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.

    POTASSIUM DYNAMICS IN SOILS UNDER COTTON BASED CROPPING SYSTEM OF NORTH KARNATAKA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1999-08-30) HIREKURABAR, B. M.; Satyanarayana, Dr. T.
    Seventy two soil samples from eigtJiteen prollles belonging to order Vertisol under cotton based cropping system of Nortli Kamataka were collected to investigate distribution of forms of potassium, K content in soil textural fractions, K fixation and release characteristics and Quantity-Intensity ( Q/1 ) parameters of potassium in these soils. The range in contents of various forms of potassium in the soil profiles were 8.00 to 20.25 ppm, 102 to 285 ppm, 445 to 1125 ppm, 0.454 to 1.328 per cent, 0.523 to 1.460 per cent and 306 to 770 kg K2O ha-1 of water soluble, exchangeable, non-exchangeable, lattice, total and available potassium, respectively. The average contribution of water soluble, exchangeable,nonexchangeable and lattice K to total soil K varied from 0.09 to 0.30, 1.21 to 3.33, 5.97 to 11.90 and 85.00 to 92.30 per cent, respectively. The potassium content in coarse sand, fine sand, silt and clay ranged from 0.15 to 0.42 , 0.32 to 1.19, 0.46 to 1.33 and 0.63 to 1.65 per cent, respectively. The mean potassium contribution from coarse sand, fine sand, silt and clay towards total soil K were 3.85,5.36,22.86 and 67.93 per cent, respectively. The K fixation capacity of surface soils varied from 0.78 to 1.34 c.mol (p t-)kg-1. The per cent K fixation varied from 15.60 to 27.20. The cumulative K release, step-K and constant rate K values ranged from 537 to 1157, 400 to 747 and 13 to 44 ppm, respectively. The Q/I parameters viz.,AReK ,Kl ,Kx, Kq ,PBCK and - G values ranged from 1.45 to 3.10(ML-1) 10-3 0.80 to 1.30, 0.50 to 0.76, 0.30 to 0.54 c.mol (p+) kg-1/ ( ML -1 ) and 3421 to 3871 cal. respectively. The soils under present study were high in available and step-K. However, the crops may face deficiency of potassium due to lower immediately available K( AReK ). Hence, K fertilization is necessary to available K to cotton crop

    STUDIES ON POTASSIUM DYNAMICS IN RICE SOILS OF DIFFERENT AGRO-CLIMATIC ZONES OF KARNATAKA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1999-08-30) GALI, S.K.; Satyanarayana, Dr. T.
    An investigation was earned out to study the potassium dynaimics in rice soils of diSerent agro-climatic zones of Kamataka, The soils used in the study varied widely in then- characteristics.The water soluble, exchangeable and non-exchangeable K contents of soils varied from 2 to 7, 31 to 232 and 60 to 982 ppm, respectively. While, lattice and total K contenu varied from 0.297 to 2.818 and 0.306 to 2.876 per cent, respectively. On an average, water soluble, exchangeable, non-exchangeable and lattice K constituted O.OZ 1.02 and 96.02 per cent of total K. Coarse sand and fine sand fractions were the dominant contributors to total K in coarse textured soils while, silt and clay were the major contributors to total K in fine textured soils. The cold H2SO4 extractabie K was found to be a better availability index for these soils . The higher K releasing power was noticed in soils of Belgaum, BhadravatlHiriyur and Kathalgere. The soils of hilly and coastal zones exhibited poor K releasing power. The smectitic black soils showed higher K supplying power than kaolinitic red and laieritic soils and a distinct difference between K releasing power and K supplying power of soils was brought out in this study. Green house studies indicated that the kaolinitic soils, particularly, soils of hilly and coastal zones would respond well to application of K at higher level (50 ppm) whereas, the smectitic black soils may need only maintenance dose (25 ppm) of potash fertilizer.The potassium fixation capacity of soils raided from 0.16 to 1.53 c mol (p+ kg -1 the black soils showing higher fixation capacity than red and lateritic soils. EEtc, the K bearing mineral was present as an associated clay mineral in all the soils except in soils of Bhadravati and Hiriyur where, it occurred as co-dominant mineral along with Kaolinite.
