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.

The in vitro effect of Sanosil and two check chemicals viz. Carbendazim and Mancozeb on spore germination, mycelial weight and hyphal growth of spoilage fungi was studied. Three spoilage fungi namely Pestalotiopsis mangiferae stey. and Aspergillus fumigatus Fresenius, Rhizopus stolonifer Lind. were isolated from spoiled mango and guava respectively. Fruits collected from market had higher microflora than those collected directly from the orchard. The minimum inhibitory concentration of three biocides against spore germination of Pestalotiopsis mangiferae was 1,000 ppm in Carbendazim and 5,000 ppm in Sanosil and Mancozeb, whereas in Aspergillus fumigatus application of Carbendazim. Sanosil and Mancozeb at 1,000 ppm in each case completely inhibited spore germination. However, in Rhizopus stolonifer \he spore germination was completely inhibited in Carbendazim and Mancozeb at 1,000 ppm and in Sanosil at 5,000 ppm. Mycelial weight and hyphal growth were also controlled by all the three biocides at higher concentrations, but the growth was not checked completely. In vivo studies the effect of biocides on shelf life and post harvest qualities of fruits were maintained for longer period and spoilage was reduced significantly. Carbendazim (500 ppm) and Sanosil (10,000 ppm) dipped fruits maintained low TSS, reducing sugar, PME and high ascorbic acid content compared to untreated fruits. In cold storage there was no spoilage upto 10 days in mango and treatment with Carbendazim (500 ppm), Sanosil (10,000 ppm) and Mancozeb (1,000 ppm) could extent shelf life upto 20 days. The TSS, reducing sugar and PME were low In treatment with Carbendazim 500 ppm and Sanosil 10,000 ppm. But ascorbic acid content and titrable acidity were high compared to all other treatments. Hence, Carbendazim (500 ppm) and Sanosil 10,000 ppm treated fruits for five minutes maintained high post harvest quality and low spoilage.ThesisItem Open Access SEED BORNE NATURE OF AZOTOBACTER CHROOCOCCUM IN CHILLI {CAPSICUM ANNUUM L.) AND ITS ROLE IN PLANT GROWTH(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1998-08-19) SHARMA, JAYALAKSHMI S.; ALAGAWADI, A.R.Investigations were carried out on seed borne nature of Azotobacter in chilli and their role in plant growth at the Department of Agril. Microbiology, University of Agricultural Sciences, Dharwad. Azotobacter sp were isolated from both surfacesterilized and unsterilized seeds of 14 varieties of chilli at different stages of fruit maturity. The occurrence of Azotobacter in surface sterilized seeds was lower than that of unsterile seeds. The representative isolates were identified as A. chroococcum. A significant difference in percent seeds yielding Azotobacter was observed between the varieties. Among the varieties, Lathigolar and NP31 harboured highest and lowest population of Azotobacter respectively. The two varieties also had respectively highest and lowest ascorbic acid content. Ascorbic acid was found to stimulate the growth and nitrogen fixation by seed isolates. The competitive survival ability of seed borne Azotobacter in soil was poor as compared to soil isolates. Interaction studies of seed borne Azotobacter isolates with soil bacteria indicated that all the isolates were inhibited by Pseudomonas sp but were stimulated by Bacillus subtilis is. However, Serratia marcescens stimulated nine and inhibited two i solates. The presence of seed borne Azotobacter in different plant parts of aseptically grown chilli seedlings was also detected and their movement from Seed to other plant parts was confirmed by inoculating antibiotic resistant marker strains to surface sterilized seeds and reisolating them from different parts of aseptically grown chilli seedlings on antibiotic containing medium. Pesticides like dimethoate and methyl parathion inhibited the growth of seed isolates at higher concentration but phosphomidon had no inhibitory effect. Seed borne Azotobacter isolates were found to produce lAA, GA and several amino acids, besides fixing atmospheric nitrogen. Inoculation with these strains increased the seed germination, root and shoot length and total dry matter content of chilli plants significantly in both sterilized and unsterile soil .ThesisItem Open Access MINERAL PHOSPHATE SOLUBILIZATION BY BACTERIA AND THE ROLE OF PYRROLO QUINOLINE QUINONE (PQQ)(UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 1998) DINESH KUMAR, T K; SIDDARAME GOWDA, T KAbstract not availableThesisItem Open Access EFFECT OF PAPER MILL EFFLUENT IRRIGATION ON SOME CHEMICAL AND MICROBIOLOGICAL PROPERTIES OF SOIL(UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 1997) VISWANATH, N R; BAGYARAJ, D JAbstract not availableThesisItem Open Access SCREENING AND PERFORMANCE OF EFFICIENT VA MYCORRHIZAL FllNGl FOR TREE SPECIES SUITABLE FOR AGROFORESTRY(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1998-08-19) GURUMURTHY, S.B.; SREENIVASA, M.N.A survey work was conducted to isolate the predominant spore types from the rhizosphere soil of five major tropical tree species viz., teak,. silveroak, casuarina, shisham and tamarind. After isolation of predominant local isolates or VAM fungi from each tree species, they were mass multiplied in rhodes grass using sterilized sand, soil (1-1) mix. Two predominant local isolates and four standard VAM -ungi were-used for screening and selection of- efficient VAM fungi for. all the. .five tree species. The results of this trial clearly ^ brought out that the efficient VAM fungus for inoculating at nursery level is SclQracystis dussii for teak, Gigaspora margarita for silveroak and tamarind, and Glomu's f3.sciculatuin.tox casuarina and shishai. After selection of efficient VAM fungi for each tree species the second experiment was carried out to determine the optimum P-dose using differMt levels of phosphorus (0,50, 75 and 100 kg P2O5 psr hectare as single superphosphate). The results clearly indicated that the optimum level of phosphorus was 75 kg P7O5 per hectare for teak and silveroak, 50 kg P2O5 per hectare for casuarina, shisham and tamarind which can be used to harness maximum benefits rrom inoculations with respective efficient VAM fungi. After knowing efficient VAM fungi and optimum level of^ P-dose. for each tree species in the previous trails, the third set of experiment was carried out to study the effect of dual inoculation of efficient VAM fungi and P-solubilizer Pseudomonas striata using two forms of phosphorus [Rock phosphate (RP) and single superphosphate (SSP)]. The results of this study clearly brought that dual inoculation of efficient VAM fungi and P-solubilizer to be superior in improving growth, nutrition and dry matter production of all the five tree species. Among two forms of P, rock phosphate was found to be superior in improving growth, nutrition and dry matter production of all the five tree species.ThesisItem Open Access PERFORMANCE OE ARBUSCULAR MYCORRHIZAL FUNGI IN CHILLI (Capsicum annuum L.)
