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.

ThesisItem Open Access NDIRECT REGENERATION OF Japonica RICE (Oryza sativa L. spp. japonica) VARIETIES AZUCENA AND MOROBEREKAN THROUGH ANTHER CULTURE(UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK BENGALURU, 2015-12-01) AVINASH SHARMA; Ashok, T. H.Rice (Oryza sativa L.) is one of the most important food crops of Southeast Asia, which feeds half of the world population. Anther culture is an efficient and convenient technique for rapid production of doubled haploids which are useful in crop breeding programs. Present study involved evaluation of two japonica rice varieties Azucena and Moroberekan cultured on 17 callus induction treatments on N6 medium and 19 regeneration treatments on MS medium. Highest callus induction frequency was observed in Azucena in treatment T4 (2, 4-D 2 mg L-1 + Kinetin 1 mg L-1 ) (49.99 %) followed by Moroberekan in treatment T11 (2, 4-D 1 mg L-1 + NAA 2 mg L-1 + Kinetin 0.5 mg L-1 ) (48.64 %). Highest shoot regeneration frequency was recorded in Azucena in treatment T10 (Kinetin 0.5 mg L-1 + BAP 2 mg L-1 + NAA 1 mg L-1 ) (83.33 %) followed by Moroberekan in treatment T16 (Kinetin 2 mg L-1 + BAP 1 mg L-1 + NAA 1 mg L-1 ) (80.0 %). Plantlet regeneration did not occur in Azucena. Highest plantlet regeneration frequency was recorded in Moroberekan in treatment T16 (Kinetin 2 mg L-1 + BAP 1 mg L -1 + NAA 1 mg L-1 ) (80.0 %) followed by in treatment T10 (Kinetin 0.5 mg L-1 + BAP 2 mg L-1 + NAA 1 mg L-1 ) (55.55 %). These results suggest that growth regulators and their concentration, along with genotype have significant effect on callus induction and regeneration from anthers in rice.ThesisItem Open Access IMPACT OF CROP ROTATION ON SOIL FAUNA IN ORGANIC FARMING ECOSYSTEM(University of Agricultural Sciences GKVK, Banglore, 2014-07-02) GOLIVE PRASANTHI; N. G. KUMARThe investigation on the impact of crop rotation on soil fauna in organic farming ecosystem was carried out at the ZARS, University of Agricultural Sciences, GKVK, Bangalore, during 2013. Soil application of 20 tonnes of FYM/ha+introduction of native fauna recorded significantly higher soil mesofauna, soil total Acari, cryptostigmatids, other Acari, other invertebrates and macro fauna like ants and beetles compared to other treatments during the cropping season. The highest population of total soil mesofauna was noticed 105 days after germination. Application of 20t of FYM ha"' significantly increased the soil organic carbon content(0.82%), available phosphorous(68.80 Kg/ha), available potassium(314.36 Kg/ha), exchangeable calcium(6.58 meq/lOOg), exchangeable magnesium(3.58 meq/lOOg), microbial biomass carbon(l 10.90 pg /g), microbial biomass nitrogen(10.87 pg /g), Dehydrogenase (296.37pg TPF/ g soil). Acid phosphatase (32.57pg PNP/ g soil). Alkaline phosphatase (15.77pg PNP/ g soil) and urease(l 11.54pg NH4"'/ g soil) in the soil compared to recommended fertilizer alone treatment. The same treatment also recorded higher plant biomass, root biomass, Rhizobium nodulation and grain yield(16.01 q/ha) compared to recommended package practices (12.90 q/ha) and recommended fertilizer alone(11.48 q/ha). Soil mesofauna abundance recorded a significant positive relationship with available phosphorus, exchangeable calcium, exchangeable magnesium, soil pH, microbial biomass carbon, Dehydrogenase and urease. Abundance of mesofauna played an important role in the formation of available phosphorus, potassium. Ex calcium. Ex magnesium and alkaline phosphatase. Soil moisture and atmospheric minimum temperature showed significantly positive and negative relationship with the abundance of soil mesofauna. These factors together with rainfall exhibited significant influence on the abundance on the mesofauna(67%).ThesisItem Open Access BIOCHEMICAL STUDIES ON RICE {Oryza sativa L.) CULTIVARS FOR NUTRITIONAL EVALUATION(University