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 VITAMIN B12 (CYANOCOBALAMIN) PRIMING ON ALLEVIATING SALINITY STRESS IN CHICKPEA (Cicer arietinum L.)
    (University of Agricultural Sciences, Bangalore, 2018-07-01) MANJUNATHA, R.; DAYAL DOSS, D.
    Chickpea (Cicer arietinum L.) is sensitive to salinity. The present investigation was carried out to evaluate the effects of saline water and vitamin B12 (Cyanocobalamin) priming on growth parameters and biochemical attributes in chickpea genotypes HC-5 (salt sensitive) and JG-11 (salt tolerant). The seeds were primed in various concentrations of vitamin B12 (10 and 20 μM). Physiological characters (Plant height, number of leaves, dry weight, and relative water content) and biochemical (antioxidants, malondialdehyde, proline, protein) parameters were analyzed. Results revealed an increase in growth parameters such as plant height, number of leaves, root and shoot dry weight, leaf area and nodule number. Salinity stress caused a decline in yield and yield attributes in HC-5 genotype. At the biochemical level, higher accumulation of osmotic solute proline and lipid peroxidation were observed. An increase in the activity of Superoxide dismutase, Peroxidase and Catalase and increased leghaemoglobin content were also observed in tolerant genotype (JG-11) as compared to sensitive genotype. Seed priming with vitamin B12 induced these stimulatory effects on all the measured parameters. The relative expression of CMO and BADH gene was higher in JG-11 indicating increase in synthesis of glycine betaine in tolerant variety. SDS-PAGE revealed more deletion than addition of polypeptide bands and increase/decrease in the intensities of certain bands was noticed in the seeds of JG-11 and HC-5. Results evinced that Vitamin B12 priming of seeds can be effectively used as a pre-sowing treatment for mitigating adverse effects of salinity in chickpea genotypes.

    EFFECT OF DIFFERENT COMBINATIONS OF ORGANIC NUTRIENT SOURCES ON GROWTH AND YIELD OF MAIZE (Zea mays L.) UNDER CAUVERY COMMAND AREA
    (University of Agricultural Sciences GKVK, Bangalore, 2010-07-03) MANJUNATHA, R.; SUBBARAYAPPA, C. T.
    A field experiment entitled “Effect of different combinations of organic nutrient sources on growth and yield of maize (zea mays L.) under cauvery command area” was conducted at Zonal Agriculture Research Station, V.C. Farm Mandya, during kharif season of 2009-10 on sandy loamy soil to study the effect of different combinations of organic nutrient sources on growth and yield of maize, soil properties, uptake of NPK in maize and to compute B: C ratio. The treatment consists of FYM, poultry manure, vermicompost, press mud equivalent to FYM (N) in combination of biodigester liquid and cattle urine equivalent to 150 kg N compared with recommended dose of FYM+NPK. The experiment was laid out in a randomized complete block design with nine treatments replicated thrice. significantly higher plant height (187.17cm), number of leaves per plant (13.32), grain yield (61.84 q ha-1) and stover yield (111.31 q ha-1) was recorded in the treatment combinations of recommended dose of FYM 10 t ha-1 + NPK 150: 75: 40 kg ha-1 N and it was on par with the treatment combinations of poultry manure equivalent to FYM (N) + biodigester liquid equivalent to 150 kg N. The soil properties viz., Bulk density , particle density, maximum water holding capacity, pH, EC, OC, major nutrients, secondary nutrients and micronutrients (Zn,Fe,Mn &Cu) was not differed significantly due to different combinations of organic nutrient sources. Significantly higher total nutrient uptake of N, P and K (194.17, 50.70 and 223.60 kg ha-1 respectively) were recorded in the treatment receiving FYM 10 t ha-1 + NPK 150: 75: 40 kg ha-1 N. Higher B: C ratio (3.15) was recorded in the treatment combination of poultry manure equivalent to FYM (N) + biodigester liquid equivalent to 150 kg N followed by the treatment combinations of FYM 10 t ha-1, recommended NPK 150: 75: 40 kg ha-1 N (3.08).

    EFFECT OF MICROBIAL INOCULANTS ON GROWTH OF JATROPHA AND PONGAMIA-BIOFUEL PLANTS
    (University of Agricultural Sciences, Bangalore, 2008-08-15) MANJUNATHA, R.; MALLESHA, B. C.
    Studies were carried out to evaluate the effect of microbial inoculants on growth of Jatropha and Pongamia – biofuel plants. General microflora and beneficial microflora like P-solubilizers and free living N2 fixing population in the rhizosphere of biofuel plants was enumerated. Bacteria were found to be highest in population compared to fungi and actinomycetes in rhizosphere. Bacteria were found to be highest in Neem rhizosphere where as fungi and actinomycetes in Hippe rhizosphere. N2 fixers and P solubilizers were highest in Neem rhizosphere. In general bacteria were highest in population followed by fungi and actinomycetes. P-solubilizing bacteria and free living N2-fixing bacteria were isolated from rhizosphere of biofuel plants. These isolates were screened for P-solubilization and N2 -fixation under in vitro condition, PSB6 isolate was found to be efficient Psolubilizer and NF3 isolate was found to be efficient N2 fixer. Effect of inoculating free living N2 fixer and P-solubilizers on the growth parameters of Jatropha and Pongamia seedlings was studied under greenhouse condition. Highest growth was observed in treatment Bacillus megaterium with rock phosphate followed by in PSB6 isolate with rock phosphate. Nitrogen content in shoot and root was maximum in seedlings inoculated with Azotobacter chroococcum and rock phosphate. Inoculation with P-solubilizers and free living N2 fixers to biofuel plants improved plant growth.
