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.

    INNOVATIVE APPROACHES THROUGH HYDROPONICS AND AEROPONICS FOR HYBRID SEED PRODUCTION IN TOMATO (Solanum lycopersicum L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2019-12-28) RAJATHA, K. D.; RAJENDRA PRASAD, S.
    An experiment was designed to evaluate the suitability of the hydroponics (M2) and aeroponics (M3) methods over conventional method (M1) for hybrid seed production of tomato. An initial trial for standardization of nutrients and pH for aeroponics and hydroponics was conducted. Among the 6 different nutrient solutions the crop performance was better in Hoagland’s solution with pH range 5.5-7. The main trial was conducted for hybrid seed production in tomato with 12 treatments comprising 3 methods of production, 2 parental lines (TAG 1F and TAG 2F) and 2 different seed treatment (S1: Control and S2: Thiram @ 2 g kg-1 + chlorpyrifos @3 g kg-). The experiment was laid in FCRD design with three replications. The results of the revealed that, among the parental lines, TAG 1F performed better under all the methods of hybrid seed production. Aeroponics and hydroponics performed better than the conventional method due to better availability of nutrients and aeration, huge root biomass in soil-less system. Aeroponics showed the significantly higher plant length (140.94 cm), LAI (6.99), early fruit maturity (95.23 days), fruit weight (124.54 g), total biomass (106.44mg) and test weight (0.39 g). Similarly hydroponics showed the significantly higher number of fruit plant-1 (45.84), seed yield fruit-1 (13.6mg) and number of seeds per fruit-1 (97.65) but conventional method showed the higher plant spread (87.35 cm). Although the cost incurred was comparatively higher is soil-less method, the gross return was 94.68 per cent higher under aeroponics and 79.22 per cent higher under hydroponics compared to conventional method. The return per rupee (B:C ratio) was found higher in aeroponics (2.08) followed by hydroponics (1.97) and lower under conventional method (1.87). It is inferred that, soil-less agriculture could be a promising tool for quality and healthy hybrid tomato seed production throughout the year with in protected cultivation.

    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.