of Agricultural Sciences GKVK, Banglore, 2013-03-05) R. DRUVASHREE; R. CHANDRURice cultivation is improving in India with the release of number of varieties and hybrids. An investigation was undertaken to evaluate the physico chemical properties, biochemical composition and nutritional qualities of selected eight rice varieties viz., BPT-5204, IR-64, Jyothi, KRH-2, MAS-946, Thanu, Karimundga and KRH-4. Rice cultivars differed significantly in respect of milling characteristics which is reflected by the significant differences of the rice cultivars with respect physical characteristics like length, breadth, test weight, chalkiness etc. Rice varieties Thanu and Jyothi had significantly lesser cooking time (20 minutes) compared to all other varieties/hybrids which took 25 minutes for cooking. The rice cultivars differed significantly with respect to swelling ratio by weight and it ranged from 3.73 to 4.41, hybrids such as KRH-2 and KRH-4 had higher swelling ratio by weight. Physical characteristics of grains, physicochemical and functional properties of flour was estimated. The investigation revealed variations in most of the parameters studied. Variation in size of the grain, weight and density was evident. Oil absorption capacity was highest in KRH-2 (2.1%) and hydration capacity was highest in Sharada (0.9%). The crude fat content varied from 0.27-1.67 per cent. BPT-5204 was found to have high protein about 8.27%. Studies on in vitro protein digestibility revealed highest digestion in BPT-5204 (92.91%) and least digestion in KRH-2 (71.1%). Starch content varied between 42.61 to 55.98% and amylose content varied between 29.23 to 38.1%. Starch digestibility was highest in Karimundga (47.44%) and least in Sharada (31.39%).ThesisItem Open Access UTILIZATION OF BUTTERMILK AND WHEY FOR VALUE ADDITION IN BAKERY PRODUCTS(University of Agricultural Sciences GKVK, Banglore, 2012-11-05) ELNAZ SADEGHIAN, LODERICHEH; Dr. NEENA JOSHIWhey and buttermilk are nutritional by-products of dairy industry. Utilization of buttermilk and whey as a functional ingredients, to add value to selected bakery products (cake, bread and cookie) was explored. Effect of replacement of liquid portion in traditional recipes with whey and buttermilk at different levels (50%, 75% and 100%) on physico-chemical, organoleptic, storage and nutritional property of products were investigated. Substitution of whey and buttermilk brought about an improvement in physical characteristics such as volume, specific volume, spread factor, height in the baked products such as cake, bread and cookie. Organoleptic characteristics, color of crust, moth feel improved with substitution of whey and buttermilk. Cake and bread with substitution of whey and buttermilk retained moisture more effectively during storage compared with control. The stored products prepared with whey and buttermilk were more acceptable than control. Microbial analysis indicated that substitution of whey and buttermilk did not have effect on shelf life of baked products. Utilization of whey and buttermilk in liquid form improved nutritional composition of baked products marginally, specially micronutrients. Best level of substitution was 75% for cake, 50% for bread and 100% for cookie Thus, it may be concluded that based on physical, organoleptic, storage and nutritional characteristics utilization of buttermilk and whey for value addition in bakery products offers advantage over the traditional products.ThesisItem Open Access MYCORRHIZAL DEPENDENCY OF MAIZE AS INFLUENCED BY SOIL NUTRIENT AMENDMENTS IN AN ALFISOL(University of Agricultural Sciences GKVK, Banglore, 2013-05-24) ASHWINI, O.G.; ManjunathNo AbstractThesisItem Open Access CONTENT ANALYSIS OF AGRICULTURAL INFORMATION IN SELECTED MALAYALAM DAILIES, READING BEHAVIOUR OF FARMERS AND THEIR SUGGESTIONS(University of Agricultural Sciences GKVK, Banglore, 2010-08-25) SAMEER, V.M.; D.
