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.

    ASSESSMENT OF TREE DIVERSITY, PRODUCTIVITY AND CARBON SEQUESTRATION POTENTIAL OF DIFFERENT AGROFORESTRY SYSTEMS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-10-13) DODDABASAWA; Mahadeva Murthy, M.
    The present investigation ‘Assessment of tree diversity, productivity and carbon sequestration potential of different agroforestry systems’ was carried out during 2015-16 and 2016-17 in north eastern Karnataka covering six districts on farmers fields. Bund and boundary plantings were the major traditional agroforestry systems practiced by the farmers in both rainfed and irrigated ecosystems. Tree number varied with farm holding size and kind of agroforestry systems and was positively correlated. Shannon’s diversity index was higher with small farmer followed by medium and large farmer and mean number of species was more influenced by the prevailing ecological condition of the location. 27 tree species belonging to 15 plant families with 92.6 per cent being indigenous were recorded in rainfed ecosystem. Azadirachta indica was the most predominant species followed by Acacia nilotica, Ziziphus mauritiana and Tamarindus indicus. While under irrigated ecosystem, 52 tree species belonging to 25 families with 85 per cent being indigenous were dominated by Tectona grandis followed by Azadirachta indica and Cocos nucifera. The grain yields of pigeonpea in association with neem under rainfed ecosystem and teak under irrigated ecosystem were lower near the tree line at 5 m distance compared to at 10 m and 15 m distances, however, different agroforestry systems did not reveal significant variation in yield. In all, yield was lower in agroforestry systems compared to control. Nevertheless, positive influences of agroforestry system were visible on soil properties, energy use efficiency, carbon sequestration and carbon sustainability compared to food grain based system, and trees in agroforestry systems accounted for 50 to 70 per cent higher carbon sequestration than the conventional agriculture.
