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.

    STUDY OF GROWTH AND TECHNOLOGICAL CHANGE IN MAJOR PULSES OF KARNATAKA
    (University of Agricultural Sciences, Bangalore, 2018-04-01) MAHESH; Gowda, D.M.
    A study has been made on growth and technological changes in major pulses of Karnataka. For this study 30 years (1984-2014) of secondary data on area, production and productivity of major pulses viz. Red gram, Bengal gram, Horse gram and Black gram has been collected from the DES, Bangalore. Linear and exponential models were fitted to know the linear and compound growth rate of major pulses separately for period I (1984-1999), Period II (2000-2014) and for combined period. The results of combined period indicated positively significant growth rate in area, production and productivity of Bengal gram, while Horse gram shows negative growth rate. Black gram shows nonsignificant growth rate in production and negative growth rate for area. No significant growth rate was noticed in period I. During period II the yield of Bengal gram per unit area had increased by 40 per cent. Black gram showed a decrease in yield by 34 per cent. In order to show the nature of trend quadratic model was the best fit, among linear, quadratic and cubic models. Based on adjusted R2 and RMSE. An attempt was made to study the technological change in production of pulses in Karnataka through Cobb- Douglas production function for period I, period II and for combined period. Technological change is determined by significant structural break, through Chow test. The study indicated that no technological changes in major pulse production. This suggests that there is a need to improve the production technology for Pulses in Karnataka State.

    INFLUENCE OF DIVERSE ORGANIC SOURCES ON GROWTH AND YIELD OF SUNFLOWER (Helianthus annuus L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK, BENGALURU, 2019-08-16) MAHESH
    A field experiment was conducted at Zonal Agricultural Research Station, UAS, GKVK, Bengaluru, during kharif 2018 to study the influence of diverse organic sources on growth and yield of sunflower. The experiment was laid out in a RCBD design with eight treatments replicated thrice. Application of Farm Yard Manure (FYM) on N eq. ha-1 + Bio Digester Liquid Manure (BDLM) on N eq. ha-1 + jeevamrutha at 1500 l ha-1 + panchagavya spray (7.5 %) recorded significantly higher seed yield (2195 kg ha-1) and oil yield (872 kg ha-1) and it was on par with application of FYM on N eq. ha-1 + jeevamrutha at 1500 l ha-1 + panchagavya spray (7.5 %) (1996 kg ha-1). The same treatments showed similar trend with respect to growth and yield parameters and also nutrient uptake by the crop (nitrogen, phosphorus, potassium). Soil fertility status improved with higher available nitrogen, phosphorus and potassium (389, 43.32 and 273 kg ha-1, respectively). Significantly higher bacteria, fungi, actinomycetes, N-fixers, P-solubilizers population and dehydrogenase activity were recorded in soil with application of FYM on N eq. ha-1 + BDLM on N eq. ha1 + jeevamrutha at 1500 l ha-1 + panchagavya spray (7.5 %). Higher net returns ( 43,468 ha-1) and B:C (2.08) ratio were recorded with application of FYM on N eq. ha-1 + BDLM on N eq. ha-1 + jeevamrutha at 1500 l ha-1 + panchagavya spray (7.5 %).

    GENETIC VARIABILITY FOR PHYTIC ACID IN FINGER MILLET (Eluesine coracana (L.) Gaertn.) GENOTYPES: MOLECULAR CHARACTERIZATION OF CONTRAST TYPES AND DEVELOPMENT OF Ipa MUTANTS
    (University of Agricultural Sciences GKVK, Bangalore, 2008-08-28) MAHESH; Shankar, A. G.
    Micronutrients are required in small quantities but play a vital role in various processes of human body. The intake of nutrients in daily diet is far from satisfactory and largely less than 50 % RDA (recommended Daily Allowance) is consumed by Indian population. Unavailability of the essential and vital micronutrients in plant based food may be due to either low content of nutrients or presence of anti-nutritional factor (ANF). One among the ANFs the phytic acid presents in all cereals, pulses and oil seeds. Phytic acid chelates cations like Zn2+, Fe2+, Ca2+ and Mn2+, makes them unavailable form. In this context made an attempt to develop mutant for low phytic acid line in leading variety. Chemical mutagen, 2 % (v/v) EMS was showed LD50 in GPU-45 variety. The mean phytic acid content in M| seeds ranged from 190.2 to 210.7 mg per lOOg of seed. In wild plants the mean phytic acid content was 202.1 mg per lOOg was observed. In this study the 530 core germplasm lines of finger millet were assessed for their phytic acid content in grains. There is a huge variation in phytic acid content and it ranges from 60.2 to 517.7 mg per lOOg. The 20 contrasting genotypes for phytic acid were analysed for zinc and iron content. Study showed distinct pattern of correlation with phytic acid. Zinc showed high significant correlation with phytic acid and high significant negative correlation was observed with phosphorus. Iron was not correlated with the phytic acid and inorganic phosphorus. All the four characters, zinc, iron, phytic acid and phosphorus are showed a good correlation between GCV and PCV and all are highly heritable. The SSR two rice markers RM 3542 and RM 482 were did not show polymorphism between low and high phytic acid types of finger millet.
