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.

    RESIDUAL TOXICITY OF SOME NEW INSECTICIDES TO HONEY BEE, Apis cerana indica F. (Hymenoptera:Apidae).
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 39403) YESHWANTH, H.M; GOWDA, GAVI
    Some new insecticides belonging to different groups viz., buprofezin (thiadiazine), novaluron (acylurea compound), indoxacarb (oxadiazine), methomyl, thiodicarb (carbamates), imidacloprid (neonicotinoid), lambda-cyhalothrin (synthetic pyrethroid),fenazaquin(quinazoline)and spinosad (actinomycetes toxin) were tested for their residual toxicity by exposing the workers of Apis cerana indica to treated leaves of sunflower at different days after treatment for different durations. The residual toxicity of spray deposits of different insecticides on sunflower leaves to A. c. indica varied with chemicals. On the day of application, all the chemicals except novaluron and lambdacyhalothrin recorded the mean mortality ofmorethan 25 per cent. i.e. imidacloprid, spinosad and methomyl recorded the higher per cent mortality levels. Based on the hazard ratio (field recommended dose divided by laboratory LD50 value), the chemicals thiodicarb, buprofezin and methomyl were grouped under moderately toxic group, while imidacloprid, spinosad, indoxacarb, novaluron, lambdacyhalothrin and fenazaquin were grouped as non-toxic chemicals. The contact toxicity test of different insecticides to A. c. indica varied considerably. Based on the LD50 values thiodicarb was most toxic compound followed by imidacloprid, indoxacarb, lambda-cyhalothrin, methomyl, spinosad, novaluron and buprofezin.

    STUDIES ON SOME BEHAVIOURAL ASPECTS OF LITTLE BEE, Apisflorea Fab. (HYMENOPTERA: APIDAE)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK ,BANGALORE, 39344) SHWETHA, B.V; Gavi Gowda
    The present investigations were carried out to study the pasturage sources, melissopalynology, palynology, foraging distance, swarming and its prevention, absconding and post absconding behaviour in A. florea. Foraging activity of A. florea in comparison with A. cerana during different weather conditions and Pollinator fauna and abundance oi A. florea in some selected plant species were also studied. Total of 147 plant species belonging to 48 families were found to be foraged by A. florea. Melissopalynological studies revealed that Cuphea micrantha, Cocos nucifera, Psidium guajava. Eucalyptus sp., Foeniculum vulgare, Mangifera indica, Pongamia pinnata, Peltophorum ferrugineum, Tamarindus indica, Callistephus chinensis and Brazil plant were dominant in the A. florea honey samples analysed from GKVK, Bangalore. Palynological investigations made on pollen loads of A. florea foragers revealed that Guizotia abyssinica, Helianthus amus, Anacardium occidentale, Mangifera indica, Punica granatum, Foeniculum vulgare, Burscera delpechiana, Mentha spicata, Nepeta cataria, Ocimum kilimandscharium, Raphanus sativus, Cuphea micrantha, Antigonon leptopus, Callistemon lanceolus, Eucalyptus sp., Simaruba glauca, Pongamia pinnata and Tamarindus indica are the dominant pollen types in GKVK campus. Swarm preparation was observed from November to March. Absconding was observed during February to March. Punching of queen and drone cells delayed the swarming process by 11-98 days. After the desertion, workers from the same colony were found lo lelurii oud collect tlic wax from the honey portion und upper penpliuiy of the comb. A. cerana and A. florea were more active during bright sunny days than cloudy days. However A. cerana recorded higher activity than A. florea during sunny as well as cloudy days. Among the insects species visited flowers of radish, niger, rose apple and simaruba, A. florea was dominant.

    INFORMATION MANAGEMENT SYSTEM OF DEPARTMENT OF AGRICULTURE FOR FARM PRODUCTION IN KARNATAKA STATE, INDIA
    (UNIVERSITY OF AGRICULTURAL SCIENCES BANGALORE, 37996) ZUBER MOHAMMED, SEBSIBIE; SUNDRASWAMY, B
    The investigation was conducted during 2001/2002 to study the Information Management System of Department of Agriculture for Farm Production in Karnataka State. Dharwad district was purposively selected for the study. During the time of investigation, the Department of Agriculture was positioned with 30 Assistant Agricultural Officers (AAOs) and 68 Agricultural Assistants (AAs). All those 98 extension personnel were selected as respondents of the study. The data were collected by mailed questionnaires developed for the study. Analysis of the collected data was done using different statistical tools. The important findings of the study were; on overall Information indices comparison, AAOs had better knowledge than AAs in information management system. The ranking of items belonged to different stages of information management system by AAOs and AAs were remained statistically same except in a few stages. Factors like education level, scientific orientation and leadership ability were positively and significantly related with information management system of AAOs. Similarly contact span, scientific orientation and leadership ability were positively and significantly related with information management system of AAs. Information on some of crop production techniques, weather forecasting, market and farm input were perceived as inadequate by AAOs and AAs for decision making. The study also revealed the main constraints faced by AAOs and AAs in information management system. The findings of information indices indicated that there is a need to increase the information management system of AAOs and AAs. The positive and significant f relationship of the socio-psychological factors with information management system of AAOs and AAs pinpoints to the need for continuous and well planned efforts to strengthen and develop these characteristics among AAOs and AAs. Relevant, accurate and timely farm information for effective decision making is highly required by both AAOs and AAs. This can be achieved through developing better farm information flow strategies
