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.

    SELECTION OF INDIGENOUS FOREST TREE SPECIES RESPONDING TO HIGH CARBON DIOXIDE (CO2) CONCENTRATION
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-07-30) PRIYANKA, V. S.; Mahadeva Murthy, M.
    Rise in the atmospheric concentration of greenhouse gases under global climate change warrants an urgent need to understand the mechanisms associated with plant growth and development. Selection of appropriate indigenous forest tree species would help in sequestering the increasing CO2 levels in the atmosphere. Therefore, the present study was conducted with two levels of CO2 (ambient 400 ppm and elevated 550 ppm) and one year old seedlings of indigenous species, namely Syzygium cumini, Dalbergia latifolia, Eugenia jambolana, Pterocarpus marsupium, Terminalia catappa, Mamia surgi, Pongamia pinnata and Madhuca latifolia. The leaf area and leaf dry weights were higher in Eugenia jambolana under CO2 enrichment. The dry matter production in Syzygium cumini (67.8 g/plant), Terminalia catappa (54.4 g/plant), Eugenia jambolana (53.9 g/plant) and Pongamia pinnata (52.9 g/plant) were higher at elevated CO2 levels. The root/ shoot ratio was decreased in all species except the Madhuca with higher CO2 concentration. An increased NAR was observed in Pongamia pinnata (805.4 mg. dm-2). Photosynthetic rate, leaf area duration and biomass production were high in Syzygium cumini at elevated CO2 concentration. In overall, the elevated CO2 resulted in higher water use efficiency through decreased stomatal conductances with relatively higher photosynthetic rates. Although, the data on gas exchange traits needs to be confirmed, based on the growth parameters, Syzygium cumini, Pterocarpus marsupium, Terminalia catappa, Mamia surgi and Eugenia jambolana found responsive to elevated CO2. These species can be recommended for afforestation as these indigenous species possess rapid growth rates and CO2 sequestration.
