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 MICROPROPAGATION STUDIES ON CHRYSANTHEMUM (Dendranthema grandiflora Tzvelev.)(UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 1998) M, VISWANATH; T, MANJUNATH RAOAbstract not availableThesisItem Open Access STUDIES ON PERFORMANCE OF CHINA ASTER (CaUistephus chinensis Nees.) CULTIVARS(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-13) ANGADI, MANJUNATHA S.; Sathyanarayana Reddy, Dr. B.China aster is an half hardy annual commercial flower crop grown for its flowers. The flowers of aster are used for flower arrangement, interior decoration, garland making, worshipping. It can be grown in herbaceous borders, in flower beds, in garden decoration and also as potted plants. A field experiment was conducted at the Floriculture and Landscape Gardening department, Kittur Rani Channamma College of Horticulture, Arabhavi during the rabi season of 1999-2000 with ten China aster cultivars for evaluating their performance and to find out the promising cultivars for maximising the production of quality flowers. All the cultivars performed with wide and significant difference for growth and flowering characters and also for their response to the insect pest and diseases. The 'Phule Ganesh' series and the cultivar Violet Cushion' were vigorous in growth. Other 'IIHR' series and cultivar 'Ostrich Plume Mixed' were medium in growth, while the cultivar 'Giant Branching Comet' was dwarf in growth habit. The cultivars 'Giant Branching Comet' and 'Ostrich Plume Mixed' were early in flowering. The cultivar 'Phule Ganesh White' produced the largest flowers, longest stalk length, maximum flower yield and seed yield with extended vase life. The semidouble flower type are suitable for garland making. Cultivars 'Poornima', 'Phule Ganesh Purple' and 'Violet Cushion' produced more developed florets. The cultivars 'Violet Cushion' and 'Shashank' which are fully double are more suitable for cut flower production. Except the cultivars 'Poornima', 'Kamini' and 'Ostrich Plume Mixed', all other cultivars were moderately resistant to Helicoverpa pest and Altemaria leaf spot disease.ThesisItem Open Access INTEGRATED WEED MANAGEMENT IN CHINA ASTER (Callistephus chinensis Nees.), cv. Kamini(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-13) MURGOD, MAHANTESH I.; Sathyanarayana Reddy, Dr. B.A field experiment was carried out to study the effects of different weed control treatments in China aster (Callistephus chinensis Nees.) cv. Kamani, at the experimental field of Department of Floriculture and Landscape Gardening, Kittur Rani Channamma College of Horticulture, Arabhavi during 1999-2000. The experiment consisted of twenty treatments, consisting of two herbicides (pendimethalin and alachlor), hand weeding and wheat husk as mulch.These were considered alone or in various combinations and v;ere compared with unweeded control. The experiment was laid out in randomised block design (RBD) with three replications. Growth parameters, viz., plant height, number of leaves, number of branches and dry weight of plant were higher in weed free treatment throughout the crop period and in Integrated weed management treatments having either pendimethalin 1.50 kg a.e. ha'^ or alachlor 2.00 kg a.e. ha"^ along with wheat husk as mulch or manual weeding at 30 DAT. The highest yield of quality flowers were recorded in weed free treatment throughout the crop period and in integrated weed management treatments having either pendimethalin 1.50 kg a.e. ha ^ or alachlor 2.00 kg a.e. ha"^ along with wheat husk as mulch or manual weeding at 30 DAT. Weed control efficiency was high in weed free treatment throughout the crop period and with application of pendimethalin 1.5 kg a.e. ha"^ + wheat husk and alachlor 2.0 kg a.e. ha"^ + wheat husk. But application of pendimethalin 1.5 kg a.e. ha'^ and alachlor 1.00 and 2.00 kg a.e. ha"'' showed slight to moderate toxicity on China aster. Net retums and marginal returns were maximum in weed free treatment throughout the crop period. Among the treatments having herbicides, integrated weed management treatments having either pendimethalin 1.50 kg a.e. ha" or alachlor 2.00 kg a.e. ha"' along with wheat husk as mulch or manual weeding at 30 DAT resulted in the highest net and marginal retums.ThesisItem Open Access STUDIES ON THE EFFECT OF GA3 AND FOLIAR NUTRIENTS ALONG WITH BIOFERTILIZERS ON GROWTH FLOWERING AND VASE LIFE OF ANTHURIUM (Anthurium andreanum Lind.) Cv. TROPICAL RED(University of Agricultural Sciences, Bangalore, 2010-07-15) ANASUBAI, G. HANDARAGALL; JAYANTHI, R.The investigation on “Studies on the effect of foliar nutrients and GA3 along