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 carbon and nutrient dynamics in different land use systems of a watershed in the western ghat
    (University of Agricultural Sciences, Bengaluru, 06-05-13) K. M, Shivakumar; S. S, Prakash
    The changes in land use systems from natural vegetation to different manmade land use systems influence the physical, chemical and biological properties of soil. Hence, investigation was carried out to study the carbon and nutrient dynamics in different land use systems in a watershed of WesternGhat of Karnataka. The land use systems selected for the study consisted both manmade systems (Agriculture: paddy; Horticulture: coffee,arecanut, tea and banana); forest plantation (accacia and teak) and natural systems (Evergreen, semi-evergreen and grassland).Both litter and soil samples were collected during pre and post monsoon seasons were analysed for various parameter. Litter production among the land use systems was in order of grassland (2.48 t ha-1) < banana (2.50 t ha-1) arecanut (4.45 t ha-1) < acacia (4.85 t ha-1) < tea (5.15 t ha-1) < evergreen forest (6.47 t ha-1). The litter of evergreen forest had significantly higher carbon content (52.73 %), consequently potential C returned (3411 kg ha-1) was higher. The nitrogen (2.50%),phosphorous(0.45%) and potassium (1.75%) content was higher in coffee litter. The soil under evergreen and semi-evergreen forestand coffee, had lower bulk density and higher MWHC,SOC (2.73%, 2.57% and 2.47%), TOC, SMB-N andavailable nitrogen and phosphorus and micronutrient status compared to soils under other land use. The evergreen land use systems recorded higher dehydrogenase and acid phosphatase activity followed by semi-evergreen and coffee, while urease activity was significantly higher in coffee land use system. Soil organic carbon showed positive and significant correlation with TOC, TN, TP, TK SMB-C SMB-N,dehydrogenase and acidphosphatase activity.The land use systems influenced organic carbon and nutrient dynamics in soil due to differential litter turnover as well as organic matter and nutrient added from external source.
