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 HUMIC ACID BASED LIQUID NUTRIENT FORMULATION ON SOIL BIOLOGICAL PROPERTIES, GROWTH AND YIELD OF PADDY (Oryza sativa L.), MAIZE (Zea mays L.) AND TOMATO (Lycopersicon esculentum Mill.) UNDER FIELD CONDITION
    (University of Agricultural Sciences, Bangalore, 2022-12-06) LAVANYA, S M; MUTHURAJU, R
    The present study was carried out to understand the effect of different humic acid basedliquid nutrient formulations and humic acid coated fertilizers on soil biological properties,growth and yield of paddy, maize and tomato under field condition. Application of the humicacid based liquid nutrient formulations i.e., Product 1 @ 2.0 l/acre stimulated significantlyhigher population of free-living nitrogen fixers in paddy (9.64×104 CFU/g), maize (9.69×104CFU/g) and tomato (9.99×104 CFU/g) rhizosphere. Further, highest dehydrogenase enzymeactivity in paddy (124.52 μg TPF/g/h), maize (126.07 μg TPF/g/h), tomato (151.25 μg TPF/g/h)and microbial biomass carbon and nitrogen in paddy (402.43 and 46.95 μg/g of soil), maize(455.26 and 53.11 μg/g of soil) and tomato (446.41 and 52.08 μg/g of soil) rhizosphere wasobserved in treatment that received the Product 1 @ 2.0 l/ac. Application of humic acid coatedfertilizer recorded increased plant height (128.19 cm), number of tillers (24.81/plant), numberof panicles per plant (19.38), grain yield (31.76 q/ha) in paddy, highest seed weight at harvest(124.94 g), grain yield (64.91 q/ha) in maize and highest plant growth parameters, highestnumber of fruits per plant(19.52), fruit weight per plant (8.70 kg) and fruit yield (66.13 q/ha) in tomato. It is evident from the data obtained in the field experiment involving paddy, maize andtomato that application of humic acid based liquid nutrient formulation product 1 @ 2.0 l/acreenhanced the biological properties of rhizosphere soils, growth and yield of these cropscompared to the soil which received inorganic fertilizers.

    INFLUENCE OF LACTIC ACID BACTERIAL INOCULATION ON ENHANCEMENT OF SHELF LIFE OF MINIMALLY PROCESSED CUT FRUITS AND VEGETABLES STORED IN ACTIVE BREATHABLE BAGS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-07-14) PRAGATHI NAG, H. N; Narayanaswami, B
    A study was conducted to investigate the influence of isolated Lactic Acid Bacterial (LAB) inoculation and modified atmosphere packaging using Active Breathable Bags (ARB) on post-harvest qualities of minimally processed cut fruits and vegetables like Pineapple, Pomegranate, Carrot and Cucumber, kept at 4 and 10ᴼ C. High permeabilities of ARB film to O2 (18 % v/v) and CO2 (< 1% v/v) significantly affected levels of modified atmosphere conditions in package headspaces. On the other hand LDPE (control) packaging maintained O2 (9 % v/v) and CO2 (8.2 % v/v). High levels of O2 in ARB bags apparently increased the rates of respiration resulting in spoilage, although there was less per cent spoilage in LDPE compared to ARB. Mean while treatment with ARB+LAB was on par with LDPE. Increased microbial load was observed in ARB bags. However, in ARB+LAB treated significantly reduced the total viable counts in storage. Whilst vitamin C and antioxidants of cut fruits and vegetables packed in ARB+LAB bags were higher than those in ARB. Evaluation of organoleptic characteristics scored good acceptability with respect to LDPE and ARB+LAB compared to ARB bags alone. This study suggests that Lactobacillus plantarum could be successfully applied during processing of fresh-cut fruits and vegetables, contributing as a bio-preservative agent inducing a protective effect against relevant food borne pathogens

    MICROBIAL CONTROL OF TOMATO FRUIT BORER, Helicoverpa armigera (Hubner) BY ENTOMOPATHOGENIC FUNGAL AGENTS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2009-07-10) PESAL, SAVITHA; SHIVAPRAKASH, M K
    The investigations on “Microbial control of tomato fruit borer, Helicoverpa armigera (Hubner) by entomopathogenic fungal agents” were carried out during 2008-2009 at the Bio-Control Research Laboratories (BCRL), Pest Control (India) Pvt. Ltd., located at Sriramanahalli, Doddaballapur road, Bangalore. Dose mortality response between Helicoverpa armigera and Beauveria bassiana, Metarhizium anisopliae, Nomuraea rileyi and Verticillium lecanii in the laboratory indicated that mortality of larvae increased with increase in concentration and exposure period. Younger larvae found to be more susceptible to fungal species than older ones. N. rileyi (Nr1) proved superior to B. bassiana (Bb1, Bb2, Bb3) and M. anisopliae (Ma1, Ma2, Ma3). Whereas, V. lecanii (Vl1, Vl2, Vl3) failed to cause disease in H. armigera larvae. N. rileyi (Nr1) was used for further studies. Among the storage conditions, Nomuraea rileyi conidia in wettable powder formulation and oil based formulation recorded highest per cent germination in refrigerated conditions (40C) than at room temperature (27OC). The wettable powder formulation of Nomuraea rileyi viz., Bentonite + glucose (7:1) and Bentonite recorded 71 and 69 per cent mortality, respectively and the oil based formulations viz., sunflower oil, sesame oil and ground nut oil recorded 82, 77 and 77 per cent mortality respectively against 3rd instar larvae of H. armigera under laboratory conditions. In the field experiment, Nomuraea rileyi in sunflower oil formulation (15.43 t/ac) and Bentonite formulation (14.83 t/ac) were proved better. Significantly higher yield was noticed in chemical control (17.28 t/ac).
