at 2m interval, S2-Subsoiling at 4m interval, S3-Subsoiling at 2m interval+FYM, S4-Subsoiling at 4m interval+FYM and S5-Control with 3 replications. In the main plot, parameters like moisture and infiltration rate were found higher with GN+PP (8:2) 60 cm due to ground covering of groundnut. Among the subplot, Subsoiling at 2m interval+FYM found to conserve the higher moisture, higher infiltration, plant height, dry matter content and yield parameters due to subsoiling and application of FYM. Lower soil compaction was found in S1 and S3 treatments due to subsoiling. B:C ratio was higher in C1 due to lower cost of cultivation and S3 showed higher gross returns, however B:C ratio was higher in S1 was mainly because application of FYM in S3 increased the cost of cultivation decreasing the B:C ratio. Overall, C1 showed higher net returns while, S3 found better for better moisture conservation and nutrient availability and S1 were found to be the best treatment in terms of profitability.
