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.

    STUDEIS ON PROPERTIES OF GROUNDNUT GROWING SOILS OF U.K.P (PHASE -I) COMMAND AREA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 19-08-98) SANGAYYA, . R. P.; Dasog, Dr.G.S.
    A sutdy was underteken on groundnut growing red & black soils of UKP (Phase-I) command area in North - eastern dry zone of Karnataka to understand the moiphological, physical and chemical properties and to evaluate their suitability for irrigation and fw cultivation of groundnut Five pedons and fifteen surface soil samples derived from granite gneiss were studied and a lime stone derived black soil pedon was also included for comparision. The soils were deep to veiy deep , sandy loam to loamy sand in texture with colour hue of 2.5YR and 5YR with weakly to moderately developed subangular blocky structure. Red soil contained high sand and low silt content Clay movement was apparent in Narayanpur, Kodekal and kakkera pedons where as Huansigi pedon was clayey throughout the depth. The moisture retention at 33kPa and 1500kPa followed the trend of clay in all the pedons. The pH varied from slightly alkaline to moderately alkaline and increased with depth. The exchangeble calcium was the dominant cation followed by magnesium, sodium and potassimn in all the soils. The available nitrogen content ranged from 123 to 296 kg / ha. The available phos phorous and potassium was medium. The uptake of N was more in red soils than black soils but no such difference was noticed for P and K, A high positive correlation between availabile N , P, K and Calcium of soils and tbeir uptake in kemals was observed. The pod and kemal yield was more in red soils than black soils. The soil suitabibty evaluation for groundnut was attempted based on climatic and soil requirements. The overall suitability was rated as suitable (S2) and sligthly suitable (S3) soils for groundnut in respect of red and black soils, respectively.

    CLAY MINERALOGY OF RED AND LATERITIC SOILS OF NORTH KARNATAKA
    (University of Agricultural Sciences, Bangalore, 1996) SURPUR, RAVI S; DASOG, G S
    Clay mineralogy of four red and three lateritic soils from north Karnataka were studied with an objective to understand the relative abundance of clay minerals and their transformations in these soils.Both red and lateritic soil clays exhibited greater CEC (18.4 to 55.4 Cmol Kg-1 except Jamboti. Specific surface of clays closely followed the trend of CEC and ranged from 126 to 343 m2g-1 The molar ratio of Si02/R203 ranged from 1.95 to 2.33 and Si02/Al203 ranged from 2.06 to 2.52. Both these ratios were not distinctly different among the clays of two soil groups. The amorphous ferri-aluminosilicate content ranged from 8.24 to 14.26 per cent in these clays. The molar Si02/Al203 ratio of the constituents of the clays extracted by boiling in 0.5N NaOH followed by CBD was in the range of 1.33 to 2.87. The FeOOH component was in the range of 21.60 to 47.97 per centCommon to all soils the presence of a peak around 2.5nm ascribable to interstratified mica-smectite/vermiculite. Discrete vermiculite was present in Ranebennur and Kulageri pedons. Kaolinite content was more in lateritic pedons compared to red soils. Mica is present in all the pedons to varying degrees. The first order peak of mica showed shoulders on the low angle side and broadening on Mg-saturation and glycerol solvation indicate that the mica is undergoing weathering. The data on chemical composition, CEC, specific surface and X-ray diffraction of clay fraction it can be stated that interstratified mica-smectite/vermiculite, mica, smectite and vermiculite, kaolinite are the minerals identified in these soils. Quartz is present in all the pedons to a small extent, as evidenced by peak at 0.426nm and 0.333nm.The probable of pathway of weathering and transformation is mica on weathering has transformed to interstratified mica- smectite/vermiculite —> smectite/vermiculite —> kaolinite.
