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.

    BIOLOGICAL CONTROL OF PIGEONPEA CYST NEMATODE (Heterodera cajani K03HY) INFECTING PIGEONPEA (Cajanus cajan (L.) MILL.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1999-08-30) KANNAN, C.; LINGARAJU, S.
    Rhizosphere soils from pigeonpea monocropped fields of Gulbarga district, Karnataka were screened for isolation of native antagonistic fungi against the pigeonpea cyst nematode, viz. B. cajani. Accordingly five fungal species, viz. AspergiIlus nidulans {Emericella niduians), Penicillium sp. Fusarium sp. Botryodiplodia theohromae and Cladosporium herbarum were isolated. This is the first report of C. herharum parasitising the cysts of H. cajani. C. herbarum and B. theobromae were compared for their biocontrol efficiency. C. herbarum was more rapid in parasitising the cysts of H. cajani (97.00% of cysts in 96 hours of inoculation) than B. theobromae (49.00% in the same time). Pathogenicity tests confirmed that C. herbarum was nonpathogenic to pigeonpea. C. herbarum @ 25 g giant culture per pot reduced the cyst population of H. cajani to the tune of 53.77 per cent. Similarly, organic amendments, viz. farm yard manure, pigeonpea leaf litter, poultry manure, sorghum root bits and neem cake applied at different doses to the soil were able to reduce the cyst population in the range of 18.14 to 45.44 per cent. Combined application of C. herbarum and the organic amendments resulted in the maximum reduction of the cysts (79.30%). Application of different organic amendments to the soil resulted in the increase in population of C. herbarum in the range of 19.33 to 28.06 per cent. H. cajani reduced the total biomass of pigeonpea to the tune of 34.22 per cent within 90 days of inoculation, but on application of C. herbarum and organic amendments to the soil H. cajani was effectively controlled and total biomass was increased in the range of 21.33 to 45.78 per cent. C. herbarum was suitable for both seed and soil formulations. Both these formulations can be stored for 3 months under room conditions.
