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.

S.Studies on four medicinal plant species viz., Ammi majus, Phyllanthus emblica, Plantago ovata and Psorelia corylifolia was undertaken to standardize media and temperature required to test for germination in the laboratory. The experiment was comprised of nine temperature ranges involving four constant(20", 25", 30°, 35° C) and four alternate (20-30°, 25-35°, 20-35°, 15-25° C) temperatures along with one ambient temperature. The three media were Between Paper (BP), Top of Paper (TP) and Sand (S). Among the different temperatures and media studied, the maximum germination (95.50%) was observed in Ammi majus at 20-0 temperature in BP method. The first and final count were fixed on 6th and 10th day, respectively. In sand medium at alternate temperature of 20-30°C Phyllanthus amblica recorded maximum germination (95.00%). This was found on par with 25-35=0 temperature. The first and final count can be fixed on 5th and 10th day, respectively. The alternate temperature of 15-25=0 in BP method recorded highest germination (96.00%) in Plantago ovata. The first and final count can be fixed on 2nd and 5th day, respectively in BP method. In Psorelia corylifolia highest germination (95.00%) was observed in sand medium at 15-25=0. The first and final count can be fixed on 2nd and 5th day, respectively.ThesisItem Open Access INFLUENCE OF STAGES OF HARVESTING ON SEED YIELD, QUALITY AND INCIDENCE OF Aspergillus flavus IN CONFECTIONERY GROUNDNUT VARIETIES(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-03) TIMMANNAVAR, MANOHAR; UMAPATHY, P. N.In an attempt to findout the influence of stages of harvesting on seed yield, quality and incidence oi Aspergillus flavus in confectionery groundnut varieties, a field experiment was conducted during kharif 1998 at College of Agriculture Farm, University of Agricultural Sciences, Dharwad. The experiment consisted of 18 treatment combinations comprising six varieties (TKG-19A, ICGV 86564, BAU-13, Somanath, JL-24 & Dh-3-30) and three harvesting stages viz., one week early, normal and one week late stage in randomized block design with factorial concept. The results indicated that in yield and its attributing characters, JL-24 recorded higher number of pods per plant, pod and seed yield per plant, pod and seed yield per hectare Among the harvesting stages, the normal harvesting stage resulted in higher values in these parameters followed by later and early harvesting stages. The seed quality parameters like sound mature kernels, shelling percentage, vigour index, field emergence, germination percentage, shoot and root length and oil content were highest in JL-24 with minimum electrical conductivity, moisture content and less incidence of Aspergillus flavus. The variety BAU-13 resulted in higher incidence oi Aspergillus flavus, electrical conductivity and moisture content. Whereas, ICGV 86564 recorded highest 100 seed weight. Among the harvesting stages, the normal stage recorded higher values with lesser incidence of Aspergillus flavus and electrical conductivity followed by late and early harvesting stages. The variety BAU-13 recorded highest per cent recovery of bold seeds with less recovery of medium and small seeds. The recovery of bold and medium seeds was higher with lower recovery of small seeds in normal harvesting stage. Among the confectionery varieties ICGV 86564 was found to be superior for various quality parameters ultimately resulting in higher returns of Rs.43,353/ha. Hence, it is concluded that this variety can be grown under Dharwad condition for confectionery purpose.ThesisItem Open Access SEED TECHNOLOGICAL INVESTIGATIONS IN NATURALLY COLOURED COTTON GENOTYPE, DDCC-1(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-03) RADHAKRISHNA, MAIYA M.; GOWDA, BASAVEThesisItem Open Access EFFECT OF DATES OF SOWING AND CHEMICALS ON SEED YIELD AND QUALITY OF MALE PARENT SB (YF)-425 COTTON (Gossypium barbadense L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-04) ULLAGADDI, M. S.; Umapathy, P. N.A field experiment was conducted at Main Research Station, University of Agricultural Sciences, Dharwad during kharif 1999-2000 to find out the effect of dates of sowing and chemicals on seed yield and quality of barbadense cotton cultivar SB(YF)-425. The experiment consists of two dates of sowing (main plots) and nine treatments (sub plots) comprising of two plant growth regulators and two micronutrients at different concentrations and different combinations. The experiment was laid out in split plot design with three replications. The data indicate that the May sowing was found to be best to produce higher yields and high quality seeds as compared to June sowing. Plant height and number of leaves increased significantly due to foliar application of ZnS04 (0.1%) and boron (0.1%) in combination with GA3 (50 ppm). The application of growth regulators and nutrients significantly increased the number of squares, flowers and matured bolls per plant except acetyl salicylic acid which resulted in significantly higher values for these parameters. The yield and yield components were significantly influenced due to growth regulators and nutrients. Among the treatments, the highest yield and yield components were recorded in RDF + foliar spray of ZnS04 (0.1%) + Boron (0.1%) in combination with GA.i (50 ppm) followed by ZnS04 (10 kg/ha) + Boron (5 kg/ha) + GA,3 (50 ppm). The seed quality parameters were significantly improved by the use of growth regulators and nutrients. Significantly higher germination, shoot length, root length and vigour index were observed in plants sprayed with ZnS04 (0.1%) + Boron (0.1%) + GA3 (50 ppm).ThesisItem Open Access INFLUENCE OF POTASSIUM NUTRITION AND STAGES OF HARVESTING ON SEED YIELD AND QUALITY OF RABI SORGHUM VARIETIES(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-04) SAJJAN, M.M.; SHEKHARGOUDA, M.ThesisItem Open Access EFFECT OF SEED INVIGOURATION ON STORABILITY AND FIELD PERFORMANCE OF SOYBEAN (Glydne max (L.)

B.ThesisItem Open Access EFFECT OF MOTHER PLANT NUTRITION, PLANT DENSITY AND SEED MATURITY ON SEED YIELD AND QUALITY IN MARIGOLD (Tagetes erecta L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-04) SHIVAKUMAR, C. M.; BASAVEGOWDA, Dr.Studies were conducted to know the effect of fertilizer, spacing and physiological maturity of seed on seed yield and quality in marigold at Agricultural collage farm, university of Agricultural Science, Dharwad during Kharif 1999. The treatments included are three levels of fertilizes (F1-225:60:60, F2=270:72:72, and F3=315:84:84 NPK kg/ha) and five plants spacings (S1=30*30, S2=45*30, S3=45*45,S4=60*30, and S5=60*45 cm) and experiment was laid out in split plot design with three replications. For the purpose of knowing physiological maturity of seeds heads (capitula) were harvested at seven stages from 13 to 43 days after flower opening (DAF) with an interval of five days. The results indicated that significantly higher yield of good quality seed (579.7 kg/ha) was noticed with the application of 270:72:72 kg NPK per hectare with 60x30 cm spacing (55555 plants/ha) and also it recorded the highest net returns per hectare (Rs.l,17,863). Further increase in fertilizer level to 315:84:84 kg per hectare at the same spacing level did not cause any appreciable effect on seed yield and quality.Among the seven stages of harvesting, seeds harvested at 28 days after fiower opening recorded maximum 1000 seed weight (3.19 gt germination (83%), seedling length (11.92 cm) and vigour index (988) as' compared to the seeds obtained from either delayed or early harvested heads.Based on the results it could be concluded that fertilizer level of 270.72:72 kg per hectare with the spacing of 60x30 cm appeared to be the optimum levels for quality seed production of marigold and the seed crop should be harvested at 28 days after flower opening.
