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.

    ECONOMICS OF SILK COCOON PRODUCTION IN GULBARGA DISTRICT, KARNATAKA
    (University of Agricultural Science, BANGALORE, 1996) DODMANI, M T; MUNDINAMANI, S M
    Karnataka 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.

    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. M
    Potato 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.

    ECOLOGICAL NICHE MODELING FOR CHEMICAL PROSPECTING OF FOREST SPECIES: A CASE STUDY IN Nothapodytes nimmoniana (Graham) Mabb.
    (University of Agricultural Sciences, Bangalore, 2010-01-12) RAGHAVENDRA., H. P.; Ganeshaiah, K. N.
    Ecological Niche Modeling (ENM) has become powerful tool in predicting the geographic distribution of a given species. Being modelling process, it maps the similar habitat conditions corresponding to the habitat type of the places of known occurrence of the species and stratifies the area from most suitable to least suitable habitat for the species occurrences. However, in this study an attempt has been made to test the potentiality of ENM in prospecting for the populations that yield high level of seconday metabolites in particular, CPT. The underlying assumption of ENM here is, the plants in most suitable area are expected to show higher fitness , higher regeneration status, and hence the traits that confirms the fitness would be expected to be high in most suitable area compared to least suitable area. There are hardly any attempts made to this important assumption, however, in this study we provide evidence towards this assumption in specific metabolite, CPT. Therefore we proposed to use ENM to predict the habitat suitability for Nothapodytes nimmoniana (Graham), which produce an anticancer drug, Comptothecin (CPT). Firstly we developed niche map for N. nimmoniana using DIVA- GIS and Maxent. However in this study to validate the ENM assumption, density, regeneration, girth of trees, fluctuating leaf asymmetry, and specific leaf weight were considered as fitness measures. Result indicated that, mean % CPT content is significantly higher in predicted most suitable habitat compared to least suitable habitat wherein population showed higher regeneration status and higher fitness. Therefore, we concluding that, production of CPT in N. nimmoniana could be purely a spin-off of growth and reproduction. Thus, results from this study validated the assumption of ENM accordingly suggested that, ENM could be potentially used to predict the niches of high fitness and area with high level of secondary metabolites.

    At the time o f our Independence, Jawaharlal Nehru said, "Everything else can wait, hut not agriculture”. Unfortunately this profound truth is yet to be converted into concrete policies and action on an adequate scale. The geographical area o f India is 328.7 m illion hectares, net sown area is 142 million hectares and gross cropped area is 190 million hectares. According to 2001 census, the population of India is 1027 millions, of which 742 million constitutes rural population and 285 million constitutes urban population. Our country’s population is increasing at a rate o f 1.90 per cent. In our total population, 128 million constitutes cultivators, 107 million constitutes agricultural labourers and other workers constitute 167 million. Of the world’s six billion people, 2.8 billion live on less than two dollars a day, of whom 1.2 billion live on less than one dollar a day. Unemployment and underemployment are endem ic in the econom ies of the developing world and up to 815 million people are unable to obtain the food they need for an active and healthy life (FAO, 2001). Progress over the last ten years in reducing the number of people living in absolute poverty has been mixed. In East Asia and the Pacific, the number of people in absolute poverty has been reduced by 192 million, but the gains have not been evenly spread between countries. In Africa during the same period, the num ber actually rose by 58 million (Anonymous, 2002). Put crudely, almost half o f the world’s population does not have the socio-economic and political means to realize their economic and social rights. One of the m ajor causes o f poverty is the lack of viable livelihoods in the developing world.

    STANDARDIZATION OF PROCEDURE FOR LIQUID JAGGERY MAKING AND UTILIZATION FOR VALUE ADDITION
    (University of Agricultural Sciences, Bangalore, 2009-11-10) MOHANA KUMARA NAYAKA, N.; USHA, RAVINDRA.
    Production of jaggery is seasonal, therefore preservation and storage of solid jaggery become essential. Large scale storage during monsoon possess serious problem. Hence there is need for alternative procedure for production of good quality jaggery with reduced application of chemical additives. “Standardization of procedure for liquid jaggery making and utilization for value addition” was studied to increase the shelf life of jaggery as well as consumption. Five additives and two preservatives were used in different combinations to obtain good quality liquid jaggery. Assessment of physicochemical, nutritional, storage and microbial quality analysis using AOAC and other procedures. Two value added products such as Ice cream and Milk shake were developed. Liquid jaggery and value added products were evaluated for acceptability. Brix of sugar cane juice ranged from 20.70 to 22.00, pH 5.5 to 6.5 and reducing sugar 4.34 to 6.25 percent. T3 (all additives) was better clarificant followed by T4 (chakke) and T5 (Hydrose). Moisture ranged from 17.80 to 35.93, brix 14.20 to 17.43, sucrose 42.01 to 56.56, purity 73.35 to 85.87, average ash content was 3.42 percent respectively. Protein ranged from 0.36 to 0.95, CHO from 57.35 to 70.64, Energy from 241.43 to 286.24 Kcal, Calcium 72.26 to 78.00, Phosphorus 32.00 to 38.00 mg, Iron from 2.71 to 2.82mg per lOOg respectively. Overall acceptability ranged from 3.65 to 4.20, 3.75 to 4.00 and 3.55 to 3.85 in glass container at zero, 45 and 90 days of storage. Cost benefit ratio of liquid jaggery was 28.60. It could be concluded that procedure for liquid jaggery making requires least amount of chemicals. Nutritional and microbial quality showed positive trend towards extended shelf life. Therefore with little modification in processing by adopting scientific techniques, good quality liquid jaggery can be produced as a small scale enterprise as an income generating activity.
