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.

    STUDIES ON INSECT PESTS OF GRAIN AMARANTH (Amaranthus sp.) AND THEIR MANAGEMENT
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-09-26) ANIL; Srinivas Reddy, K. M.
    The present investigation revealed nineteen insect pests on grain amaranth, namely leaf webber (Hymenia recurvalis Fab.), stem weevil (Hypolixus truncatulus Fab.), ear head caterpillar (Helicoverpa armigera Hubn.), leaf beetle (Gametis versicolor Fab.), Yellow winged grasshopper (Gastrimargus species Fab.), Brown stripped beetle (Clinteria kluge Hope.), amaranth bug (Cletus species Fab.), horned coreid bug (Cletomorpha sp Fab.), wingless grasshopper (Neorthacris acuticeps Bol.), ash weevil (Myllocerus discolor Boh.), (Myllocerus dorsatus Fab.), white spotted flea beetle (Monolepta signata Oliv.), seed bug (Spilostetchus hospes Fab.), (Graptostetchus servus Fab.), (Nysius species Dall.), mirid bug (Eurystylus sp. Stal.), Stink bug (Hyalomorpha picus Fab.) and other insect pests. The major natural enemies recorded were coccinellids, black bug, assassin bug and braconid wasp. Thirty two grain amaranth genotypes were screened for leaf webber, of which KBGA-5, RHGA-13-1, RHGA-13-2, RMA-7, MGA- 15, KBGA-4, BGA-38, BGA-43, SKGPA-75, RJAS-08-17, MGA-12, KBGA-7, IC- 032193 and IC-035713 were found tolerant. KBGA-9, BGA-7-1, BGA-29, SKKGPA-86, RHGA-11, BGA-2 and SKGPA-74 were moderately tolerant to leaf webber. Among the insecticides evaluated, emamectin benzoate 5% SG @ 0.25 g/l and indoxacarb 15.8% EC @ 0.5 ml/l were found to be more superior against leaf webber and acephate 75 SP @ 1.5 g/l and imidacloprid 17.8 SL @ 0.3 ml/l superior against coreid bug over other treatment respectively. The maximum grain yield (13.98 q/ha) with IBCR (Incremental Benefit Cost Ratio) of 26.00 was evident from the plots treated with imidacloprid 17.8 SL, followed by profenophos 50 EC with seed yield of 13.59 q/ha with IBCR Rs. 29.40.
