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 EFFECT OF FOLIAR APPLICATION OF MICRONUTRIENTS AND MAGNESIUM ON THE GROWTH. YIELD AND QUALITY OF MULRERRY (Morus alba Linn. )(UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 1980) LOKANATHA, R; SHIVASHANKAR, KAbstract not availableThesisItem Open Access ECONOMICS OF SILK COCOON PRODUCTION IN GULBARGA DISTRICT, KARNATAKA(University of Agricultural Science, BANGALORE, 1996) DODMANI, M T; MUNDINAMANI, S MKarnataka is one of the leading states in the country in the production of mulberry silk. An attempt was made in the present study to analyse the economics of mulberry cultivation and silk cocoon production in Jewargi taluk of Gulbarga district. Mainly primary data~ was used for evaluating the objectives of the study. The required primary data was elicited from 97 sericulturists at random, spread over five villages of Jewargi taluk. Tabular analysis was used to compute costs and returns in mulberry cultivation and silk cocoon production. Production function analysis was carried out to assess the resource use efficiency in mulberry cultivation. The per hectare establishment cost of mulberry garden was Rs. 6,534.17. The total maintenance cost of mulberry cultivation per hectare was Rs.l9,766 of which the operational cost accounted for 70 per cent and rest was fixed cost. The gross and net returns from mulberry cultivation were Rs.32,858 and Rs.l3,091 respectively. The returns per rupee of investment was Rs.l.66. The total cost of silk cocoon production was Rs.36,364 • per hectare. The operational cost accounted for over 98 per cent. On an average, 923 kg of silk cocoons was obtained by rearing 2400 laying in one hectare of mulberry crop per annum. The gross and net returns realised from silk cocoon was Rs.87,952 and Rs.51,588 respective l y. The major problems encountered by t h e sericulturists in mulberry cultivation were shortage of irrigation water during summer and attack of pests and diseases for mulberry crop. In silk cocoon production, non-availability of disease free laying, shortage of rearing equipments and attack of uzifly were the major problems. The problems of water shortage could be reduced by intensive use of available water by adopting drip or sprinkler irrigation systems. The pest and disease problem in sericulture enterprise can be controlled by educating the farmers on timely use of appropriate chemicals and disinfectants.ThesisItem Open Access EFFECT OF FOLIAR NUTRITION ON GROWTH, YIELD AND QUALITY OF MULBERRY IN RELATION TO SILK COCOON PRODUCTION(University of Agricultural Science, BANGALORE, 1996) VISWANTH, G K; JAYARAMAIAH, MAbstract not availableThesisItem Open Access EFFECT OF IRRIGATION SCHEDULES, LAND MANAGEMENT PRACTICE AND CALCIUM NUTRITION ON GROWTH AND YIELD OF GROUNDNUT (Arachis hypogaea L.)(UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 1991) RAMACHANDRAPPA, B K; KULKARNI, K RAbstract not availableThesisItem Open Access EPIDEMIOLOGY AND MANAGEMENT OF TURCICUM LEAF BLIGHT OF MAIZE CAUSED BY Exserohilum turcicum (Pass.) Leonard and Suggs(University of Agricultural Sciences GKVK, Banglore, 2007-08-31) SHARANAPPA I. HARLAPUR; M.S. KULKARNITurcicum leaf blight disease of maize caused by Exserohilum turcicum symptoms were recognised by long spindle shaped necrotic lesions with grey colour centre, immature and chaffy ears. The disease appeared in severe form in most of the maize growing areas of Kamataka. Crop loss estimation studies revealed that, avoidable grain and stover yield losses in susceptible genotype were to the extent of 52 and 40 per cent, respectively. Linear regression crop loss models were developed. Arabhavi isolate recorded high virulence. Sixty-five days old plants found vulnerability to infection. An incubation period of 28 hours was found ideal for more than 90 per cent spore germination. Saccharum arundinaceum Retz. was identified as a potential alternative host to E. turcicum and plays an important role in the epidemiology of TLB in Karnataka. Significantly maximum disease severity was noticed in crop sown on 16^ September. Crop sown between Februaiy and April found least affected. The weather factors, viz., minimum temperature (11.3-21.4®C), maximum temperature (26.3-29.4°C), relative humidity (58.7-84.5%) and rainfall (47.104 mm) were highly favourable for disease epidemic. The locations, viz., Arabhavi, Dharwad, Devihosur, Sankeshwar and Nagenahalli were identified as "hot spots' in Kamataka. Significant and positive correlation existed between rainfall and relative humidity with spore load. The genotypes, viz., Allrounder, IB-8501, Cargill 900M, Hi-Shell, NAC-6004, C-111, KH-517, Kaveri 235 and NK-6240 were identified as slow blighters. The disease was responsible for photosynthesis loss to the extent of 89.40 per cent in susceptible genotype. Fourteen inbrei lines were identified as highly resistant sources. The QPM genotypes HQFM-4 and HQPM-5 found highly resistant. Integration of 'olerant hybrid DMH-2 and seed treatment with carboxin power (2 g/kg) or combined seed treatment with Azospirillum sp. (25 g/kg) and T^choderma harzianum (6 g/kg) followed by three sprays with mancoze? (0.25%) was found to be the most effective IDM package for the management of TLB of maize.ThesisItem Open Access "ANALYSIS OF YIELD GAP AND TECHNOLOGICAL GAP IN HIGH YIELDING VARIETIES OF PADDY CULTIVAT.ION IN MANDYA DISTRICT"(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2007-05-04) SUNIL, R; NAGABHUSHANAM, KAbstract not availableThesisItem Open Access A CRITICAL ANALYSIS OF ENTREPRENEURIAL BEHAVIOUR OF RURAL AND URBAN WOMEN ENTREPRENEURS(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2007-09-19) SAVITHA, C.M; SIDDARAMAIAH, B. SWomen as entrepreneur are economically more powerful and contribute to the upliftment of the family. Entrepreneurship is a composite phenomenon