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 Embargo STUDIES ON WEED DYNAMICS IN HYBRID MAIZE UNDER LONG TERM FERTILIZER EXPERIMENT (Zea mays. L)(2022-12-18) RAGHUVEER, M.; MURALI, K.A field experiment was conducted to study the weed dynamics in hybrid maize under long term fertilizer experiment (LTFE) during Rabi 2021 at All India Coordinated Research Project on LTFE, University of Agricultural Sciences, GKVK, Bangalore. The experiment was carried out in Randomized complete block design with three replications and eleven treatments of different doses of fertilizer along with FYM (10 t ha-1) and lime (500 kg ha-1). It was observed that among the grasses, Eleusine indica and Sorghum halapense were the most predominant weeds in the experimental field, whereas Commelina benghalensis, Alternantara spp., Oxalis latifolia and Ageratum conyzoides were most predominant broad leaved weeds. Oxalis latifolia was found only in the treatment receiving farm yard manure. Cyperus rotundus was the only species found in the experimental plot among sedges and it was found in lower doses of fertilizer application i.e., 50% NPK and control. Significant variation in weed density and biomass was recorded in different fertilizer treatment. Among different treatments, 100% NP recorded significantly higher weed density of 91.00 m-2 and 100% NPK + FYM + lime recorded significantly higher weed dry weight of 32.06 g m-2. Significantly lower weed density (40.67 m-2) and weed dry weight (8.92 g m-2) was recorded in control treatment (no fertilizers application). Application of 100% NPK + FYM + lime recorded significantly higher grain yield (6468 kg ha-1), straw yield (15126 kg ha-1), net returns (Rs. 88,066 ha-1) and B:C ratio (2.88).ThesisItem Open Access STUDIES ON PLANTING GEOMETRY OF PIGEONPEA AND SUITABLE INTERCROPS UNDER EASTERN DRY ZONE OF KARNATAKA (ZONE - V)(2021-12-23) LAXMAN, NAVI; ATHEEKUR REHMAN, H M.The field experiment entitled “Studies on planting geometry of pigeonpea and suitable intercrops under Eastern dry zone of Karnataka (Zone - V)” was conducted during Kharif, 2020 at ‘K’ Block, Zonal Agricultural Research Station, University of Agricultural Sciences, Gandhi Krishi Vigyan Kendra, Bengaluru to evaluate suitable intercrop (field bean, vegetable soybean and Chia) and planting geometry (normal and paired row planting with 4’ and 5’ between pairs) and its effect on growth, yield and economics of the intercropping. The experiment had 15 treatments which were replicated thrice in Randomised Complete Block Design. Higher pigeonpea seed and stalk yield (1813 and 4218 kg ha-1, respectively) was observed in paired row (120/60 cm x 30 cm) planting which was on par with intercropping of field bean (1:2) and vegetable soybean (1:3) under 120/60 x 30 cm paired row. The data revealed higher seed yield was mainly attributed to higher plant height, leaf area index, total dry matter production, no. of pods per plant and weight of pods per plant. In the intercropping system, paired row (120/60 cm x 30 cm) planting of pigeonpea with vegetable soybean (1:3) as intercrop recorded higher pigeonpea equivalent yield (1843 kg ha-1), net returns (Rs. 2,19,030 ha-1) and benefit:cost ratio (6.27) than rest spacing and intercropping treatments. However, significantly higher system indices like LER (1.69) and ATER (1.29) were recorded with paired row (150/60 cm x 45 cm) planting of pigeonpea with vegetable soybean (1:4) as intercrop in the intercropping system.ThesisItem Embargo EVALUATION OF DIFFERENT PIGEONPEA BASED INTERCROPPING SYSTEMS IN ALFISOLS FOR HIGHER PRODUCTIVITY(2022-12-09) DEVIKA, A. R.; ATHEEKUR REHMAN., H. MIn rainfed and dry regions of southern Karnataka, sole cropping is not much remunerative in the current scenario of climate change to meet the pulses requirement of growing population. Hence, the field experiment entitled “Evaluation of different pigeonpea based intercropping systems in Alfisols for higher productivity” was conducted during Kharif, 2021 at ‘K’ Block, ZARS, University of Agricultural Sciences, GKVK, Bengaluru to evaluate the most profitable intercrop (sweet corn, baby corn, sorghum, vegetable soybean,field bean, quinoa and grain amaranth) on growth, yield and economics of pigeonpea. The experiment was laid out in RCBD with 15 treatments each replicated thrice. Higher pigeonpea seed and stalk yield (852 and 1678 kg ha-1, respectively) was observed in pigeonpea + field bean (1:2) intercropping which was on par with vegetable soybean (1:2). The data revealed that higher seed yield was mainly attributed to higher plant height, leaf area, total dry matter production, no. of pods and pods weight per plant. However, planting of pigeonpea with sweet corn (1:2) as intercrop recorded higher pigeonpea equivalent yield (2724 kg ha-1), net returns (Rs. 2,96,750 ha-1) and benefit:cost ratio (4.91) than rest of the treatments. Whereas, higher system indices like Land Equivalent Ratio (1.43) and Area Time Equivalent Ratio (1.19) were recorded with pigeonpea + field bean (1:2) intercropping system.ThesisItem Embargo STUDIES ON WEED DYNAMICS IN HYBRID MAIZE UNDER LONG TERM FERTILIZER EXPERIMENT (Zea mays.
