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.

    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, Parama
    Lakes 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.

    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-10) VITTHAL, CHABBI; CHANNAKESHAVA, B. C.
    Field and laboratory experiments were conducted at G.K.V.K, Bengaluru during kharif-2014 to study the effect of seed fortification and temperature tolerance in finger millet varieties. Twelve popular varieties of finger millet were screened for thermo tolerance and susceptibility by employing Temperature Induction Response (TIR) technique. The varieties PES-110 and KJNS-52 fortified with seed fortification treatments in field experiment. The crop was sown at 30 x 10 cm spacing and replicated thrice in a Factorial Randomized Complete Block Design. The observations on growth, seed yield and quality were recorded. Variety PES-110 possessing higher seedling survival (91.66 %) with lesser reduction in recovery growth of root and shoot (43.15_% and 38.17_%) and was identified as temperature tolerant compare to thermo-sensitive variety KJNS-52 with less per cent seedling survival (50_%). Laboratory studies revealed that seed fortification with 100 ppm CaCl2 subjected to high temperature (53° C for 2hr) recorded highest seed quality attributes viz., germination (43.46_%), total seedling length (11.62_cm), SVI-I (546) and II (58). In field experiment study seed fortification with 1_% KH2PO4 recorded higher growth and yield parameters viz., plant height (105.28_cm), lesser days to 50_% flowering (70.50), ear head weight (26.98_g/plant), seed yield (2941.84_Kg/ha) and higher seed quality attributes viz., germination (93_%), mean seedling length (15.64_cm), seedling dry weight (1.24_mg), SVI-I_&_II (1116 & 115, respectively). Meanwhile, PES-110 fortified with 1_% KH2PO4 recorded 33_% increased seed yield/ha over KJNS-52 control. Under high temperature stress (53° C) the variety PES-110 with 100 ppm CaCl2 recorded higher thermo tolerance compare to other treatments.

    VARIETAL CHARACTERIZATION AND ABIOTIC STRESS STUDIES ON SEED QUALITY OF BRINJAL (Solanum melongena L.) VARIETIES
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-10) RAJATHA, K. D.; CHANNAKESHAVA, B.C
    Brinjal is one of the most important vegetable crop in India. Present investigation was undertaken to characterize 12 brinjal genotypes based on the morphological traits and to study the effect of drought and high temperature stress on seed quality parameters. Drought and high temperature stress were imposed on four brinjal genotypes to study the seed quality parameters by using three concentrations of PEG 6000 (0, -1 MPa and -1.5 MPa) and subjecting seeds to three different temperature (25 °C, 35 °C and 40 °C). Characterization studies revealed wide variation among genotypes for most of the parameters studied viz., seed size, anthocyanine pigmentation, vein colour, fruit shape, flower size and flower colour. Brinjal green round was the sole genotype which exhibited small sized flowers, whereas Arka Shirish and Arka Kusumakar showed greenish white colour flower. The experimental results revealed that drought stress and high temperature resulted in decreased seed germination, mean seedling length, seedling vigour index, total dehydrogenase activity and increased electrical conductivity. Drought stress (-1.5 MPa) reduced the germination per cent by (9 %) when compared to control (90 %). Similarly in high temperature stress (40 °C) the germination per cent in all the genotypes is zero, whereas in control recorded 88.5 %. As the stress increases there was significant increase in the activity of peroxidase (POD) and esterase (EST) under both high temperature and drought stress, irrespective of genotypes. However among the four genotypes studied in the experiment, Arka Anand maintained the highest seed quality under both the high temperature and drought stress.

    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-10) SHRUTHI, K; Balakrishna, P
    A laboratory experiment was conducted during 2014-15 with a view to study the effect of media, temperatures, seed treatment and accelerated aging on the seed quality parameters of Kalmegh (Andrographis paniculata Nees.), Garden rue (Ruta graveolens L.) and Roselle (Hibiscus sabdariffa Var. sabdariffa L.) seeds. The experimental results revealed that the top of paper method (TP) at 20 and 25 0C recorded highest percentage of germination (60 and 40 %), seedling vigour index-I (1240 and 657) and seedling vigour index-II (730 and 598) in Kalmegh and Garden rue seeds respectively. Whereas, the between paper method (BP) at 30 0C recorded the highest seed germination (78 %), seedling vigour index-I (2499) and seedling vigour index-II (2036) in Roselle seeds. Among the different seed treatments the hot water treatment (50 0C for 5 min.) recorded the higher seed germination (66 and 82 %), seedling vigour index-I (1110 and 2055) and seedling vigour index-II (565 and 1783) in Kalmegh and Roselle seeds respectively. Whereas, KNO3 treatment recorded the higher seed germination (61.3 %), seedling vigour index-I (950) and seedling vigour index-II (598) in Garden rue seeds. While, studying the effect of accelerated ageing test on seed quality of these medicinal plants, have recorded the decreased seed viability and seedling vigour (speed of germination, germination percentage, seedling vigour index I&II) and increased biochemical parameter (electrical conductivity) progressively with the increment in ageing period (7, 8, 9 and 10 DAA).
