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.

    LAND RESOURCE ASSESSMENT OF NAGENAHALLI WATERSHED, DODDABALLAPUR TALUK, BANGALORE RURAL DISTRICT USING REMOTE SENSING AND GIS TECHNIQUES.
    (University of Agricultural Sciences, Bangalore, 2010-08-15) NALINA, C. N.; Anil Kumar, K. S.
    Comprehensive land resources information is important for efficient land use planning and fertilizer being the costliest input, the use of plant nutrients has to be need based. Hence a detailed characterization of land resources were undertaken in Nagenahalli watershed, located between 13º 22′ 20.2″ to 13º 22′ 58″ N latitude and 77º 32′ 52.4″ to 77º 33′ 27.7″ E longitude and an elevation between 911 to 930 m above MSL covering 225.2 ha in Doddaballapur taluk, Bangalore Rural District. Climate of the area is semiarid tropical with a mean annual rainfall of 826.1 mm and temperature of 23.8 °C. Cadestral map, satellite imagery and Google Earth images were used in conjunction with SOI toposheets to map the land use, study physiography-soil relationships and to prepare the soil map. The information gathered has been processed under GIS environment to generate thematic maps on crop suitability and fertility capability. Soils are developed from granite and its colluvium. Horizon-wise soil morphological, physical and chemical properties of major soils were studied. Composite plot-wise surface soil samples were analysed for fertility. Five soil series have been identified and mapped into 15 soil mapping units. All the soil series identified are Nagenahalli- a (Na-Typic Kandiustalf), Nagenahalli-b (Nb-Typic Kandiustalf), Nagenahalli-c (Nc- Kanhaplic Haplustalfs), Nagenahalli-d (Nd-Ultic Paleustalfs) and Nagenahalli-e (Ne- Kandic Paleustalfs) are very deep except Nc, which is moderately shallow. The soils of Na and Nb are red with low CEC and low base saturation and having kandic horizon and soils of Na- series have gravel layer below 50 cm. Nc series covers largest area of 87.8 ha followed by Nd series, covering an area of 50.8 ha. The soils of Nc series are fine-loamy and are non-gravelly with very less clay content, while the soils of Nd and Ne series are fine, red and very gravelly. Gravel layer starts below 40 cm and have medium CEC. Major surface soils of the study area are non-gravelly and sandy clay loam (99 ha) textured and are poor in organic carbon (0.3 to 0.4 %) moderately or strongly acidic (176 ha) and low in available N (174 ha) and K (157 ha) but rich in P (170 ha) and sufficient (176 ha) in Zn. Major soils are suited to maize, ragi, and vegetables. Eucalyptus plantations on sloppy eroded lands (62.8 ha) can be retained but not on prime lands.