with bio-fertilizers on growth, flowering and vase life of Anthurium (Anthurium andreanum Lind.) cv. Tropical Red” was carried out during the year 2009 – 2010 at ZARS Division of Horticulture, Gandhi Krishi Vignana Kendra, University of Agricultural Sciences, Bengaluru. The experiment was conducted under 70% shade net with 11 treatments and 3 replications following Completely Randamized Design, with different combinations of GA3 (0ppm, 50ppm, 100ppm, 200ppm and 300ppm) and foliar nutrients (N at two levels, P at two levels and K at constant level) along with biofertilizers (Azospirillum, PSB and VAM at 2gm each per plant). Application of NPK at 30:10:10 at the rate of 0.2% spray, GA3 at 100 ppm along with application of biofertilizers (Azospirillum, PSB, VAM each at 2 g/ plant) recorded significantly maximum plant height (26.43 cm), maximum number of leaves (9.73) and leaf area (253 cm2), highest number of suckers per plant (3.50), early flower bud appearance and least number of days to flower opening (61.20 days and 12.00 days respectively), maximum number of flowers per plant and flower yield per m2 (4.46 and 34.00 respectively) and flower quality characters like spathe length and width (7.1 cm and 7.96 cm respectively) was significantly maximum with longest spadix (6.73 cm), highest spadix girth (1.22 cm), maximum stalk length (24 cm) and stalk girth (0.48 cm) and longest vase life (19.33 days) was observed in the same treatment combination. Of all the treatments, application of NPK at 30:10:10 at the rate of 0.2% spray, GA3 at 100 ppm along with application of biofertilizers (Azospirillum, PSB, VAM each at 2 g/ plant) proved to be the best in Anthurium andreanum Cv, “Tropical Red” for improving vegetative growth, flowering and vase life characters.ThesisItem Open Access EFFECT OF MICROBIAL MEDIA AMENDMENT AND FERTILIZERS ON GROWTH, YIELD AND QUALITY OF GERBERA UNDER POLYHOUSE(University of Agricultural Sciences, Bangalore, 2010-07-15) AKSHAYA RAMA, K.; JAYAPRASAD, K. V.The present investigation was carried out at the Department of Horticulture, G.K.V.K., U.A.S., Bengaluru, to study the effect of different levels of application of microbial media amendment on growth, yield and quality of Gerbera cut flower. The microbial media amendment (Mycoplex) was applied to the soil at the rate of 30 g/m2 and 50 g/m2 along with the recommended dose of fertilizers, at the intervals of 30 days and 60 days after planting. It was observed that plants grown in the treatment T3 (Mycoplex: 30 g/m2 of bed as basal dose + 75% recommended dose of fertilizers) showed highest growth in terms of maximum plant height, number of leaves per plant, leaf area and number of suckers per plant. The treatment T3 also proved to be useful in early flowering (reducing the number of days taken for flower bud initiation) and time taken for bud to bloom was also found to be reduced. During a period of 270 days, maximum number of flowers per plant, flowers per m2 and flowers per hectare ware recorded in T4 (Mycoplex: 50 g/m2 of bed as basal dose + 75% recommended dose of fertilizers), where as maximum stalk length, flower diameter and vase life were obtained in the treatment T3 (Mycoplex: 30 g/m2 of bed as basal dose + 75% recommended dose of fertilizers).ThesisItem Open Access IN VITRO MUTATION STUDIES IN Syngonium podophyllum(University of Agricultural Sciences GKVK, Bangalore, 2009-07-21) RAJESH, A. M.; SATHYANARAYANA, B. N.An efficient and reliable micropropagation protocol was developed and promising variants were obtained in Syngonium, an important foliage plant, by in vitro mutagenesis. Shoot proliferation from basal shoot explants were maximum (7.4) in MS media supplemented with 10mg/l of BAP. Length of shoots decreased with increased concentration of BAP. Except for plantlets derived from 20mg/l 0f BAP, all other plantlets showed 100 per cent establishment on the field condition. The shoots obtained with 20mg/l of BAP, failed to root. The mutagenic treatments of basal shoot explants of Syngonium, showed morphological variations. A general retardation in the shoot and root parameters of the regenerated plantlets was observed with ethyl methane sulphonate treatment. Greater variations were noticed in leaf morphology including reduction in size, length, curling of leaf. Few leaves turned albenic (reduction in chlorophyll) and this was more evident at higher level of EMS. Reduction in chlorophyll content and cultures turning albenic was observed when microshoots were treated with EMS. Lower concentration of EMS (0.5 per cent) did not induce variation in chlorophyll color, but with the increase in EMS concentration (1, 1.5 and 2 per cent) changes in chlorophyll color such as microshoots turning light green, albenic were seen. Stunted growth was observed when microshoots were treated with higher concentration of EMS. The encouraging results obtained from the present investigation thus emphasize the efficiency of in vitro mutation induction for the improvement of this important foliage plant.ThesisItem Open Access GENETIC AND TISSUE CULTURE STUDIES IN HELICONIA (Heliconia spp.)