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.

(NAH-2049 AND NAH-1137)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-10-06) SHASHIBHASKAR, M. S; Rajendra Prasad, STo standardize seed production technology VlZ., planting ratios, synchronization of parental lines, optimum screen size, storage potential and identify suitable morphological and DNA marker for hybrid purity testing experiments were carried out for newly released two single cross maize hybrids NAH-2049 (Nithyashree) and NAH-1137 (Hema) at NSP, GKVK and ZARS, VC Farm Mandya during 2010 to 2013. Between the hybrids, Hema (52.84 and 54.42q/ha) recorded the highest seed yield compared to Nithyashree (32.59 and 33.71q/ha) at GKVK and Mandya, respectively. However between the locations, GKVK (41.64 and 39.08q/ha) was found to be more suitable place for seed production than Mandya (39.08 and 38.55q/ha) during kharif and rabi, respectively. Hema seed production in 4: 1 ratio with combined application of ZnSQ4 and FeSQ4 10kg each recorded highest seed yield at GKVK (61.40 and 58.02q/ha) and Mandya (67.66 and 59.56q/ha), similarly in Nithyashree at GKVK (31.20 and 30.39q/ha) and Mandya (30.66 and 28 .19q/ ha) during kharif and rabi, respectively. Sowing of male parent by two days late than female parent in Nithyashree (34.20 and 36.30q/ha) and 2 days early sowing of male parent in Hema (59.97 and 59.6q/ha) showed significantly higher seed yields as well as quality during GKVK and Mandya, respectively. The grading of SKV-50 (98.58%), MAI-105 (98.14%), NAH-2049 (98.59%) and NAH-1137 (99,79%) by using sieve size 4.00mm(S) recorded highest seed recovery while NAI-137 (96.37%) by using 6.40mm(R). The seed treatment with Spinosad @ 0.04ml/kg of seed maintained minimum germination (80%) in SKV-O, NAI-137 and NAH- 2049 for ten months and MAI-105 for eight months of storage period. Polymorphic specific SSR markers viz., bnlgl 178 for NAH-2049 and phiOOl, phi435417 and umc2362 of NAH-1137 could be used for purity assessment of single cross millZe hybrids.ThesisItem Open Access INFLUENCE OF DIFFERENT GROWING CONDITIONS, MICRONUTRIENTS AND BIOSTIMULANT APPLICATION ON GROWTH, SEED YIELD AND QUALITY OF MARIGOLD (Tagetes erecta L.) cv ARKA BANGARA(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-09-23) SYED SALMAN, ARIF; Paramesh, RA field and laboratory experiments were conducted during Rabi 2014-15 at Department of Horticulture and Department of Seed Science and Technology, UAS, GKVK, Bengaluru.

Among the micronutrients and biostimulant spray of humic acid 0.2 % + FeSO4 0.5 % + ZnSO4 0.5 % at 30 and 45 DAT was recorded higher growth, seed yield and quality attributes viz., plant height (86.63 cm), number of branches (16.40), days to 50 per cent flowering (27.5), flowering duration (76.3 days), number of flower per plant (53.23), weight of the flowers per plant (573 g), flower diameter (6.61 cm), number of seeds per flower (147.83), seed yield per plot (162 g), seed yield per hectare (644 kg), seed recovery (84 %), germination (87.17 %), test weight (3.32 g), seedling length (12.29 cm) and seedling dry weight (12.14 mg) SVI-I and SVI-II (1071 and 1059, respectively) with lower electrical conductivity (0.162 dSm-1). Combination of open field condition with humic acid 0.2 % + FeSO4 0.5 % + ZnSO4 0.5 % at 30 and 45 DAT has recorded highest net return (Rs. 4,28,790) and highest benefit cost ratio (1:1.97).ThesisItem Open Access STUDIES ON CHARACTERIZATION OF GENOTYPES, SEED PRODUCTION AND SEED STORABILITY OF CLUSTER BEAN (Cyamopsis tetragonoloba (L.) Taub.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-20) UMESHA; Channakeshava, B. CStudies on characterization of genotypes, seed fortification and seed storage were conducted during kharif 2013 and 2014. The genotype PNB was classified as glabrous and remaining all genotypes as pubescent. The genotype GG-2 had white coloured flowers while other genotypes had light purple coloured flowers. Based on the zymogram of total soluble proteins, Region D (29.0 to 43.0 KD), E (20.0 to 29.0 KD), F (14.3 to 29.0 KD) and G (< 14.3 KD) were found more useful to distinguish most guar genotypes. The isozyme electrophoresis of esterase produced marked differences in the banding pattern that could be used for the identification of genotypes. Ten RAPD primers revealed 96.7 per cent polymorphism and primer OPQ-7 was found to be highly polymorphic. Highly distinct genotypes among the selected germplasm were IC-102853 with IC-116594 followed by IC-102853 with IC-116626; HG-365 