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 EVALUATION OF SULFOSULFURON AS PRE AND POST EMERGENCE HERBICIDE IN WHEAT UNDER IRRIGATED BLACK SOIL(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-02) MANGANAVAR, SATISH S.; PATIL, B.N.A field experiment was conducted to evaluate sulfosulfuron as pre and post emergence herbicide in wheat under irrigated black soil at All India Coordinated Wheat Improvement Project, Main Research Station, University of Agricultural Sciences, Dharwad during rabi 1999-2000. The experiment was laidout by adopting randomi2ed complete block design with 18 treatments and 3 replications. The predominant weeds observed in experimental site include, Commelina benghalensis, Cynodon dactylon, Cyperus rottmdns, Dine bra retroflexa and Echinocloa colonum among the monocots and among dicots, Alternanthera sessilis, Amaranthus sp., Bidens pilosa, Lactnca rnncinata, Lagasca mollis, Parthenium hysterophorus, Phyllanthus nruri and Portulaca oleracea. Sulfosulfuron @ 50 g ha-1 irrespective of its application timings, recorded significantly lower population and dry matter of both grassy and broad leaved weeds. However sulfosulfuron @ 50 g ha-1 applied as pre emergence herbicide recorded lowest weed population and dry weight and was on par with other pre emergence treatments. Highest weed control efficiency was noticed with the application of sulfosulfuron @ 50 g ha-1 applied as pre emergence at all the stages of crop growth as compared to 2,4-D Na salt @ 2500 g ha-1 applied at 30 DAS. Among post emergence treatments, sulfosulfuron @ 50 g ha-1 applied at 20 and 30 DAS and sulfosulfuron and 2,4-D EE @ 20 and 450 g ha-1 applied as pre emergence and at 30 DAS recorded higher weed control efficiency at all the crop growth stages. Sulfosulfuron @ 50 g ha-1 applied as pre emergence herbicide recorded maximum grain yield. The increase in yield due to application of sulfosulfuron @ 50 g ha-1 as pre emergence and at 20 DAS was to an extent of 23.88 and 18.00 per cent respectively over unweeded control. Sulfosulfuron @ 15 to 25 g ha-1 applied as pre emergence herbicide was found most effective in control of both monocot and diocot weeds and recorded higher grain yields vis-a-vis higher benefit : cost ratio. Sulfosulfuron did not exhibit any phytotoxic effect on crop growth upto 50 g ha-1 either as pre or post emergence application.ThesisItem Open Access EFFECT OF PLANT GEOMETRY ON GROWTH AND YIELD OF PIGEONPEA GENOTYPES IN VERTISOLS OF NORTHERN TRANSITIONAL ZONE OF KARNATAKA(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-02) ANTARAVALLI, MANJUNATH B.; HALIKATTI, S. I.A field experiment was conducted during Kharif, 1999 at Main Research Station, Dharwad with two pigeonpea genotypes and seven planting geometries (population). The genotypes, Maruti (1469 kg/ha) and PET-3-19 (1445 kg/ha) recorded on par grain yield, yield attributes viz., number of pods per plant, number of seeds per pod, pod weight per plant, seed yield per plant, 100-seed weight, harvest index and seed protein content. While, few growth characters viz., total number of branches, dry matter accumulation in leaves, total dry matter production, plant spread per plant and light transmission ratio were found significant only at certain stages of growth. But, there was significant difference in plant height, days to flower initiation, 50 per cent flowering and physiological maturity, the highest being with PET-3-19. The geometry had significant effect on all the growth and yield attributes. A geometry of 120 cm X 30 cm with a population of 27,777 plants per ha recorded the highest yield (1544 kg/ha) and yield attributes viz., number of pods per plant (155.7), number of seeds per pod (3.2), pod weight per plant (99.033 g), seed yield per plant (53.90 g), 100-seed weight (9.130 g) and harvest index (27.62 %). It also recorded the highest per plant number of primary, secondary and total branches, dry matter accumulation in leaves, stem and reproductive parts, plant spread and LTR. But, the plant height, LAI, LAD and flower drop were highest with a population of 83,333 plants per ha with the geometry of 120 cm X 10 cm and 60 cm X 20 cm. Thus, it can be concluded that the genotype Maruti in a geometry of 120 cm X 30 cm with a population of 27,777 plants per ha is optimum to get higher yield and net return in vertisols of Northern Transitional Zone of Karnataka.ThesisItem Open Access EFFECT OF CROP GEOMETRY, DATE OF PLANTING AND LEVELS OF NITROGEN ON GROWTH AND YIELD OF POTATO(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-02) YENAGI, BASAVARAJ S.; MELI, S.S.ThesisItem Open Access RESPONSE OF CHICKPEA (Cicer arietinum L.) GENOTYPES TO IRRIGATION SCHEDULES AND NAA SPRAY IN VERTISOLS OF NORTHERN KARNATAKA(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-02) PRAKASH, D. U.; JANAWADE, Dr. A. D.A field experiment was conducted at Main Research Station, University of Agricultural Sciences, Dharwad on medium black soil to study the "Response of chickpea genotypes to irrigation schedules and NAA spray in Vertisols of northern Karnataka" during rabi 1999. The experiment was laidout in split plot design with three replications. There were 18 treatment combinations consisting of 3 irrigation schedules (0.4, 0.6 and 0.8 IW/CPE ratios) as main plots, and 2 genotypes {desi variety Annegeri-1 and kabuli variety ICCV-2) and 3 NAA spray treatments (no spray, 20 ppm spray and 30 ppm