(University of Agricultural Sciences, Bangalore, 2010-07-15) PAVAN KUMAR, P.; JANAKIRAM, T.Heliconia is one of the emerging speciality cut flower crops having a great potential scope in both domestic and international market. Keeping this in view the present investigation was carried out on “Genetic and tissue culture studies in Heliconia (Heliconia spp.)”. Among 18 cultivars, Kawawuchi performed well for all vegetative parameters viz, plant height (302.50cm), leaf length (166.25 cm), leaf width (33.97 cm), leaves per sucker (6.30) and leaves per sq.m (159.82). Flowering parameters like maximum spike length (74.47 cm) and stalk length (79.95 cm) recorded in Guyana. Maximum bract length (27.60), number of bracts (17.65) and number of flowers per bract (16.10) recorded by Peddro Outiz, Pendent and Golden Torch respectively. The PCV and GCV were recorded high for spike length and number of bracts and narrow difference were recorded for all characters, indicating wide range of genetic variability and improvement of these characters through selection. High heritability coupled with high genetic advance as per cent over mean were observed for all characters except leaf width and leaves per sucker. Maximum percentage contribution for genetic divergence was by leaf length, followed by inflorescence length and number of bracts. Terminal buds are best explant source for in vitro multiplication of Heliconia psittacorum cv. Golden Torch with highest initiation of shoot bud growth (83%) with a survival rate of (28%) on MS medium supplemented with 5 mg/l BAP and 0.1 mg/l IAA. A combination of BAP 7 mg/l + IBA 0.5 mg/l found best for shoot tip establishment showing highest shoot length, multiple shoot induction and leaves/explant (48.37 mm, 1.12 and 3.12 respectively) in 45-50 days. Rooting of individual shoots was best achieved on MS medium containing IBA (2.5 mg/l) with the induction of higher number of roots (3.5 cm) and maximum root length (4.71cm).ThesisItem Open Access EFFECT OF SPACING AND FERTIGATION ON GROWTH AND YIELD OF BACHELOR’S BUTTON (Gomphrena globosa L.)(University of Agricultural Sciences GKVK, Bangalore, 2010-07-25) HEMALATHA, R.; Gopinath, G.The present investigations were carried-out to study the ‘Effects of spacing and fertigation on growth and yield of bachleor’s button’ (Gomphrena globosa) at the PFDC, Division of Horticulture, College of Agriculture, GKVK, UAS, Bangalore during 2009-10. The treatment T4 (30 cm x 30 cm + 120% RDF) produced high statured plants (69.17 cm) and more number of branches per plant (12.00). The treatments T4 and T6 (on par) registered higher girth of stem. The treatment T4 & T6 (45 cm x 30 cm + 100% RDF) (on par) recorded maximum spread of plant (43.83 and 42.83 sq.cm). The treatments T4, T5 and Tg (on par) resulted in maximum fresh weight (117.76, 102.74 and 108.64 g) and dry weight of shoot (79.11, 68.85 and 72.98 g). Maximum fresh weight (14.13 g) and dry weight of root (9.05 g) were recorded in the treatment T4. The treatment T4 registered maximum fresh weight (77.10 g) and diy weight of hundred flowers (40.54 g). The treatment T4 resulted in maximum weight of flowers per plant (117.68 g), per square metre (1295.42 g) and per hectare (12.9 t), and also produced maximum number of flowers per plant (193.10), per square metre (2176.67) and per hectare (21.76 lakhs). The treatments T4 and T6 (on par) took minimum time for drying under shade (8 and 9 days), sun (4 and 5 days) and oven methods (8 and 9 hours), while the treatment T4 took minimum time for drying under micro oven drying (2 min). The treatments T7 and Ti (on par) recorded minimum colour change of flowers under oven (3.2 and 3.4) and micro oven drying (3.4 and 4.0). The treatment T4 experienced better keeping quality under shade (5.0), sun (3.0), oven (4.6) and micro oven drying (4.8). For growth and yield parameters of Gomphrena globosa, closer spacing of 30 cm x 30 cm and fertigation @ 120 % of the recommended dosage of fertilizers was found to be better as revealed by the net returns (Rs 1, 88,057/ha) and the cost benefit ratio (1:2:65)ThesisItem Open Access Effect of floral preservatives on the post harvest life of gerbera (Gerberajamesonii, Hook) cv.