with IC-116594. Among the genotypes, HG-365 is high yielding and suitable for Pavagada location. Seeds fortified with MgS04 @ 1 per cent recorded higher plant growth, seed yield and quality parameters. The improvement in seed yield due to MgS04 fortification was up to 22.21 per cent than control. Seeds treated with spinosad (0.04 ml/kg) and stored in super grain bag recorded higher germination (80.00 %) and other seed quality parameters at the end of 18 months of storage.ThesisItem Open Access STUDIES ON ASSOCIATION OF CAPSAICIN AND OLEORESIN CONTENTS ON INCIDENCE OF ANTHRACNOSE FRUIT ROT AND SEED QUALITY, AND VALIDATION OF DNA MARKERS LINKED TO PUNGENCY IN HOT PEPPER (Capsicum spp.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-08-06) NAGARAJU, K. S.; Rama Prasanna, K. PChilli (Capsicum annuum) in a highly valued spice cum cash crop. India is the largest producer of chilli in world. Anthracnose fruit rot caused by Colletotrichum Spp. is most serious disease reducing crop yield and quality. The present studies were carried out at the College of Agriculture, UAS, GKVK, Bengaluru. The results revealed that, days to fruiting ranged from (22-92 days), test weight (0.2972-9.74 g), germination (42-96 %), SVI-I (283-1489), seed protein (6.4-17.4 μg g-1), capsaicin (27-417 μg g-1), oleoresin 3- 23 %, ASTA colour value (2-16) and seed infection (0-82 %). The capsaicin content was negatively correlated with anthracnose disease and oleoresin was positively correlated with seed quality. Seed treatment with iprodine+ carbendizim @ 0.4 (%) eliminated anthracnose seed infection and improved seed quality. Storing dry chilli fruits in aluminium foils retained maximum seed germination (%) compared to vapour pervious containers. seed germination, test weight, TDH activity, seed protein, capsaicin and oleoresin decreased and seedling vigour and EC increased with storage period. Genotypes amplified single dominant band at 100 Kb with marker 7F/15R except AR-75, Byadagi Kaddi, Dyavanur Delux, G4, Gouribidanur Local, HMT-1 for pungency. A low pungent parent Paprika from C. annuum was hybridized to highly pungent parent C. chinense Assam Bhut Jolokia to produce inter specific hybrid and the six generation mean analysis revealed that, higher seedling length and the higher seedling emergence were predominantly under the control of genes with dominance effect and the dominance effect were unidirectional as evidenced by higher magnitudes of dominance gene effects.ThesisItem Open Access Influence of panchagavya on vegetable seed production of cowpea [Vigna unguiculata (L.) Walp] genotypes(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-31) SUMALATHA, G.M.; PARAMESH, RThe field and laboratory experiments were conducted at Regional Institute on Organic Farming and Department of Seed Science and Technology, UAS, GKVK, Bengaluru, during 2014-2015 to study, the influence of panchagavya on vegetable seed production of cowpea genotypes. The results revealed that PKB-4 recorded highest plant height (75.61 cm), number of branches (5.46) whereas, AV-5 recorded less number of days for 50 % flowering (53.67), highest germination (83.39 %), seedling vigour index-I (2718) seed yield planf1 (14.74 g), cleaned seed yield (1.22 Kg plof1 ). Among different concentrations, panchagavya at 5 % recorded significant improvement in plant height (85.94 cm), number of branches (6.47), less number of days for 50 % flowering (52.67 %), highest germination (88.88 %), seedling vigour index-I (3319), seed yield plant -I (14.80 g), cleaned seed yield (1.27 Kg plof1 ) compared to control. Among harvesting intervals, Subsequent formed pods showed better seed quality parameters viz., germination (84.22 %), seedling vigour index-I (3038), protein (16.78 %) compared to first formed pods. During accelerated ageing test (0 to IO days) after 10 days of test, genotype AV-5 recorded lower reduction of seed quality attributes like germination (3.85 %), seedling vigour index-I (33), total dehydrogenase activity (0.93 OD value), field emergence ( 1. 00 % ) compared . to other genotypes. The investigation revealed that panchagavya at 5 % with subsequent formed pods registered higher seed yield and quality parameters, Irrespective of the genotypes and panchagavya spray, accelerated ageing test revealed progressive decline in seed quality parameters as ageing period advanced.ThesisItem Open Access INFLUENCE OF NUTRIENT LEVELS AND TIME OF APPLICATION ON PLANT GROWTH, SEED YIELD AND QUALITY OF MAIZE (Zea mays L.)

