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.

    INFLUENCE OF TEMPERATURE REGIMES ON MORPHO PHYSIOLOGICAL TRAITS ASSOCIATED WITH PRODUCTIVITY IN GROUNDNUT [Aracbls bypogaea L) GENOTYPES
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1999-08-30) PATIL, S. J.; CHETTI, M. B.
    Field experiments were conducted during rabi/rabi-Summer seasons of 1994-95 and 1995-96 to study the influence of temperature regimes on morphological, physiological, biochemical and yield components in groundnut genotypes at Regional Research Station, Raichur, Universit}-of Agricultii-al Sciences, Dharwad. The experiment consisted of four temperature regimes and ten genotypes laid out in factorial randomised block design with three replications. Results revealed significant differences between the genotypes, temperature regimes and their interaction widi respect to various morphological, physiological, growth and biochemical parameters. Number of branches per plant, drymatter accumulation and growth parameters except BMD decreased with an increase in the growth temperature. Crop took less number of days for initiation and cessation of flowering with an increase in the growth temperature. The genotype Dh-40 took the maximum number of days for flower initiation, while JL-24 took the least number of days. The number of flowers per plant reduced greatly with an advancement of growth temperatures. The genotype R-8808 produced the maximum number of flowers and TMV-2 produced the least number of flowers. The genotype R-8808 followed by ICGS-11 and R-9251 accumulated more dry matter while the genotypes TMV-2 and JL-24 recorded tlie least. The Chlorophyll content and NR activity increased upto 60 DAS and decreased thereafter irrespective of the temperature regimes and genotypes. The extent of declme was more in TMV-2 and Dh-40 and least in R-8808, R-9251 and R-9214 due to increase in growth temperatures. The wax content increased with an increase in growth temperature and advancement in crop growth with genotypes R-9214 followed by R-8808 and R-9251 having the maximum values. While toe genotypes Dh-8, Dh-40 and TMV-2 had the lower values. The pod yield, kemal weight, 100-seed weight shelling per cent and harvest index decreased with an increase in the growth temperature. The genotypes R-8808, R-9214 and R-9251 recorded the maximum pod weight in all the temperature regimes and the extent of reduction in various yield components due to increase in growth temperature was less in these genotypes. However, the extent of reduction was maximum in TMV-2 followed by Dh-40.

    PHYSIOLOGICAL BASIS OF VARIATION IN PRODUCTIVITY POTENTIAL OF CHILLI {Capsicum annuum L.) GENOTYPES
    (UNIVERSITY OF AGRICULTURAL SCIENCES, DHARWAD, 1997) C M, NAWALAGATTI; M B, CHETTI
    "Field experiments were conducted at College of Agriculture Farm, University of Agricultural Sciences, Dharwad during kharif 1990 and 1991 to findout the physiological basis of variation in productivity potential and the biochemical basis of murda syndrome complex in four varieties, six lines and two hybrids of chilli. Results revealed that, the morpho-physiological traits differed significantly among the lines, varieties and hybrids, with hybrids recording significantly higher dry weight of leaf, stem, reproductive parts and TDM and having significant positive correlation with yield and yield components. Similarly, the growth parameters viz., AGR, CGR, NAR, SLW, LWR, LAR, LAD and BMD also differed significantly among lines, varieties and hybrids and had significant positive correlation with yield and yield components, except NAR, LWR and LAR.Fruit yield, number of fruits per plant, per cent fruit set, HI,fruitgirth,100-fruit weight, number of seeds per fruit, 1000-seed weight indicated significant differences among the genotypes. The fruit yield and the yield components were significantly higher in hybrids as compared to lines and varieties. The dry fruit yield was found to have significant negative correlation with plant height, days to 50 per cent flowering and stalk length. The capsaicin content and total colouring matter were significantly higher in varieties. Whereas, the ascorbic acid and oleoresin contents were significantly higher in hybrids.The influence of murda syndrome complex resulted in a significant decrease of chlorophyll, total sugars, total phenols and fruit yield in all the varieties, lines and hybrids, but the extent of reduction was more in hybrids and less in GPC-69, GPC-80 among lines, and Jwala among the varieties. It is thus inferred from the present study that, the dry weight of reproductive parts, LAD, SLW, AGR, CGR, HI, number of fruits per plant, 100-fruit weight, number of seeds per fruit, 1000-seed weight, per cent fruit set and fruit girth are important growth and yield parameters for enhancing productivity potential in chilli".
