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 Embargo MORPHO-MOLECULAR CHARACTERIZATION OF SELECTED LAND RACES OF RICE (Oryza sativa L.)(University of Agricultural Sciences, Bangalore, 2023-03-29) Deepika, C.; P. J. DevarajuIn the present investigation, 31 land races were characterized for 64 morphological, physiological and molecular traits. The experiment was conducted in RCBD with three replications at OFRC, UAHS, Shivamogga during kharif 2021. Out of sixty four traits studied, significant variations were observed for all qualitative and quantitative characteristics. Out of 31 land races, Ambemohari showed maximum number of productive tillers/plant (26), Jasmine obtained highest panicle length (27.90cm), Karigajavale showed maximum panicle weight (5.30 g), Rathnasagara recorded the highest number of seeds per panicle (218) and seed yield per plant (85.80 g). Seedling and plant characters are major identification and differentiating characters among cultivar. Out of 25 markers, the highest Polymorphic Information Content (PIC) value (0.49) was obtained in RM 481 and RM 25, remaining markers showed less PIC value. It was observed that the highest PIC value results were genetically diverse land races and some markers showed related land races. In respect of seed dormancy, three (Navara, Jyothi and Misebhatta) land races showed very weak, one (Raichursanna) land race weak, one (Puttabhatta) land race moderate, five (Gowrisanna, Kiruvani, Rathnasagara, Ambemohari and MTU-1001) land races strong and twenty one land races as very strong dormancy reaction signifying considerable amount of variability among the land races. Seed dormancy positively correlated with seed length, presence of awns and germination percentage.ThesisItem Embargo AN ANALYSIS OF KNOWLEDGE LEVEL, TECHNOLOGICAL AND YIELD GAP OF POMEGRANATE PRODUCTION IN TUMKUR DISTRICT OF KARNATAKA(2022-12-27) GOWTHAMI. V.; VINAY KUMAR. RThe present investigation was conducted to assess the knowledge level, technological and yield gap by 120 randomly selected pomegranate growers from Sira and Pavagada taluks of Tumkur district. Results revealed that 38.83 per cent of Sira pomegranate growers and 48.33 per cent of Pavagada pomegranate growers belonged to medium knowledge level. Further, 35.00 per cent and 40.83 per cent of Sira and Pavagada pomegranate growers had medium technological gap, respectively. In Sira and Pavagada taluks 33.33 per cent and 43.33 per cent of pomegranate growers belonged to medium and high yield gap category, respectively. Pooled data indicated that 43.33 per cent, 40.83 per cent and 36.67 per cent of pomegranate growers had medium knowledge level, medium technological gap and medium yield gap, respectively. The data subjected to ‘Z’ test indicated that there was a significant difference in the yield gap of Sira and Pavagada farmers. Knowledge level, Technological and Yield gap were non-significantly associated with age, family size and significantly associated with education, farming experience, achievement motivation, risk orientation, innovative proneness, scientific orientation, management orientation, cosmopoliteness, economic motivation and social participation at five per cent level of significance, while annual income, land holding, area under pomegranate, extension contact, extension participation at one per cent level of significance. Major constraints expressed by pomegranate growers were poor knowledge in pest and disease management, lack of availability of quality seedlings, lack of knowledge on postharvest practices and lack of storage facilities.ThesisItem Embargo STUDIES ON SEED TESTING PROTOCOL AND SEED LONGEVITY IN CHIA (Salvia hispanica L.)