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 EFFECT OF PACKAGING MATERIALS AND ZEOLITE ON SEED LONGEVITY OF ONION SEEDS (Allium cepa L.)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-01) AKSHATHA., K. S; NARAYANASWAMY, S.A laboratory experiment was conducted to study the effect of packaging materials and zeolite on seed longevity of onion seeds (Allium cepa L.) at Department of Seed Science and Technology, UAS, GKVK, Bengaluru during 2016-17. The study comprised of four packaging materials viz., cloth bag, aluminium foil, vacuum polythene bag and super grain bag and two types of zeolite viz., zeolite powder and zeolite beads stored for 10 months with FCRD in three replications. The results revealed that among the packaging materials, the seeds stored in aluminium foil recorded highest seed quality attributes viz., germination (70.49 %), seedling length (11.21 cm), seedling dry weight (1.91 mg), seedling vigour index I (792), speed of germination (0.806), dehydrogenase activity (1.124 A480nm), amylase activity (72.4 μg/g), moisture content (8.52 %), electrical conductivity (727 μS/ppm) and total soluble sugars (125.63 μg/ml) at the end of ten months of storage. Among the zeolite types, seeds dried to 5 per cent moisture content using zeolite beads resulted in higher seed quality parameters viz., germination (68.97 %), seedling length (10.64 cm), mean seedling dry weight (1.88 mg), seedling vigour index I (739), speed of germination (0.806), dehydrogenase activity (1.115 A480nm), amylase activity (74.8 μg/g), moisture content (8.90 %), electrical conductivity (743 μS/ppm), and total soluble sugars (124.45 μg/ml) was observed at the end of ten months of storage. The study can be concluded that the onion seeds dried to 5 per cent moisture content using zeolite beads and stored in aluminium foil could be stored for ten months satisfactorily.ThesisItem Open Access STUDIES ON INTEGRATED APPROACH FOR ENHANCING PLANT GROWTH, SEED YIELD AND QUALITY IN FINGER MILLET (Eleusine coracana L. Gaertn)(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2016-09-10) CHINTHALAPATI, SRAVANI; Narayanawamy, SFinger millet is an important minor millet crop mostly cultivated owing to its calcium, iron and fibre content. In recent years selective utilization of crops, varieties and chemical fertilizers have threatened agro-biodiversity leading to rapid erosion of natural resources and consequently affecting the nutritional security of people. Considering impact of this, a field experiment was carried out to study the "Influence of integrated approach on enhancing plant growth, seed yield and quality parameters in finger millet" at J-Block, NSP, GKVK, UAS, Bengaluru during kharif 2015. The treatment combinations were arranged in split split plot design with two replications which includes different methods of sowing in main plot viz., (S1-direct sowing and S2-transplanting and four nutrient managements) in subplots (N0-without fertilizer, N 1-organic fertilizers, Nichemical fertilizers, N3-integrated) and subsubplots consists of priming treatments (Powithout priming, P1-hydropriming, P2-chemopriming and P3-biopriming). The results revealed that, S2 transplanting method of sowing, N3 integrated application of RDF- 100:50:50 NPK kg ha-1 in the form of neem + verrnicompost +urea+ SSP + MOP and P2 chemopriming with (2 % ) KH2P04 for 6 hours recorded highest growth, seed yield and quality attributes viz., field emergence (93.00 %), chlorophyll content (1.924 mg g-1 FW), number of tillers (14), ear head weight per plot (9.53 kg), germination (95.00 %), mean seedling length (18.45 cm), less number of fresh ungerminated seeds (5) and seed yield of (36. 78 q/ha ) when compared to ( control) direct sown without any nutrient and priming (14.68 q/ha).ThesisItem Open Access LAND RESOURCE ASSESSMENT OF NAGENAHALLI WATERSHED, DODDABALLAPUR TALUK, BANGALORE RURAL DISTRICT USING REMOTE SENSING AND GIS TECHNIQUES.