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 POD BORERS OF DOLICHOS BEAN, Lablab purpureus L. (Sweet) AND THEIR MANAGEMENT
    (University of Agricultural Sciences, Bangalore, 2009-07-15) MALLIKARJUNA, J.; Ashok Kumar, C. T.
    A total of eight different pod borers belonging to different genera have been recorded on Dolichos bean under Bengaluru condition. Among them, Helicoverpa armigera was found to be major and its incidence was comparatively more than the other pod borers such as Adisura atkinsoni, Sphenarches caffer, Maruca testulalis, Etiella zinckenella, Exelastis atomosa, Lampides boeticus and Callosobruchus chinensis which were recorded at low incidence level. Maximum diversity (H=2.00) was observed among the pod borers on third week of December as measured by using Shannon Weiner index of diversity. All the pod borers have shown negative correlation with maximum temperature and rainfall while positive with relative humidity. H.armigera was found to be relatively more abundant with 17-71 % incidence. Among the indigenous materials, GCK (0.5%) was found to be very effective with respect to larval reduction (58.62%), pod damage (19.56%), seed damage (28.11%) and pod yield (8.3 q/ha) and among the new insecticide molecules, flubendiamide 24% + thiacloprid 24-48% SC was proved to be very effective with respect to larval reduction (79.25%), pod damage (13.13%), seed damage (18.41%) and pod yield (16.35 q/ha). Highest net returns obtained with GCK (Rs.4500) and Indoxacarb (Rs.10250). However, GCK (0.5%) and Fenvalerate 20 EC have been recorded highest BC ratio of 13.26 and 7.14 respectively among indigenous materials and new insecticide molecules. GL 248, GL 45 and GL 133 was proved to be highly resistant germplasms which recorded 00-15.15 % pod damage and first two lines were non preferred for oviposition which received a mean of 1.36 and 5.28 eggs per 10 inflorescences, respectively. Pod texture and fragrance have shown significant relation with larval boring while foliage colour has shown significant relation with oviposition.
