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.

    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.

    MICRONUTRIENT FERTILITY MAP OF GHATAPRABHA COMMAND AREA OF BELGAUM DISTRICT
    (University of Agricultural Sciences, Bangalore, 1996) L B, ASHOK; DODDAMANl, V S
    Studies on status of micronutrient cations and response of maize to zinc and iron levels in red soil of Ghataprabha command area of Belgaum district of North Karnataka revealed that the soils in different taluks namely Gokak, Raibag, Chikkodi, Athani and Hukkeri, these soils are alkaline in soil reaction and normal in electrical conductivity. The range and mean values of available iron, manganese, copper and zinc in soils of Ghataprabha command area of Belgaum district vary from 0.32 to 11.02, 0.37 to 27.73, 0.54 to 8.28 and 0.03 to 3.88 ppm with a mean value of 3.77, 8.00, 2.54 and 0.51 ppm respectively. As per the limits of <2.5, 2.5 to 4.5 and >4.5 ppm as deficient, marginal and sufficient in available iron, 21.1, 52.0 and 26.9 per cent of samples fall under deficientmarginal and sufficient category respectively. In respect of available manganese, majority of the soil samples (97.1%) fall under category of sufficient (>2.0 ppm) and reamaining (2.9%) samples fall under deficient category (<2.0 ppm). As per deficiency (<0.2 ppm) and sufficient (>0.2 ppm) category for available copper, all the soils of Ghataprabha command area of Belgaum district fall under sufficient category. In case of zinc. 76.9, 9.1 and 14.0 per cent of samples fall underdeficiency (<0.6 ppm), marginal (0.6-1.0 ppm) and sufficient (>1.0 ppm) category respectively. The response of maize to zinc and iron in red soil of command area used for pot culture having high and marginal in available zinc and iron, indicated that there was no significant increase in dry matter production, but showed significant increase in concentration of the nutrients.

    STUDIES ON CONTRIBUTION OF VAMF TOP NUTRITION OF BRINJAL (Solanummelongenal) IN AN ALFISOL
    (University of Agricultural Sciences, Bangalore, 1996) PANDITH, B M M K; CHANNAL, H T
    A field experiment was conducted at Olericulture section, Division of Horticulture, University of Agricultural Sciences, Dharwad during summer season of 1995-96 to study the contribution of vesicular arbuscular mycorrhizal fungus (VAMF) to phosphorus nutrition of brinjal in an alfisol. The experiment was laid out in factorial randomised block design with eight treatment combinations, comprising of four phosphorus levels (0, 50, 75 and 100 kg P2O5 per ha) with and without VAMF inoculation. The treatments were replicated three times.Inoculated plants produced significantly higher fruit yield of brinjal (57.00 t/ha) than uninoculated plants (46.08 t/ha) as a result of higher growth and yield components, higher drymatter production, higher per cent root colonization, spore count and higher P, Cu, Fe, Zn and Mn uptake.Application of 75 kg P2O5 per ha recorded higher fruit yield (56.50 t/ha) and it was 26.48 and 5.61 per cent higher over control (44.67 t/ha) and 100 kg P2O5 per ha (53.50 t/ha). Higher yield was found to be consequence of higher fruit volume, fruit weight, higher dry matter accumulation and higher P uptake by the plants.Combined application of VAMF and 75 kg P2O5 per ha (M1P75) produced significantly by the highest fruit yield (65.00 t/ha) over any other treatment combination. Not only that it also helped to improve certain quality parameters such as total soluble sugars, free phenols and crude protein content of the fruits. Thus indicating the usefulness of VAMF (Glomus fasciculatum) in reducing the phosphorus application to brinjal crop by 25 per cent.The economic analysis clearly indicated that, net returns and B:C ratio at M1P75 was the highest (Rs.17250.00 per ha and 3.14 respectively) in maki7ng this production practice more profitable.
