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.

    SOURCE-SINK RELATIONSHIP AS INFLUENCED BY LATE LEAFSPOT IN GROUNDNUT GENOTYPES
    (UNIVERSITY OF AGRICULTURAL SCIENCES, DHARWAD, 1997) BHAT, TANMAI; M B, CHETTI
    In an attempt to findout the influence of late leafspot caused by Phaeoisariopsis personata on various morphological, physiological, biophysical, biochemical, histological, histopathological and histochemical parameters and partitioning efficiency, a field experiment was conducted during kharif 1996 at College of Agriculture Farm, University of Agricultural Sciences, Dharwad. The experiment consisted of six treatment combinations comprising three genotypes differing in disease reaction viz., susceptible (TMV-2), moderately resistant (Dh-74) and tolerant (ICGV-86590), raised under both protected and unprotected conditions in four replications. The plants in the unprotected treatments were sprayed with the inoculum of P. personata at 45 days after sowing (DAS) to induce the incidence of the disease.Results revealed that late leafspot caused a significant reduction in plant height, dry weight of leaf, stem, root and pods, growth parameters viz., LAI, LAR, LAD and BMD. The extent of reduction was more in unprotected treatments as compared to protected treatments in all the genotypes. Among the genotypes, there was least reduction in ICGV-86590 and maximum in TMV- 2. With respect to yield and yield components, oil content and shelling per cent, it was observed that there was a significant reduction due to disease incidence in the unprotected treatments and the extent of reduction was maximum in TMV-2 and minimum in Dh-74.Chlorophyll 'a', chlorophyll 'b', total chlorophyll and nitrate reductase activity reduced significantly due to disease incidence. The level of total sugars increased after infection and the extent of increase was maximum in TMV-2. Whereas, total phenols and tannins were significantly higher in protected treatments and in ICGV-86590. Leaf thickness was found to be more in TMV-2 than in ICGV-86590 but. the epidermal thickness and number of epidermal cells were more in ICGV- 86590 than in TMV-2. Polysaccharides. Proteins, and RNA contents were low in healthy leaves and petioles but were rich in disease affected plant parts. It is inferred that the incidence of late leafspot brings about considerable changes in plant morphology, physiology, histology, histopathology and histochemistry which altogether influence the source-sink relationship in groundnut.

    PHYSIOLOGICAL BASIS OF BIOLOGICAL AND CHEMICAL CONTROL OF EUPATORIUM (Chromolaena odorata K & R)
    (UNIVERSITY OF AGRICULTURAL SCIENCES, DHARWAD, 1997) Y PATIL, HOLALAGOUD; M B, CHETTI
    "Field experiments were conducted on the naturally grown Eupatorium at the Farm Forestry Department, University of Agricultural Sciences, Dharwad during 1995 and 1996 to find out the allelopathic effect of crop and weed extracts on growth, development and reproductive efficiency of Eupatorium and the effect of additives to increase the efficacy of herbicides. The first experiment consisted of twenty nine treatment combinations having leaf and root extracts of two crop species (Paddy and Sunflower) and five weed species (Lantana, Marigold, Cassia, Parthenium and Clerodendron) both at 5 and 10% concentrations. The treatments were imposed by preparing aqueous extracts of crop and weed extracts before the full bloom stage (approximately 90 days old seedlings). The second experiment consisted of thirteen treatment combinations comprising different concentrations of 2,4-D and Glyphosate (2000, 3000 and 4000 ppm) along with the additives urea, KN03 and Ammonium sulphate at 1 % concentration. The treatments were imposed at 60 days old plants.Results revealed that with an increase in the concentration of extracts, there was a decrease in photosynthetic rate, transpiration rate, chlorophyll content, sugar content, stomatal resistance, leaf temperature and relative water content. However, there was a significant increase in the total free phenols due to the application of extracts. It was further observed that the effect was more with leaf extracts than with the root extracts. Among different species, parthenium followed by clerodendron and lantana were more effective in bringing a desirable change for controlling growth and development of Eupatorium as compared to other crop and weed extracts.In the second experiment, relative water content was found to be least in Glyphosate in combination with Ammonium Sulphate and higher concentrations of Glyphosate and 2,4-D alone. Photosynthetic rate and stomatal conductance decreased with an increase in the concentration of herbicides with the combination of additives. Decrease in various biochemical parameters like chlorophyll a, chlorophyll b and total chlorophyll was noticed with an increase in the concentration of herbicides and in combination with additives. Among them, the extent of decrease was more in Glyphosate+Ammonium sulphate, 2,4-D + Ammonium sulphate and higher concentrations of Glyphosate and 2,4-D alone".
