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.

    STUDY OF RAINFALL VARIABILITY ON GROUNDWATER RECHARGE AND PROPOSE RAINWATER HARVESTING STRUCTURES AT YAREHALLI MICRO-WATERSHED OF DAVANAGERE DISTRICT
    (UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 2020-12-02) NAGARAJ; Rajashekarappa, K. S.
    Geospatial technique were used for land and water management action plan for Yarehalli micro-watershed lies between 750 51' 37.585'' to 750 53' 29.93'' E longitudes and 130 58' 59.959'' to 140 1' 3.722'' N latitudes in Davanagere district of Karnataka. Arc GIS software was used in evaluation of morphological characteristics in micro-watershed. The present study reveals that drainage pattern was dendritic with trunk order 4. The area, maximum length and width of the micro-watershed are 977 ha, 4.40 km and 2.20 km, respectively. The mean value of bifurcation ratio was 3.23, it indicates micro-watershed has been suffered less structural disturbance. The value of drainage density 2.31 km km−2 which indicated that, the region is having permeable subsoil material. The value of form factor indicates micro-watershed is approaching towards elongated shape of watershed. The study was used to estimate groundwater recharge and draft studies were conducted at Yarehalli micro-watershed during 2018-2019. The studies revealed that thetotal draft of groundwater was found to be 29,87,622 m3, against the total recharge of 2,48,105 m3 with the groundwater extractions being 12 times more than the recharge. The result reveals that, 57.31 per cent of the total area is ideal for constructing check dam, 23.17 per cent for farm pond, 8.57 per cent for percolation pond and 1.12 per cent for gully plug. Which helps in sustainable development of the natural resource and socio-economical life of the farmers in micro-watershed.

    ESTIMATION OF SURFACE RUNOFF BY NRCS CURVE NUMBER METHOD USING GIS AND REMOTE SENSING IN YAREHALLI MICROWATERSHED OF DAVANAGERE DISTRICT.
    (University of Agricultural Sciences, Bangalore, 2021-12-03) BASAVAREDDY; B. C. Ravikumar
    The relationship between rainfall and runoff for a watershed is important in various activities of a water resources development and management. The transformation of rainfall to runoff is highly complex, dynamic, nonlinear & exhibits temporal and spatial variability. A Geospatial technique was used for surface runoff estimation in Yarehalli micro-watershed which lies between 75° 51' 38" to 75 ° 53' 30" E longitudes and 13° 58' 59’ to the 140 01' 04" N latitudes in Davanagere district of Karnataka, India. The study reveals that, drainage pattern is dendritic with trunk order 2. The area, maximum length and width of the micro-watershed are 761.47 ha, 3.96 km and 2.92 km respectively. The mean value of bifurcation ratio is 14, it indicates micro-watershed has suffered less structural disturbance and the value of formfactor indicates micro-watershed is approaching towards elongated shape. The value of drainage density is 1.64 km km-2 which indicates the region is having permeable sub-soil material. NRCS Curve Number method was used to estimate the surface runoff which uses watershed characteristics & 5-day antecedent rainfall. This method estimated the runoff as 255.56 mm and the total volume of runoff is 194.6 ha m in the year 2020, which is 18.66% of total volume of rainfall. These results help in planning, development and management of available water resources in the Yarehalli micro-watershed. November,