which is determined by several factors. The present study was taken up with an objective of measuring the entrepreneurial behaviour of women entrepreneurs in rural and urban areas and to study their characteristics. The investigation also covered the SWOT analysis of EDPs organized by the selected training institutes. The study was carried out utilizing 120 women entrepreneurs from Bangalore (rural) and (urban) districts. A scale was developed to measure the entrepreneurial behaviour of women. Data was analysed with suitable statistical tests The major findings of the study were (i) the entrepreneurial behaviour index of urban women was significantly higher than that of rural women; (ii) the entrepreneurial behaviour of both rural and urban women were positively and significantly related with their education, marital status, birth order, family support, socio-economic status, deffered gratification, socio-political participation, cosmopoliteness, mass-media participation, ownership of enterprise, extent of investment and training received. While it was negatively and significantly related with age and family dependency ratio; (iii) the results of regression indicated that all the 16 variables put together explained 86 percent of the variation in case of rural women entrepreneurs and 98 percent in case of urban women entrepreneurs. Family dependency ratio, mass media participation and financial assistance had made significant contribution to the entrepreneurial behaviour of rural women where in case of urban women family support, cosmopoliteness, institutional support, socio-economic status and financial assistance made significant contributions; (iv) the results of SWOT analysis pointed out that the major strengths of EDP were (a) conducting of need assessment (b) brain storming session (c) developing comprehensive course content; (v) both urban and rural women entrepreneurs experienced several production, financial, marketing and personal constraints while running their enterprise. Department of Agricultural Extension University of Agricultural Sciences, Bangalore-65ThesisItem Open Access STUDIES ON EARLY BLIGHT OF POTATO CAUSED BY Alternaria solani (Ellis and Martin) Jones and Grout(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2016-01-29) RANGANATHA, R. N; Somasekhara, Y. MPotato is one of the most important staple food crops, ranking fifth and fourth place in area and production in the world, respectively. Among various diseases, Alternaria leaf spot is one of the most destructive disease on potato. Cultural studies revealed that, the growth of the pathogen was maximum on solid Potato Dextrose Agar medium (78.11 mm) and maximum fungal dry matter (188 mg) was observed in Potato Dextrose broth medium. The favourable temperature for the growth of the fungus was range between 30 ºC to 35 ºC. The maximum mycelial dry weight obtained at pH 6.0 (157 mg) to 6.5 (152 mg). In vitro evaluation of fungicides revealed that, the fungicide Tebuconazole (100 %), Hexaconazole+Zineb (95.18 %) and Trifloxystrobin+ Tebuconazole (88.15 %) inhibited pathogen growth at 1000 ppm concentrations. T.viride IIHR-21 (69.63 %) and T.viride IIHR-22 (66.30 %) were found effective against A. solani. The crude leaf extracts from nine plants (Calotropis, Lantana, and Lemon grass, Nagadhale, Neem, Pongamia, Simarouba, Subabul and Tulasi) were tested against A. solani and found that Simarouba leaf extract (54.44 % at 1:1 dilution ) showed maximum inhibition of the pathogen. Under glass house condition Tebuconazole (48.33 % at 90 days) reduced disease severity and increased yield in Potato. The field evaluation offungicides, bioagents and sea weed extracts indicated that Mancozeb @ 0.2 % > Hexaconazole+Zineb @ 0.2% > Tebuconazole @ 0.1 % > Metalaxyl+ Mancozeb @ 0.2% > Tebuconazole+ Trifloxystrobin @ 0.1 % > Fenamidone+Mancozeb @ 0.2 % most effective in reducing severity (36.63 % at 90 days) of the early blight disease and increasing tuber yield (61.33 Kg/plot). In untreated check the disease severity was 83.03 per cent with plot yield of 32.66 kg. The foliar spray of fungicide combination is useful in the better management of early blight of potato.ThesisItem Open Access STUDY ON SUPPLY CHAIN MANAGEMENT OF CHEMICAL FERTILIZERS IN HEMAVATHI COMMAND AREA OF KARNATAKA(University of Agricultural Sciences, Bengaluru, 2014-12-21) MANJUNATH, S.; RAME GOWDA, P. V.Supply chain management is concerned with the efficient integration of the entities involved so that merchandise is produced and distributed in the right quantity to the right location and at the right time. The study on Supply Chain Management of chemical fertilizers was undertaken in two taluks of Hemavathi Command Area of Tumkur district. Hundred farmers, ten retailers and four dealers of chemical fertilizers were randomly selected. Tabular analysis and Garret ranking tools were used to analyse the data. The study indicated that three most important marketing channels were present and among them, Manufacturer Wholesaler’s Private Retail dealer’s Farmers was most popular channel in the study area. Seventy per cent of the traders were using company’s vehicle, twenty per cent were using hired vehicles and ten per cent were using own vehicles. Immediate delivery of fertilizers after placing the order was noticed and no need of fertilizer advance booking. Major problems encountered by farmers are found to be lack of scientific knowledge on kind of fertilizer and dosage, long distance to retail outlets, non availability of fertilizer in right time. Problems encountered by fertilizer distributors are found to be timely non-supply of fertilizers, transportation cost, period of credit, inadequacy of retail outlets and higher taxes. The fertilizer companies and KSDA shall conduct training to the farmers on dosage and type of fertilizer application.
