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.

    INFLUENCE OF SITE FACTORS ON GROWTH OF TEAK STANDS IN THE WESTERN GHATS OF KARNATAKA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-10) APARANJI, SHIVAKUMAR L.; CHAJVDRASEKHARAIAH, Dr. A. M.
    Teak (Tectona grandis Linn, f.) Is one of the most well known and popular timber species of high quality that is grown under varied environmental conditions. To elucidate the effect of rainfall, temperature and a few soil factors, a study was conducted on similar-aged teak plantations (19-20 years old) spread over six bioclimatic zones established by the KFD. Temperature rainfall, all edaphic factors studied and associated vegetation showed a major influence on its growth and yield as indicated by analysis of variance. Performance of teak for various growth and yield measurements were found to be better in the bioclimatic zone IV which was characterized by higher temperature (>23°C) and medium rainfall (1500-2000 mm). Contrast analysis showed that about 61 per cent more growth under zones of higher temperature (II, IV and VI) when compared to lower temperature range (I, III and V) suggesting positive response of teak to higher temperature regime. Similarly higher performance of teak was noticed in medium rainfall zones compared to zones of higher (2000-5000 mm) or lower rainfall (1200-1500 mm). Correlation studies indicated to be negative between bulk density and particle density with growth and yield of teak and positive association with porosity. Most of the chemical properties including soil nutrients have positive effect on the performance of teak. However pH was found to be negatively correlated with the growth parameters. Major soil nutrients viz., available nitrogen, phosphorous and potassium have resulted positive correlation with growth and yield of Teak. Teak stands with higher invasive species show restricted growth than those plantations.
