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.

    EFFECT OF SOIL AND FOLIAR APPLICATION OF BORON ON SOIL PROPERTIES, GROWTH, YIELD AND QUALITY OF GREEN GRAM (Vigna radiata L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 2020-11-25) RAMY, N.; MAMATHA, B.
    A field experiment entitled "Effect of soil and foliar application of boron on soil properties, growth, yield and quality of green gram (Vigna radiata L.)" was carried out during Kharif 2019-20 at ZARS, UAS, GKVK, Bangalore. The experiment comprised of twelve treatments, replicated thrice with RCBD. The results indicated that significantly higher available nitrogen (275.3 kg ha-1), available potassium (156.74 kg ha-1), exchangeable calcium (2.88 c mol (p) kg-1) and available sulphur (275.3 kg ha-1) were recorded in package of practice (FYM 7.50 t ha-1 + NPK 12.5:25:12.5 kg ha-1 + ZnSO4 10 kg ha-1), while significantly higher available phosphorus (28.12 kg ha-1) and available boron (0.57 mg kg-1) were recorded in treatment which received soil application of borax at 7.50 kg ha-1along with package of practice. Whereas, soil application of borax at 2.50 kg ha-1 + foliar application of boric acid at 0.1 % along with package of practice recorded significantly higher plant height (50.82 cm), number of branches plant-1 (8.29), seed yield (10.19 q ha-1), haulm yield (2.17 t ha-1) and B:C ratio (1.96). While, significantly higher crude protein content (25.38 %) in seed was noticed in treatment which received soil application of borax at 5.00 kg ha-1 + foliar application of boric acid at 0.1 % along with package of practice. However, soil application of borax at 7.5 kg ha-1along with package of practice recorded significantly higher uptake of boron (36.62 and 64.33 g ha-1) by seed and haulm of green gram, respectively.

    EFFECT OF TREATED EFFLUENT FROM BEVERAGE INDUSTRY ON SOIL PROPERTIES, GROWTH AND YIELD OF MAIZE [Zea mays (L.)] – COWPEA [Vigna unguiculata (L.)] CROPPING SEQUENCE
    (University of Agricultural Sciences, Bangalore, 2021-03-17) MALLESH, , K. U.; MALLESH, , K. U.; Chikkaramapa, T; Chikkaramapa, T
    Field experiment was carried out at Hindustan Coca-Cola Beverages Pvt. Ltd.Bidadi Industrial Area, Bidadi Hobli, Ramanagar Taluk, during the year 2017-18 and simultaneously pot culture experiment was carried out under greenhouse condition in the Department of soil science and Agricultural Chemistry, College of Agriculture, UAS, GKVK, Bengaluru. The beverage industry effluent was slightly alkaline in pH (8.21 ±0.20). Electrical conductivity was medium (1.75±0.14 dS m-1), BOD (5.23± 0.36 mg L-1) and COD (20.44 ± 1.07 mg L-1) however low in plant nutrients. In maize-cowpea cropping sequence among the treatments which received, RDF + gypsum + Irrigation with treated effluent from beverage industry recorded significantly higher kernel and stover yield in maize (6932.56 and 8145.94 kg ha-1), seed and haulm yield of cowpea (1023.33 and 2411.86 kg ha-1) and in pot culture experiment kernel yield and stover yield(41.45 and 51.82 g pot-1) respectively, compared to other treatments. Soil properties like pH, EC and exchangeable Na were higher in treatment receiving RDF + Irrigation with treated effluent from beverage industry while, OC, available N, P2O5, K2O, secondary and micronutrients were higher in treatment receiving RDF + gypsum + Irrigation with treated effluent from beverage industry. Among the treatments, significantly lower kernel and stover yield in maize (5935.40 and 6974.26 kg ha-1), seed and haulm yield in cowpea (876.14 and 2064.95 kg ha-1) and in pot culture experiment kernel yield and stover yield(27.58 and 34.48 g pot-1) respectively, was recorded in treatment which received RDF + Irrigation with treated effluent from beverage industry. RDF + gypsum + irrigation with fresh water (0.302) recorded significantly higher harvest index compared to all other treatments. Higher benefit cost ratio were recorded in the treatment which received cycle of 1 irrigation with fresh water + 2 irrigations with beverage industry effluent + RDF + gypsum (2.42). Gypsum had shown significant effect in increasing the yield of the crop by reducing the effect of sodium on crop growth.

    STUDY OF DIFFERENT FORMS OF ZINC AND IRON AND THEIR RELATION WITH OTHER PROPERTIES OF SOILS UNDER RICE BASED CROPPING SYSTEM IN CHAMARAJANAGAR DISTRICT
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2009-07-10) MAHENDRA KUMAR, M B; SUBBARAYAPPA, C T
    An investigation was under taken to study the available zinc and iron status and distribution of different forms of zinc and iron in soils under paddy land use in Chamarajanagar district. Seventy five surface soil samples were collected from fifteen villages belonging to Chamarajanagar, Yelandur and Kollegal taluks of Chamarajanagar district. These samples were analyzed for available zinc and iron status and different forms of zinc and iron. The results revealed that available zinc and iron ranged from 0.69 to 2.96 and 6.09 to 32.14 mg kg-1, respectively. Distribution of different forms of zinc viz., water soluble, sorbed, easily reducible manganese bound, carbonate bound, organic matter bound and iron and aluminium oxides bound zinc ranged from 0.02 to 0.18, 0.64 to 5.31, 0.21 to 1.87, 0.11 to 3.39, 0.02 to 1.48 and 1.82 to11.68 mg kg-1 respectively and distribution of different forms of iron viz., exchangeable iron, organic matter bound, manganese oxides bound, amorphous iron oxides and crystalline iron oxides iron in these soils ranged from 2.68 to 12.12, 1.02 to 1.97, 14.7 to 92.3, 178 to 1020 and 167 to 1046 mg kg-1, respectively. Correlation studies indicated that available zinc recorded a significant and negative correlation with clay (r=-0.24*) and available iron recorded a significant and positive correlation with CaCO3 (r=0.54**) and negatively with pH of the soils (r=- 0.50**). All the zinc and iron fractions were correlated positively with each other except the easily reducible manganese bound zinc and organic matter bound iron, which recorded negative correlation with other fractions indicating the existence of a dynamic equilibrium between the zinc and iron fractions.
