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 RESPONSE OF KHARIF POP SORGHUM {Sorghum bicolor (L.) Moench) GENOTYPES TO FARMYARD MANURE AND MINERAL FERTILIZERS IN BLACK SOIL UNDER RAINFED CONDITIONS(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-02) NEGALUR, RAJEEVAKUMAR B.; KACHAPUR, M. D.A field experiment was eondueted to study the response of uharif pop sorghum genotypes to FYM and mineral fertilizers in black soil under rainfed conditions at Main Research Station, Dharwad during rainy season of 2000. The experiment was laid out in randomized block design with 15 treatments. Application of RDF (80 : 40 : 40 kg N : : Kp ha-1) + FYM (5 t ha-1) to the genotype Inamhongal -1 has recorded higher leaf area and LAI at 120 DAS (48.60 dmVplant and 5.40, respectively). Higher total dry matter (TDM) production (184.65 g/ plant) was recorded at harvest with RDF + FYM application. Higher dry matter accumulation in leaves (42.10 9/plant), stem (88.86 g/plant) and ear (69.1 g/plant) was recorded at 120 DAS with the RDF + FYM treatment. Highest peduncle length was noticed with the Inemhongal-lboth at 120 DAS and at harvest (21.8 and 31.5 em, respectively). Inamhongal-1 has recorded higher ear head length and girth (27.7 and 12.4 em, respectively). Grain number per ear head was higher with application of RDF + FYM to Inamhongal-1 genotype (1432.3). Grain weight per plant, test weight and number of raehes per ear head were higher with the genotype Inamhongal-1. Grain yield was higher (1356 kg/ha) with Inamhongal-1 and was lower with Uppinbetageri-1 (910 kg/ ha). Stover yield was also higher with Inamhongal-1 (24.5 t/ha) but was lower with Gadag-1 (9.5 t/ha). Gadag-1 genotype has recorded higher 111 (0.107), maximum protein per cent in grains (7.55) and higher uptake of N,P and K (116.2, 25.1 and 154.3 kg/ha, respectively). Combined application of RDF + FYM recorded higher available N, P2O5, KjO and organic carbon at harvest (156.62,26.27,265.65 and 0.617, respectively) in the soil. Application of 50% RDF + FYM recorded higher popping percentage, expansion volume of pop and flake size (78.00, 17.89 ml/g and 0.44 ml, respectively). Protein per cent in pop was higher with lnomhongal-1 (7.40). Net returns were higher with Inamhongal-1 holh in case ol giains and pops (Rs. 21063/ha and Rs. 30463 /ha, respectively) with the application of RDF + FYM.ThesisItem Open Access INTEGRATED NUTRIENT MANAGEMENT IN IRRIGATED WHEAT (Triticum aestivum L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-02) HAILE, BEKELE; PATIL, V. C.A liold cxpcriinciiL was conducLcd Lo sludy Ihe elTect of intcgraLed nutrient management in irrigated wheat (Triticum aestivum L.) at the Main Research Station, University of Agricultural Sciences, Dharwad during the post-rainy season of 1999-2000. The experiment was laid out in a completely randomized block design with four replications. All growth parameters observed at different growth stages were significantly influenced by the treatments except plant height and dry matter accumulation in stem at 30 DAS. Application of 75 and 50 per cent of RDF along with organics resulted in similar plant height, effective tillers and ear dry matter accumulation as obtained with 100 per cent RDF + FYM + ZnS04. At 30 and 60 DAS, LAI ^d number of shoots did not differ due to treatments except control and organics alone. However, at later stages application of 100 per cent RDF + FYM + ZnS04 resulted in higher LAI than other treatments except 75 per cent RDF + organics (0.85) at harvest. Significantly higher total dry matter accumulation (20.18) was observed with addition of 100 per cent RDF + FYM + ZnS04 at 30 DAS and it was at par with 75 per cent RDF + organics at later stages. Grain yield, number of grains and grain weight per ear did not differ among treatments that received 100 per cent RDF + FYM + ZnS04, 75 and 50 per cent of RDF + organics. Substitution of 25 to 75 per cent of RDF with organics resulted in similar ear length, 1000 grain weight, straw yield, grain to straw ratio and harvest index as with 100 per cent RDF + FYM + ZnS04. Significantly higher grain N (1.97%) and protein content (12.3%) than other treatments was observed with application of 100 per cent RDF + FYM + ZnS04 and it was at par with 75 and 50 per cent of RDF + organics. Grain fat and crude fibre content did not differ significantly due to treatments. The treatments that received 100 per cent RDF + FYM + ZnS04 and 75, 50 and 25 per cent of RDF with organics were at par with respect to N uptake. Substitution of 25 to 50 per cent of RDF with organics and 100 per cent RDF + FYM + ZnS04 (26.1 kg/ha) resulted in similar P uptalThesisItem Open Access PHOSPHORUS MANAGEMENT IN GROUNDNUT (Arachis hypogaea L.) USING SLUDGE IN VERTISOLS OF NORTHERN TRANSITIONAL TRACT OF KARNATAKA(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-02) GANGANNA; PALLED, Y. B.A field experiment was conducted on black soils at Main Research Station, University of Agriculture Sciences, Dharwad, during kharif 1999-2000 to study the effect of phosphorus management practices iii groundnut using sludge. The treatments consisted of two sources of phosphorus (sludge and SSP), FYM and phosphorus solubilizer (Pseudomonas stnata). The experiment was laid out in randomised block design with three replications. The pod yield of groundnut differed significantly with different treatments. The maximum pod yield (45.9 q/ha) was recorded in treatment that received 50% phosphorus through sludge plus 50% phosphorus through SSP along with FYM and phosphorus solubilizer and was on par with 100% phosphorus through SSP alone. The kernel yield and oil yield per ha also differed significantly by different treatments. The highest kernel yield (33.33 q/ha) and oil yield (15.33 q/ha) were obtained in treatment receiving 50% phosphorus through sludge plus 50% phosphorus through SSP along with FYM and phosphorus solubilizer. The values of growth components (Plant height, number of branches per plant, leaf area per plant, LAI and dry matter production and its distribution in different parts) and yield components (number of pods per plant, pod weight per plant and 100 pod weight) were also higher with the application of sludge and SSP in the ratio of 1:1 and 3:1 along with FYM and phosphorus solubilizer. Maximum net income (Rs. 46,012/ha) was realised in treatment receiving sludge and SSP in the ratio of 1:1 along with FYM and phosphorus solubilizer. Higher B:C ratio was recorded in treatment which received sludge and SSP in the ratio of 3:1 along with phosphorus solubilizer. Significantly lower fluoride content in groundnut kernel (3.02 ppm) was found in control treatment which received 100% SSP alone compared to other treatments.