(2023-01-12) UDAY, K. V.; S. N. VASUDEVANA laboratory experiment was conducted at AICRP on Seed (Crops), UAS, GKVK, Bengaluru during 2021-22. Chia seeds were subjected to germination at different temperatures (20, 25 and 30 ℃) and substrates (sand, between paper and top of paper). Among the temperatures, higher germination (75.58 %), mean seedling length (14.23 cm) and seedling vigour index-I (1076) were recorded at 25 ℃. Among the substrates, higher germination (70.51%), mean seedling length (12.47cm) and seedling vigour index-I (891) were recorded in top of paper method. To study the seed storability, chia seeds were treated with four different chemicals (untreated, sweet flag @ 2g/kg, carbendazim @ 1g/kg and captan @ 2g/kg) and packed in three different packaging materials [cloth bag, super grain bag and polythene bag (700-gauge)]. Among the packaging materials, seeds stored in polythene bag (700-gauge) recorded better seed quality attributes viz., germination (66.34 %), mean seedling length (9.51 cm), seedling vigour index-I (635) and total dehydrogenase activity (1.089 A480 nm) up to ten months of storge. Among the chemicals, seeds treated with carbendazim @ 1g/kg resulted in higher seed quality parameters viz., germination (65.50 %), mean seedling length (9.66 cm), seedling vigour index-I (640) and total dehydrogenase activity (1.030 A480 nm). It is concluded that, temperature of 25 ℃ and top of paper method seems to be ideal for testing seed germination of chia and seeds could be stored up to ten months under ambient condition by treating with carbendazim and packed in polythene bag (700-gauge).ThesisItem Embargo STUDIES ON THE EFFECT OF SOWING WINDOWS ON SEED YIELD AND QUALITY OF CHIA (Salvia hispanica L.)(2023-01-12) PRASANKUMAR, B. GURUVANNAVAR; S. N. VASUDEVANExperiment was conducted to study the effect of sowing windows on seed yield and quality of chia at Zonal Agricultural Research Station, V. C. Farm, Mandya, during Kharif season 2021. The experiment consisted of six treatments with different sowing dates viz., 13th June-(T1), 28th June-(T2), 12th July-(T3), 26th July-(T4), 12th August-(T5) and 28th August-(T6) in Randomized Block Design with four replications. Results revealed that, growth and yield parameters in terms of plant height, number of leaves, number of spikes and seed yield ha-1 were significantly higher in 12th August sowing (93.70cm, 41.90, 14.75 and 841.87kg, respectively) followed by 26th July sowing. Further, to standardize suitable screen aperture size for processing of chia seeds, experiment was carried out using two types of bottom screens (Slotted-S and Round-R) with different size viz., S(0.8mm), S(0.9mm), S(1.0mm), R(1.1mm), R(1.3mm) and R(1.5mm) with four replications in Completely Randomized Design. The screen aperture size S(0.8mm) recorded maximum seed recovery (98.25%), physical purity (96.46%), germination (73.33%), real value of seed (70.74%), seedling length (13.13cm), seedling vigour index-I (962) followed by R(1.1mm) with seed recovery (96.87%), physical purity (96.77%), germination (72.33%), real value of seed (70.01%), seedling length (12.81cm), seedling vigour index-I (926). It is concluded that, sowing of chia crop either during last week of July or first fortnight of August is ideal for quality seed production and processing of chia seeds can be done either by using slotted 0.8mm or round 1.1mm screen aperture size for better seed recovery with good seed quality parameters.ThesisItem Embargo SYNTHESIS AND CHARACTERIZATION OF ZINC AND SILICA GREEN NANOPARTICLES AND THEIR EFFICACY AS A STORED SEED PROTECTOR AGAINST BRUCHID IN PIGEONPEA [Cajanus cajan (L.) Millsp.](2023-01-19) SAMPATHI SOWJANYA; Dr. S. RAJENDRA PRASADA study was undertaken to assess the effect of seed treatment with green zinc oxide (ZnO) and silicon dioxide (SiO2)nanoparticles (NPs) for improving seed quality and storability in pigeonpea. Green ZnO (synthesized using spinach leaf) and chemical ZnO NPs were characterized and confirmed the nano range with average diameter of 28.54 nm and 15.92 nm respectively with spherical shape and elemental composition of zinc and oxide. Green SiO2 (synthesized using rice husk) and chemical SiO2 NPs were characterized and confirmed the nano range with average diameter of 24.50 nm and 20.15 nm respectively with spongy nature with spherical shape and confirmed elemental composition of silicon and oxide. Among concentrations, green ZnO @ 1250 & 1000 ppm, chemical ZnO @ 500 ppm, green SiO2 @ 500 & 750 ppm and chemical SiO2 @ 250 ppm were found better for seed quality and insect control of pigeonpea during storage. At initial and end of the seed storage, green ZnO NPs @ 1250 ppm recorded significantly highest seed quality parameters like higher germination (96.25 & 80.25 %), field emergence (94.50 & 77.25 %) and highest protein content, CAT, SOD (22.62 & 21.49 %, 81.340 & 81.32 μg g-1 protein & 654.366 & 599.215 min-1 g-1 protein respectively). For insect control, green SiO2 @1000 ppm recorded the lowest number of eggs per 100 seeds (2.33 & nil respectively) and adult emergence (3.3% & nill respectively). SSR primers produced only monomorphic banding pattern in both nanoparticles treated seeds and control seeds. Under pot culture, green ZnO @ 1250 ppm recorded maximum number of nodules per plant (99.75), seed yield per plant (53.73g), 100 seed weight (14.71g), seed germination (94.0%) and SVI-II (4795). This study revealed that, green nanoparticles seed treatment maintains the seed quality in pigeonpea during storage.ThesisItem Open Access INFLUENCE OF SEEDLING SOURCE AND METHOD OF PLANTING ON CROP GROWTH, SEED YIELD AND QUALITY IN FINGER MILLET (Eleusine coracana L. Gaertn)(University of Agricultural Sciences, Bangalore, 2020-12-06) KAVYASHREE, K R; SIDDARAJU, RA field experiment was conducted at NSP, UAS, GKVK, Bengaluru during kharif 2019 to study the influence of seedling source and method of planting on crop growth, seed yield and quality in finger millet. Experiment consisted of 12 treatment combinations comprising of two seedling sources and six levels of planting geometry laid out in factorial RCBD design with three replications. Among different treatment combinations, protray seedlings transplanted at 30 x 10 cm recorded maximum plant height at 60 DAP and at harvest (100.33 and 103.80 cm, respectively) and guni method of planting at 90 x 90 cm recorded maximum number of tillers hill-1 (24.20), number of ear heads hill-1 (35.53) and ear head weight plant-1 (167.93 g). Seed yield parameters viz., seed yield plant-1(90.67g) was recorded highest in guni method of planting at 60 x 60 cm with nursery bed seedlings, whereas protray transplanted seedlings at 30 x 10 cm recorded maximum seed yield plot-1 (8.76 kg) and seed yield hectare-1 (45.14 q). Seed quality parameters was recorded maximum in guni method of planting at 60 x 60 cm with nursery bed seedlings like seed germination, SVI-I and SVI-II (96.67%, 1299 and 206, respectively). Higher net returns (Rs.1,18,564) and B:C ratio (4.38) was recorded under protray seedlings transplanted at 30 x 10 cm owing to its higher seed yield and straw yield when compared to other treatments.ThesisItem Embargo STUDIES ON THE INFLUENCE OF PROVENANCE ON SYNCHRONIZATION OF FLOWERING, SEED SETTING, SEED YIELD AND QUALITY OF SUNFLOWER HYBRID KBSH -78 (Helianthus annuus L.)(2022-12-02) HARSHITHA, S. R.; RAMANAPPA, T. M.The present investigation was carried out to obtain information on the response of parental lines to the environment in different provenances with respect to flowering behaviour of male and female parents and their synchronization, seed yield and quality parameters in newly released sunflower hybrid KBSH-78 (CMS 1103A x RHA92) during rabi (crop sown in the month of December 2021). The study indicated that sowing of parental lines at different locations had no significant effect either on growth, seed yield and quality parameters. However, the seed crop of Bagepalli recorded higher values for plant height (105.60 cm), days to 50 per cent flowering (62.55), days to maturity (97.84), seed yield / plant (18.93 g), 100 seed weight (4.40 g), seed yield /ha (1051.66 kg), germination (90.50 %). The staggered sowing was found to be non-significant for all growth, yield and quality parameters in both male and female parents, but sowing of male parent by four days late to female parent (S3) resulted in better synchronized flowering between male and female parents which lead to enhanced seed set (84.58%). In female parent, sulphur spray recorded higher values for capitulum diameter (13.18 