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.

    RESPONSE OF CORN TO DIFFERENT SEQUENCE OF WATER STRESS AS MEASURED BY EVAPOTRANSPIRATION DEFICITS
    (UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 1963) MIRSRA, RAM DEO; HAGAN, ROBERT M; HENDERSON, DELBERT W; PRUITT, WILLIAM O
    Increased demands by engineer and economist for informs ion pertaining to agricultural production with different levels of water supply call for intensified efforts to develop crop water production functions. Their importance is increasingly recognized, especially in water project planning, water allocation and delivery and in farm irrigation planning, design and operations. Improvements in the accuracy of such estimates increase the usefulness of the planning process. Functional relationships between crop yield and water supply presently available are only roughly estimated and are either assumed or derived empirically. This may be one of the reasons why present irrigation practices are not much different from those of the past in spite of the tremendous amount of work reported in relevant literature. This is not to imply that past work has not been important; in fact, work done in the past has helped to formulate present experimentation. Recently, however, the need for better predictive capability has become much greater, due to population expansion, intense competition for water between agricultural and nonagricultural needs, and increasing scarcity of natural water resources. Finally, but not least, environmentalists are bringing pressure on agriculturalists to use water more judiciously and wisely than in the past. This situation requires sound planning and management of irrigation.

    A TECHNIQUE FOR CONTROLLING SOIL WATER CONTENT IN THE VICINITY OF ROOT HAIRS AND ITS APPLICATION TO SOIL-WATER-PLANT STUDIES
    (UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 1963) HSIEH, JACK JUI-CHANG; GARDNER, W H
    A technique for controlling water content in the root hair zone of growing plants has been developed and used to investigate (1) the relationship between soil water tension and plant growth and (2) the nature of water flow in the vicinity of root hairs . This technique could also be adapted to study the extent of mobilization of various plant nutrients and herbicides into the root hair zone and their subsequent uptake. The technique involves growing plants on a fine screen placed over soil in such a way that root hairs extend about 1.5 mm through the screen into soil with both main roots and rootlets remaining above the screen. A gamma-ray moisture detecting device is used to monitor the supply of water in the root hair zone • . By paeans of either adjusting the length of a hanging water column or controlling the rate of water supply. the rate of water flow to the soil lamina beneath the screen can be so adjusted as just to offset the loss due to evapotranspiration . Therefore. a predetermined soil water level can be maintained to within ~1.5\ water content in the root hair zone a growing plant. The expert~~~entail data show the dependence of plant growth upon Soil -~•r tension. lbe &Roth of corn leaves vas first affected by water -tension at 1 bar or less. Growth ceased at about 22-30 bars tension within the root b£ir ~. lbe soil laaina just outside the root hair zone had only about b&l.f ~he water ~end ion of t ha.t inside the zone.

    EFFECTS OF AMENDMENTS, DRAINAGE AND RICE GROWTH ON SODIC SOIL RECLAMATION
    (UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 1972) PUTTASWAMY GOWDA, BYADARAHALLY SIDDEGOWDA; PRATT, P F
    The effects of straw and CaCl2 during 130 days of submergence, and effects of these amendments under submerged aerobic vs anaerobic conditions for a period of 30 days were studied by comparing the pH, EC, Na, Ca + Mg, K, Fe, the optical density of the water extract and the ESP. The straw and straw + CaCl2 treatments had the largest effect in lowering the pH and ESP, increasing the Na and Ca + Mg and the EC, Submerged anaerobic conditions had the largest effect on promoting these reactions. The concentration of Fe was highest in the straw treatments whereas CaCl2 had a depressing effect on the soluble Fe++ The optical density of water extracts was lowest in the straw + CaCl2 treated soil and the effect of this treatment was larger under anaerobia conditions. Wheat straw under anaerobic conditions caused an increase in the sum of Na + Ca + Mg in the soil solution that was about three times greater than the sum of these cations in the straw itself. In combination with CaCl2 wheat straw reduced the loss of Ca from solution. The mechanisms involved in the process of reclamation of a sodic soil under submerged condition while using straw or organic manures as amendments seems to be (a) decomposition of organic matter, release of salts and evolution of CO2 and certain organic acids, (b) lowering of pH and release of cations by solubilization of CaCO2 and other soil minerals thus increasing the EC, (c) replacement of exchangeable Na by Ca and Mg and lowering of the ESP. Submerged anaerobic conditions were found to be optimum for this process. In a greenhouse pot-culture study, effect of organic amendments on the reclamation of a saline sodic soil material under submerged conditions were studied with and without presence of a rice crop. In drained soils, application of dairy manure, sugar, straw or straw plus CaCl2 increased the rate of drainage, and decreased the EC and ESP. Without drainage, treatments were less effective. Crop growth hastened the reclamation process by increasing the volume of water drained and the concentration of Ca + Mg in the drainage water. Drainage had a significant effect in increasing the vegetative growth of rice, percentage of ear-bearing tillers, straw and grain yield. In the undrained condition, organic soil amendments, except dairy manure, adversely affected the straw and grain yield, and sugar severely affected the establishment of transplanted seedlings.