(University of Agricultural Sciences, Bangalore, 2010-08-15) NALINA, C. N.; Anil Kumar, K. S.Comprehensive land resources information is important for efficient land use planning and fertilizer being the costliest input, the use of plant nutrients has to be need based. Hence a detailed characterization of land resources were undertaken in Nagenahalli watershed, located between 13º 22′ 20.2″ to 13º 22′ 58″ N latitude and 77º 32′ 52.4″ to 77º 33′ 27.7″ E longitude and an elevation between 911 to 930 m above MSL covering 225.2 ha in Doddaballapur taluk, Bangalore Rural District. Climate of the area is semiarid tropical with a mean annual rainfall of 826.1 mm and temperature of 23.8 °C. Cadestral map, satellite imagery and Google Earth images were used in conjunction with SOI toposheets to map the land use, study physiography-soil relationships and to prepare the soil map. The information gathered has been processed under GIS environment to generate thematic maps on crop suitability and fertility capability. Soils are developed from granite and its colluvium. Horizon-wise soil morphological, physical and chemical properties of major soils were studied. Composite plot-wise surface soil samples were analysed for fertility. Five soil series have been identified and mapped into 15 soil mapping units. All the soil series identified are Nagenahalli- a (Na-Typic Kandiustalf), Nagenahalli-b (Nb-Typic Kandiustalf), Nagenahalli-c (Nc- Kanhaplic Haplustalfs), Nagenahalli-d (Nd-Ultic Paleustalfs) and Nagenahalli-e (Ne- Kandic Paleustalfs) are very deep except Nc, which is moderately shallow. The soils of Na and Nb are red with low CEC and low base saturation and having kandic horizon and soils of Na- series have gravel layer below 50 cm. Nc series covers largest area of 87.8 ha followed by Nd series, covering an area of 50.8 ha. The soils of Nc series are fine-loamy and are non-gravelly with very less clay content, while the soils of Nd and Ne series are fine, red and very gravelly. Gravel layer starts below 40 cm and have medium CEC. Major surface soils of the study area are non-gravelly and sandy clay loam (99 ha) textured and are poor in organic carbon (0.3 to 0.4 %) moderately or strongly acidic (176 ha) and low in available N (174 ha) and K (157 ha) but rich in P (170 ha) and sufficient (176 ha) in Zn. Major soils are suited to maize, ragi, and vegetables. Eucalyptus plantations on sloppy eroded lands (62.8 ha) can be retained but not on prime lands.ThesisItem Open Access STANDARDIZATION OF SEED PRODUCTION TECHNOLOGY FOR PIGEONPEA cv. BRG-2(University of Agricultural Sciences, Bangalore, 2009-07-15) VISHNUVARDHAN; RAJENDRA PRASAD), S.The field investigation was carried out during kharif 2008 at the AICRP on seed technology, Gandhi Krishi Vignana Kendra, University of Agricultural Sciences, Bangalore in randomized complete block design with three replications and three factors viz., Spacing of 90 x 20 cm, 120 x 20 cm and 150 x 20 cm, with and without micronutrients and plant protections Profenofos + Spinosad + Malathion, Profenofos + Spinosad + Spinosad (+ Malathion and Biopesticides (NPV Spray followed by NSKE spray) with 18 treatment combinations and also investigated for morphometric characterization of pigeonpea cv. BRG-2. The results indicated that Sowing of pigeonpea cv. BRG-2 is resulted in more number of primary (37.22) and secondary (39.75) branches per plant, Pods per plant (257.6), with good quality seeds in terms of maximum germination (89 %), mean seedling length (32.2 cm) and vigour index I & II (2725 & 2074, respectively) at a spacing of 150 x 20 cm and lowest was at 90 x 20 cm irrespective of the treatments but plant height at harvest (206.9) and seed yield (16.25 q ha-1) was maximum at lower spacing of 90 X20 cm. Similarly plant height at harvest (203.9), number of primary (35.4) and secondary (37.65) branches per plant, pods per plant (239.7) and seed yield (14.56 q ha-1) are higher at micronutrients applications along with good quality seeds in terms of maximum germination (90 %), mean seedling length (30.93 cm) and vigour index I & II (2764 & 1932, respectively) over without micronutrients. Plant protection measures are not having significant differences but it has significant effect on seed yield, higher seed yield (15.23 q/ha) was at four sprays of insecticides. Concluded that for seed production of pigeonpea cv. BRG-2, spacing of 90 x 20 cm with application of micronutrients and timely applications of four plant protection measures could be adopted to get higher seed yield (16.82 q/ha) with quality seeds under Bangalore condition.