cm), seed yield per plant (22.55 g), number of filled seeds (311.01), 100 seed weight (6.88 g), seed setting (84.58%), seed yield (1252.92 kg/ha) and quality parameters like germination (91.78 %), shoot length (18.25 cm), root length (20.68 cm), seedling dry weight (0.37 g), mean seedling length (38.16 cm), SV-I (3503) and SV-II (34). The germination was maximum (99.70%) at 50 DAH in Ranebennur followed by Bagepalli (99.60%) and Bengaluru (99.25%) although no germination was recorded in freshly harvested seeds.ThesisItem Embargo STUDIES ON SEED INVIGOURATION FOR ENHANCING PRE-SOWING QUALITIES AND SEEDLING TRAITS IN SWEET PEPPER (Capsicum annuum L.)(2022-12-12) LAXMI DUNDAPPA CHOUGALA; PARASHIVAMURTHYAn experiment was carried out to enhance the pre-sowing qualities and seedling traits of sweet pepper during 2021/22 at the Department of Seed Science and Technology, UAS, Bangalore. Initially, standardization was done for different temperature and soaking duration for invigouration treatment. Among treatment, seeds soaked for 16 hours at 30°C enhance the seedling quality viz., seed germination (93.0 %), mean seedling length (8.47 cm) and seedling vigour index – II (462). Further, the effect of different invigouration methods like halopriming, osmo priming, biopriming and nano priming were conducted. Among them, seed primed with KNO3 at 2 %, polyethylene glycol (PEG 8000) at -1.5 MPa, compost tea at 30 %, ZnO at 250 ppm with water soaking and ZnO at 250 ppm with polymer coating recorded the highest seed germination (87.0, 85.0, 84.0, 87.0 and 82.0 %), mean seedling length (9.84, 9.20, 8.65, 12.45 and 11.41 cm) and seedling vigour index – II (410, 377, 338, 420 and 348) respectively. Later, best treatments were selected to assess the seedling performance under portray method. Seed primed with KNO3 at 2 % showed highest seedling emergence (90.0 %) at 15 DAS and seedling recovery (91.0 %) at 30 DAS. Further, these treatments were also assessed for relative storability of invigourated seed through artificial ageing. Seeds primed with compost tea at 30 % recorded higher seed quality attributes like radicle emergence (40.0 %), seed germination (40.0 %), mean seedling length (9.73 cm) and seedling vigour index – II (165) even after three days ageing.ThesisItem Embargo RESPONSE OF TRADITIONAL RICE (Oryza sativa L.) VARIETIES FOR GROWTH, SEED YIELD AND QUALITY TO DIFFERENT SOURCES OF NUTRITION(University of Agricultural Sciences, Bangalore, 2022-12-13) MEGHANA, V; SIDDARAJU, RThe field experiment was conducted during Kharif, 2021 at AICRP on Seed (Crops), UAS, GKVK, Bengaluru, to study the response of traditional rice (Oryza sativa L.) varieties for growth, seed yield and quality to different sources of nutrition. The experiment consists of twelve treatment combinations involving four varieties and three levels of nutrition sources laid out in factorial RCBD design with four replications. Results revealed that significant differences were noticed between the treatments for crop growth, yield and quality parameters. Among different treatment combinations, variety Gandhari grown with the RDF (Urea-217 kg, SSP-312.5 kg, MOP-83 kg/ha) recorded maximum plant height at 60 DAS (91.65 cm), at harvest (94.83 cm), number of tillers per hill (10.72), panicle length (18.20 cm), number of seeds per panicle (121.20) and seed yield (57.80 q/ha), which is followed by application of organics (10 tonnes FYM + 2500 kg Vermicompost + 10 kg PSB + 10 kg KSB per ha). Among the quality attributes seed recovery (80.10 %) was maximum by application of RDF while, the other quality attributes like germination (92.80 %), mean seedling length (21.50 cm), seedling dry weight (10.94 mg), SV-І (1898), SV-Ⅱ (1014) and carbohydrate content (67.75 %) were highest in Gandhari grown with organics. Among interactions V2N2 (Gandhari + RDF) registered the highest BC ratio (3.82:1) whereas, lowest (1.28:1) was obtained in V1N1 (Gandhari + No fertilizers). It is concluded that RDF treatment showed positive influence on crop growth, yield whereas organics have positive effect on quality of rice
