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.

ThesisItem Open Access STUDIES ON METHOD OF PLANTING, IRRIGATION SCHEDULES, SOURCES AND LEVELS OF FERTILIZERS FOR FERTIGATION IN TOMATO (Lycopersicon esculentum Mill.) AND IT'S RESIDUAL EFFECT ON BABY CORN (Zea mays L.)"(University of Agricultural Sciences GKVK, Banglore, 2007-09-17) T.M. SOUMYA; Dr. B.K RAMACHANDRAPPAField experiments were conducted on the red sandy loam soils of Agronomy field unit, MRS, UAS, Bangalore during 2005 and 2006 to study the effect of method of planting, irrigation schedules, sources and levels of fertilizers for fertigation on growth, yield and quality of tomato and its residual effect on baby. The investigation involved two experiments. The first experiment comprised of three levels of drip irrigation (0.6, 0.8 and 1.0 Epan) and three methods of planting (normal, two rows paired system and four rows paired system) in randomized complete block design with three replications. The second experiment comprised of 12 treatment combinations with three levels of fertilizers (75, 100 and 125 % of Rec. NPK) and four sources of fertilizers (Urea, SSP, MOP; MAP, MOP; MAP, KNO3 and soil application of urea, SSP, MOP). After the harvest of tomato, baby com was grown to know the residual effect of fertigation without any additional inputs. Drip irrigation at 1.0 Epan with normal row system found superior in finit yield (109.05 t ha"'), growth and yield attributes of tomato and was on par with 0.8 Epan two rows paired system (106.12 t ha"'). The higher B: C ratio of 5.98 was obtained with 0.8 Epan two rows paired system. While, higher WUE (152.2 kg ha-mm ') was registered with 0.6 Epan two rows paired system. Fertigation with MAP, KNO3 at 125% rec. NPK was superior in total fmit yield (116.86 t ha'), growth and yield attributes of tomato closely followed by fertigation with Urea, SSP, MOP at 125% Rec. NPK (114.761 ha"'). Similar trend was noticed for fertilizer use efficiency, water use efficiency and nutrient uptake. Higher net returns ha"' was recorded in fertigation with Urea, SSP, MOP at 125 % Rec. NPK (Rs. 5,22,493/-) with the highest B: C ratio of 6.01. Baby com yield was significantly higher with the application of 125% Rec. NPK either through fertigation or through soil application to the previous tomato crop.ThesisItem Open Access STUDIES ON PRODUCTION POTENTIAL OF SWEET SORGHUM [Sorghum bicolor{L) Moench] GENOTYPES FOR GRAIN AND ETHANOL PRODUCTION AS INFLUENCED BY MANAGEMENT PRACTICES(University of Agricultural Sciences GKVK, Banglore, 2007-10-01) SANJEEVRADDI G.

K. SHANWAD; V. C. PATILAction plan preparation of Medak Nala watershed and impact assessment of Katangidda Nala watershed were carried out using remote sensing and GIS technologies. Satellite data of IRS- IC/ID for two seasons representing rabi (December 8 and 10, 2000 PAN + LISS III merged) and summer (March 15, 2001 LISS III) were used for preparing thematic maps and suggesting action plans for management of natural resources in Medak Nala watershed. Impact assessment of IWDP programme in Katangidda Nala watershed was done using IRS IC/ID data of LISS III image of December 11, 1997 (pre-treatment) and November 15, 2002 (post-treatment). The water and agriculture resources action plans of Medak Nala watershed were prepared by integrating the thematic maps such as land use/land cover, soil resource inventory, hydro-geomorphology, slope etc. The results indicated that the present land use of the watershed (5,169 ha, 42.58%) is under khan/crop followed by rabi crop area (2,814 ha, 23.18%) and land with scrub (2,280 ha, 18.78%). The 20 soil series of the watershed were classified under Inceptisols, Alfisols, Vertisols and Entisols. The hydro-geomorphology status of the watershed indicates that major area is under plateau moderately dissected (5,200 ha, 42.83%) followed by plateau slightly dissected (3,298 ha, 27.17%) and pediplain shallow (1,750 ha, 14.41%). The drainage network of the watershed resembles a dendritic pattern with drainage density of 2.16 km/sq. km. Based on these conditions, the watershed action plans were prepared. Water harvesting structures like boulder checks (257), check dams (62), nala bunds (10), miner irrigations tanks (2), soil conservation practices like contour farming, strip cropping and vegetative barriers were suggested. In agriculture action plan, agro-horticulture (5,575, ha, 45.93%) plays an important component followed by dryland- horticulture (2,725 ha, 22.45%) and fodder and fuel (2,290 ha, 18.86%).ThesisItem Open Access ACTION PLAN PREPARATION (Medak Nala) AND IMPACT ASSESSMENT (Katangldda Nala) OF WATERSHEDS IN GULBARGA DISTRICT USING REMOTE SENSING AND GIS TECHNOLOGIES(University of Agricultural Sciences GKVK, Banglore, 2007-10-01) U.