The study comprised of four treatments and five replications. The results revealed that among the different nutrient levels of applications T3: 225:112.5:60 NPK kg ha-1 ( 20 % N, 100 % P & K at sowing, 25 % N at 4th leaf stage, 30 % N at 8th leaf stage, 20 % N at tasseling stage and 5 % N at grain filling stage) recorded highest plant height at 4 th leaf and 8 th leaf stage (24.04 and 50.32 cm), cob length (23.46 cm), cob width (3.65 cm), seed yield per cob (123.05 g), Bulk seed yield (26.68 q ha-1) , processed seed yield (24.38 q ha-1) and also recorded highest quality parameters like seed germination (95.60 %), SVI-1 and SVI-II (2570 and 6284). Accelerated ageing test was also conducted for these four treatments with a period of 0, 1, 2, 3, 4, 5, 6, days among these treatments highest field emergence (87.38 %) and germination (90.05 %) was recorded in T3. Economics and cost benefit ratio was calculated. The Marginal cost production and marginal return differed due to different nutrient level treatments. Marginal cost production and marginal return was highest in T3 (Rs 69,524 and Rs 1,49,430), while lowest was observed in control T4 (Rs 59,905 and Rs 1,06,710).ThesisItem Open Access DETERMINATION OF HEAVY METALS PRESENT IN PAINTS AND CLAY USED FOR IDOL MAKING AND THEIR EFFECT ON WATER AND SOIL QUALITY AND CROP GROWTH(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-10) BISWESWAR, GORAIN; Rama krishana, ParamaLakes are dynamic inland aquatic systems that support and maintain a balanced adaptive community of organisms having diverse species composition. All forms of life on the earth depend upon water for their existence. Life and water may be aptly said to be the two faces of a same coin. Tanks around Bangalore and elsewhere in the state of Karnataka were constructed mainly for harvesting rainwater for irrigation and drinking purpose by impounding the monsoon run-off from the valleys. Rapid industrialization and urbanization in recent years have undoubtedly affected lakes and tanks in the cities. Wetlands are increasingly drained and converted into commercial complexes, industries, stadiums and housing sites. Satellite images and information available with Survey of India indicate that nearly 2789 lakes have dried up and there are only 330 live lakes of medium to large range in Bangalore metropolitan region. Urban lakes and tanks all over the country as well as in the state of Karnataka are subjected to varying degrees of environmental degradation and pollution. The degradation is due to encroachments, eutrophication loads (from domestic and industrial effluents) and silt (KSPCB, 2001). The main causes for the deterioration of water quality in tanks are entry of pollutants due to discharge of untreated or partially treated wastewater from municipal sewage and domestic effluents and discharge of organic, inorganic and toxic pollutants of industrial effluents. These anthropogenic activities are the main sources of heavy metals contamination. Besides these, immersion of painted idols (containing different heavy metals) in the lake waters is also a potential source of heavy metal pollution.
