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.

    EFFECT OF CONJUNCTIVE USE OF UNDERGROUND AND SURFACE WATER ON SOIL PROPERTIES, NUTRIENT UPTAKE AND YIELD OF WHEAT IN GHATAPRABHA COMMAND AREA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1998-08-19) HUNDEKAR, SANATKUMAR T.; Sarangamath, Dr.P.A.
    An investigation was undertaken to study the seasonal underground water quality and water table fluctuations in Raibag and Chikodi taluks (Belgaum district) of Ghataprabha command. Further during rabi seasons of 1995-96 and 1996-97, field experiments were carriedout in a farmers field at Alaknur village (Raibag taluk) to study the various modes of conjunctive use of underground and canal waters on soil properties, growth and yield of wheat. The analysis of underground waters revealed a shift from high salt concentration in summer to lower levels in rainy season. Winter samples exhibiting intermediate properties. Majority of the samples regardless of season, belonged to C3S1 and C3S2 classes. Among the twelve irrigation treatments adopted, namely T1 to T5 (one to five canal irrigations followed by groundwater supplementation), T6 (canal water alone), T7 (groundwater alone) and T8 to T12 (cyclic modes of canal and groundwater usage). T7 exerted deleterious effects on soil physical properties besides increasing in soil pH and electrical conductivity and reduction in availability of primary nutrients, and their reduced uptake and reductions in various agronomic growth and yield parameters. On the contrary, T6 was the best of the treatments in respect of both soil properties and crop growth and yield. The treatments in receipt of four or five canal water irrigations followed by groundwater supplementation (T4 and T5) under direct mode and those with the use of these two waters at the ratios of 1;1 or 2:1 under cyclic pattern of conjunctive usage, however, were found to be statistically not differing from the best of the treatments (T6). With respect to germination on the other hand, initial irrigation with groundwater was found harmful. Thus, it is concluded from the investigations that the conjunctive pattern in the manner as said above can be adopted without much harmful effect on soil properties and yield of wheat during the periods of canal water shortages.

    STUDIES ON CHEMISTRY OF POTASSIUM IN SUGARCANE SOILS OF NORTH KARNATAKA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1998-08-19) HEBSUR, N.S.; Satyanarayana, Dr. T.
    Ten soil pedons belonging to orders viz., Vertisol, Inceptisol and Alfisol derived from diverse parent materials from major sugarcane growing areas of North Karnataka were considered to study distribution of different forms of potassiium, K content In various textural fractions, its fixation and release parameters like cumulative K, CR-K and step-K, mineralogy of clay and transformation of added K In these soils. The range in contents of various forms of K in soil samples was 0.025 to 0.620 me of water soluble, 0.35 to 1.10 c mol (p+) kg-1 of exchangable, 150 to 1250 ppm of non-exchangeable, 0.47 to 3.25 per cent of lattice and 0.53 to 3.70 per cent of total potassium. Available K ranged from 275 to 900 kg ha-1. The water soluble, exchangeable, non-exchangeable and lattice potassium constituted 0.02 to 0.21, 0.64 to 4.01, 0.87 to 10.9 and 86.0 to 98.4 per cent of total K, respectively. Potassium contents in soil textural fractions viz., coarse sand, fine sand, silt and clay were in the range of 0.23 to 2.72, 0.40 to 3.23, 0.15 to 9.85 and 0.48 to 2.80 per cent, respectively in different profiles. The semi-quantitative estimate revealed the dominance of smectite in the clays of black soils and kaolinite in the clays of mixed black and red and red soils with associated minerals like mica, chlorite, kaolinite and vermiculite. The K fixation of surface soils ranged from 0.39 to 1.32 c mol (p+) kg-1. In transformation studies, water soluble K content increased in all soils with increasing levels of added K and decreased with time of Incubation. On the other hand, exchangeable K Increased with time of incubation. The added K @ 1.25 and 2.50 c mol (p+) kg-1 reacted to the tune of 223.0 to 458.7 and 448.0 to 931.2 ppm, respectively in different soils after 60 days of incubation. The cumulative K release, step-K and constant rate K values ranged from 378 tol 175, 306 to 770 and 8 to 45 ppm, respectively. Considering these parameters, the soils under study may not respond to the application of potassic fertilizers.

    STUDIES ON COPPER IN RED AND LATERITIC SOILS AND EFFECT OF COPPER ORE WASTE AND COPPER SULPHATE ON GROUNDNUT {Arachis hypogaea L.) IN RED SOILS OF NORTH KARNATAKA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1998-08-19) GUNDLUR, S. S.; MANJUNATHAIAH, Dr.H.M.
    Studies made on forms and distribution of copper in red and lateritic soils of North Karnataka indicates that the total and available copper content of red soils was in the range from 37.0 to 83.0 and 0.29 to 3.38 ppm,where as in lateritic soils the range was from 35.0 to 54.0 and 0.29 to 4.30 ppm respectively. The pH and organic matter contents of soil are found to influence the total and available Cu content of soil. The magnitude of different fractions of Cu in both the soil types are found to be followed the order, residual copper > organically bound copper > occluded copper >inorganically bound copper > water soluble and exchangeable copper. Field experiments were conducted on red soils at Manoli, Hanumanamatti and Kulageri during summer 1995 and 1996 under irrigated condition, to study the response of groundnut {TMV-2) to copper sulphate and copper ore tailings (GOT). Application of COT and CuSO4 (at different levels respectively) significantly increased the concentration and uptake of all the nutrients except Ca++ and Mg++. Pooled data of two years of all three locations indicated that application of CuSo4 @ 30 kg/ha significantly increased the groundnut pod yield (21.14 q/ha),haulm yield (27.71 q/ha) and oil yield (6.50 q/ha). Similarly application of COT @ lOOQ kg/ha produced highest groundnut pod yield (2-1.Oa q/ha), haulm yield (29.95 q/ha) and oil yield (7.5G q/ha). Between CuSO4 and COT treatments the pod yield, haulm yield and oil yield were superior with application of COT over CuSO4 application. This is due to combined effect of 2n, Fe, Cu and sulphur present in the COT, Further, the COT left over considerable amount of residual Zn, Cu, Fe and S which will enhance the soil fertility level and useful for succeeding crop.
