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 Azospirillum ISOLATES OF ORNAMENTAL PLANTS AND THEIR EFFECT ON Gaillardia pulchella var picta Fouger
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-08) GADAGI, RAVI; KULKARNI, J. H.
    Investigations were carried out on the isolation, identification, genetic diversity, scrcening of Azospirillum for beneficial traits and their inoculation effect on the growth and flowering of Gaillardia. Attempts were made to improve tlie nitrogen fixing efficiency of Azospirillum through mutagensis. From tlie present investigation, it can be concluded that Azospihllum is a common inhabitant of roots of ornamental plants. Of the 88 isolations made, 55 per cent of isolate were Azospirillum lipofemm while Azospirillum bmsilense represented 41.57 per cent. The nitrogen fixation by Azospirillum isolates in the semi solid medium ranged Irom 1.40 (OAD-36 and OAD-72) to 20.54 (OAD-2) mg g-1 of malate. The ability to fix dinitrogen was also confiiined by acetylene reduction assay. Although all the Azospirillum isolates could produce variable quantity of lAA and GA, strain OAD-57 produced the highest amount of plant growth promoting substances. The genetic diversity of Azospirillum isolates was analyzed tlirough iiitiinsic antibiotic resistance, protein and plasmid profile. The isolates showed wide diversity with respect to intrinsic antibiotic resistance. However using the protein finger printing two definite groups of Azospirillum could discerned. All the isolates contained only one plasmid (22 kb). Based on preliminary screening of all the isolates under pot culture, seven efficient isolates were selected for further field study. From the field experiment, it could be concluded that OAD-2 can play an impoiiant role in tlie N-nutrition of Gaillardia pulchella. Further 25 AziĀ® and EDAR mutants were obtained through NTG mutagenesis. These mutants had highei* nitrogenase activity and in vitro N fixation (g-1 malate.) The AziR OAD-904, and EDAR OAD-209 perfoimed better tlian their respective wild type isolates, m pot cultures in augmenting plant growth and N-uptake of Gaillardia puldiella.
