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.

    EFFECT OF PHOSPHORUS ENRICHED BIOCOMPOST ON SOIL PROPERTIES, GROWTH AND YIELD OF FINGER MILLET (Eleusine coracana G.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2019-08-05) LAVANYA, G.
    A field experiment entitled “Effect of phosphorus enriched biocompost on soil properties, growth and yield of Finger millet (Eleusine coracana G.)” was conducted during kharif 2018 at Shri Chamundeswari Sugars Ltd., Bharathi Nagar, Maddur (Tq), Mandya (D). The experiment was laid out in randomised complete block design with nine treatments and three replications. The experimental results revealed that application of 100 % NPK + RP-PSB enriched biocompost @ 10 t ha-1 significantly increased the plant height (93.42 and 118.2 cm at 60 DAT and harvest, respectively), number of tillers per plant (3.76, 3.85 at 60 DAT and harvest, respectively), number of fingers per ear head (9.17), test weight (3.45 gm), grain yield (3752 kg ha-1) and straw yield (6386 kg ha-1). Significantly higher amount of soil major nutrients like N (321.56 and 279.30 kg ha-1 at 60 DAT and harvest, respectively), P2O5 (235.68 and 204.35 kg ha-1 at 60 DAT and harvest, respectively) and K2O (426.50 and 418.12 kg ha-1 at 60 DAT and harvest, respectively) was recorded with the application of 100 % NPK + RP-PSB enriched biocompost @ 10 t ha-1. Significantly higher grain and straw uptake of major nutrients like N (44.28 kg ha-1 and 47.25 kg ha-1 respectively), P (15.38 kg ha-1 and 19.16 kg ha-1 respectively) and K (19.51 kg ha-1 and 52.36 kg ha-1 respectively) was recorded with the application of 100 % NPK + RP-PSB enriched biocompost @ 10 t ha-1. The economics of crop production also indicated the benefit of enrichment of biocompost and hence it may be followed to enhance crop productivity in farmer's field.

    FORMULATION AND EFFECTIVENESS OF FLUID BED DRIED CONSORTIA OF AGRICULTURALLY BENEFICIAL MICROORGANISMS
    (University of Agricultural Sciences GKVK, Bangalore, 2014-09-10) LAVANYA, G.; Brahmaprakash, G. P.
    This study focused on formulation development using suitable carrier material in a fluid bed dryer (FBD) of different agriculturally beneficial microorganisms, survival of these inoculant formulation prepared in fluid bed dryer at different intervals and effectiveness of these inoculant formulation on cow pea (Vigna unguiculata L.) and finger millet (Eleusine coracana Gaertn.) crop. Among different carriers (flyash, talc and skim milk powder) tried in different combinations, formulation prepared usig a combination of talc and skim milk powder at 40° C in FBD resulted in better survivability of microbial population. The two consortia using Rhizobium sp., Bacillus megaterium and Pseudomonas fluorescens and another consortia of Acinetobacter sp., Bacillus subtilis and Azotobacter chroococcum was prepared using talc and skim milk powder in a fluid bed dryer. The survival of these two consortia was monitored during 360 and 365 days of storage period respectively where in the triple inoculant formulation prepared using FBD resulted in maximum cell survival till the end of storage period. No contamination was observed in all FBD inoculant formulation at the end of 180 days at 10-5 dilution. Effectiveness of Rhizobium sp., Bacillus megaterium and Pseudomonas fluorescens on cowpea; Acinetobacter sp., Bacillus subtilis and Azotobacter chroococcum on finger millet crop was carried out in green house conditions at two nutrient levels with lignite based formulation as control. It was observed that both cowpea and finger millet plants inoculated with fluid bed dried triple inoculant formulation of both consortia under the influence of nutrients showed better plant growth parameters, higher nitrogen and phosphorus uptake followed by dual and single inoculants when compared to lignite based formulations.

    PHYTOCHEMICAL SCREENING AND ANTIMICROBIAL ACTIVITY OF COMPOUNDS FROM SELECTED MEDICINAL AND AROMATIC PLANTS
    (University of Agricultural Sciences, Bangalore, 2010-07-10) LAVANYA, G.; BRAHMAPRAKASH, G. P.
    The present study focused on developing a protocol, separation of compounds by chromatographic technique and screening antimicrobial compounds from selected medicinal and aromatic plants. Antimicrobial compounds from two medicinal (Lantana camara and Chromolaena odorata) and two aromatic (Pogostemon patchouli and Rosmarinus officinalis) plants were screened for their antimicrobial activity against four bacteria (Escherichia coli, Staphylococcus aureus, Xanthomonas campestris and Erwinia sp.) and two test fungi (Candida albicans and Fusarium oxysporum). Plants were extracted with different polar (ethanol and ether) and non-polar (chloroform and hexane) solvents. TLC profiling of all the plant extracts in different solvent system indicated the presence of different groups of phytochemicals in these plants. Terpenes, phenolic acids and flavonoids were found to be present in the biomass extracts of the plants used and the Rf values ranged between 0.3 to 0.95 for these compounds. Terpenes, phenolic acids and flavonoid compounds were effective in inhibiting the growth of microorganisms. Flavonoids from Lantana camara (Lantana) of ethanol extract were highly active against Fusarium oxysporum and phenolic acid group of compounds from chloroform extract of Rosmarinus officinalis (Rosemary) highly inhibited Xanthomonas campestris. Compounds from plant extracts showed highest activity against plant pathogens tested. Ethanol solvent was found to be better solvent for purifying the compounds followed by the solvent chloroform and ether. Hexane solvent was found ineffective in dissolving and separation of compounds.