spray) as sub-plots. Irrigation scheduling at 0.6 IW/CPE ratio recorded significantly higher seed yield (7.9 and 17.6%) over 0.8 and 0.4 IW/CPE ratio, respectively. Among the genotypes, desi variety-Annegeri-1 outyielded kabuli variety-ICCV-2 by 27 per cent. The spray of NAA @ 20 ppm increased the seed yield of chickpea significantly over 30 ppm spray and no spray. This was the consequent effect of significantly improved growth and yield parameters. Irrigation scheduling at 0.6 IW/CPE ratio, desi variety-Annegeri-1 and 20 ppm NAA spray recorded higher water use efficiency. Irrigation scheduling at 0.6 IW/CPE ratio with 20 ppm NAA spray to desi variety recorded higher net returns and B:C ratio. Based on the results it could be concluded that scheduling of irrigation at 0.6 IW/CPE ratio to desi variety-Annegeri-1 with 20 ppm NAA spray was economically feasible for realising higher seed yield and net returns in chickpea in vertisols of Northern Karnataka.ThesisItem Open Access STUDIES ON INTERCROPPING OF PIGEONPEA IN RAINFED COTTON(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-02) KOLHAR, B. C.; HALEMANI, H. L.A field experiment was conducted on medium deep black soil under rainfed condition at the Agricultural Research Station, Dharwad Farm, during the kharif season of 1998-99 to study the effect of row proportions of cotton and pigeonpea (2:1, 3:1, 4:2 and 6:2) and pigeonpea population (50 and 75 per cent of sole crop) on intercropping systems. Sole crops of cotton and pigeonpea were also raised. Sole crop of cotton and pigeonpea realised significantly higher 5deld than intercropping system. The seed cotton 3deld produced under 6:2 row proportion (1059 kg/ha) was significantly more than 2:1 (664 kg/ha), 3:1 (728 kg/ha) and 4:2 (823 kg/ha) row proportions. On the contrary, the seed yield of pigeonpea under 2:1 (1464 kg/ha), 4:2 (1463 kg/ha) and 3:1 (1421 kg/ha) row proportions were significantly higher than 6:2 row proportion (992 kg/ha). However, pigeonpea population levels and interaction effects had no significant effect on the cotton and pigeonpea ykld. Based on Area Time Equivalent (ATER) Ratio, cotton and pigeonpea intercropping found to be 18 per cent more efficient in utilising land area and time than of the sole crops. Mean of intercropping systems, intercropping of cotton with pigeonpea has recorded the lower net returns (Rs.l7,236/ha) and B:C ratio (L04) as compared to sole cotton (Rs.20,380/ha and 1.40, respectively). The net return and B:C ratio derived from 4:2 and 6:2 were higher over 2:1 and 3:1 row proportions. Among the cropping systems, highest gross and net returns were obtained with intercropping of cotton and pigeonpea with 6:2 row proportions at 100:50 per cent plant population followed by intercropping system with 4:2 row proportions at 100:75 per cent plant population and sole cotton. These systems gave more gross, net returns and B:C ratio than sole pigeonpea. 4 From the results of this investigation it is concluded that sole cotton as well as intercropping of cotton and pigeonpea with 6:2 proportions at 100:50 per cent plant population were better cropping systems than sole pigeonpea under rainfed condition.ThesisItem Open Access RESPONSE OF HYBRID MAIZE (Zea mays L.) TO ROW APPLICATION OF ORGANICS AND NITROGEN IN TRANSITIONAL TRACT OF NORTHERN KARNATAKA(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-02) VENKATESH, R.; PALLED, Y.RA field experiment was conducted to study the 'Response of hybrid maize to row application of organics and nitrogen in Transitional Tract of Northern Kamataka' at Main Research Station, Dharwad on medium black soil during kharif, 1997. Treatment combinations consisted of three organic sources (FYM @ 1 t/ha, poultry manure @ 1 t/ha and vermicompost @ 1 t/ha) and three nitrogen levels (100 kg N/ha, 150 kg N/ha and 200 kg N/ha). Grain and stover yield of maize were significantly higher at 200 kg N/ha (52.01 q/ha and 8.16 t/ha, respectively) over other nitrogen levels. Among the organic sources, row application of poultry manure recorded significantly higher grain and stover yield (53.53 q/ha and 8.24 t/ha). The combination of row application of poultry manure @ 1 t/ha and 200 kg N/ha recorded significantly higher grain yield (57.57 q/ha) over other combinations. The increase in grain yield of maize at row application of poultry manure with 200 kg N/ha was to an extent of 28.59 per cent over no organics. Application of 200 kg N/ha with row application of poultry manure recorded significantly higher N uptake (284.27 kg/ha) by maize crop and available nitrogen in soil after harvest (187.57 kg/ha). Maximum net returns (17679 Rs/ha) were realized by 200 kg N/ha with row application of poultry manure. Maximum B:C ratio (2.45) was noticed in 150 kg N/ha with row application of poultry manure.ThesisItem Open Access THE PERFORMANCE OF IMIDAZOLINONE HERBICIDES FOR WEED MANAGEMENT IN TFRTGATED SOYBEAN (Glycine max L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2000-10-20) DINESH KUMAR, Y.K.; VENUGOPAL, Dr.N.ThesisItem Open Access INTEGRATED WEED MANAGEMENT IN GARLIC (AI hum sativum L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2000-10-20) KUIIAR NAIK, A.H.; Muniyappa, Dr.T.V.ThesisItem Open Access RESPONSES OF COWPEA (Vigna unguiculata (L. ; walp) TO SOURCES OF PHOSPHORUS AND ZINC LEVELS(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2000-09-07) PREM KUMAR, C.; NAGARAJU, A.P.
