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.

    DEVELOPMENT OF HERBAL JAGGERY FOR ENHANCED QUALITY AND SHELF LIFE
    (University of Agricultural Sciences GKVK, Bangalore, 2022-03-26) POOJA, KOLAR; JAMUNA, K. V
    Jaggery is the natural sweetener available in solid, liquid and powder form. Jaggery contain micronutrients which has many nutritional and medicinal properties. Medicinal herbs or plants have been known to be an important potential source of therapeutic or curative aids. The present study was undertaken to develop herbal jaggery for enhanced quality and shelf life. In the current study, ugarcane variety VCF0517 was selected for jaggery preparation. Jaggery was enriched with tulsi, mint and ginger in powder form and aqueous extract at the concentration 1.0, 1.5 and 2.0 per cent and enveloped herbal jaggery subjected for physical and sensory parameter. Powder, liquid and cube form of jaggery were developed. Flavored chikki, jaggery chocolates and in tea preparation herbal ggery was used and products were subjected to sensory evaluation. Results showed that on initial day the physical characteristics including pH, moisture, hardness and insoluble solids were found unchanged in both forms of jaggery. Sensory evaluation of developed herbal jaggery record good at 2 per cent concentration. Storage study showed that, as the storage period increased the pH of verbal jaggery decreased from 6.13 to 5.20. Compared to control and aqueous extract the dried herb powder jaggery had less content of total sugar (81.23 to 82.30), reducing sugar (6.42 to 6.59) and sucrose (72.62 to 74.10). Whereas herb powder based jaggery had higher mineral composition, polyphenol, flavonoid and also exhibited more antioxidant activity at 300 μg/ml (76.37 to 88.18) compared aqueous extract. Different forms of jaggery can be used in traditional recipes in the preparation of sweets. Herbal jaggery was also found to be highly suitable for tea preparation as it had very good mouthfeel. Herbal jaggery enriched with Tulsa, mint and ginger enhanced the overall quality of jaggery with respect to nutrition content and bioactive properties.

    AWARENESS, ATTITUDE AND ADOPTION TOWARDS CARBON SEQUESTRATION TECHNOLOGIES IN RICE AND SUGARCANE BASED FARMING SYSTEM
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-10-27) SURESH, D. K.; Shivamurthy, M.
    The present investigation was carried out to assess Awareness, Attitude and Adoption of carbon sequestration technologies in Rice and Sugarcane based farming system. One hundred eighty farmers practicing rice and sugarcane based farming system were randomly selected from Maddur, Mandya, Nanjanagoodu, T. Narasipura, Kollegala and Yelandur taluks of Mandya, Mysore and Chamarajanagar districts. Results revealed that, 37.78 per cent of the farmers were having favorable attitude towards carbon sequestration technologies and 40.00 per cent of them were moderately aware about the carbon sequestration technologies in rice and sugarcane based farming system, where as with respect to adoption only 42.22 per cent of the farmers have moderately adopted carbon sequestration technologies. Correlation analysis indicated the profile characters viz., education, occupation, land holdings, annual income, mass media exposure, scientific orientation, Risk orientation, Farming experience and innovative proneness had a positive and significant relationship at one per cent level; Similarly, age, Extension contact, Management orientation and Cosmopoliteness had positive and significant relationship with attitude towards carbon sequestration technologies at five per cent level. The R2 value indicated that all the 19 independent variables had contributed to the tune of 69.00 per cent of variation in attitude of farmers towards carbon sequestration technologies. While adoption of carbon sequestration technologies, low price for the produce and nonavailability of labors were the top most constraints expressed by the farmers and they also suggested that, RSK’s should ensure supplying of critical inputs at appropriate time in the villages and increasing subsidies on micro irrigation structures beside giving support price based on cost of cultivation were the major suggestions expressed by farmers.

    SURVEY, BIOLOGICAL & MOLECULAR CHARACTERIZATION AND MANAGEMENT OF CUCUMBER MOSAIC VIRUS IN GHERKIN (Cucumis anguria L.)
    (University of Agricultural Sciences GKVK, Bangalore, 41834) Kavyashri, V V; NAGARAJU, N
    Cucumber mosaic virus (CMV) is most destructive disease on gherkin. Survey during 2013-14 revealed that, disease incidence ranging from 16.00 to 59.65 per cent with the highest incidence recorded in Kolar (51.27%) and least in Bangalore rural (17.15%). The virus was readily transmitted by sap and aphids on gherkin cv. green long and showed systemic mosaic with dark and light green or with yellow patches with slight puckering. A single vector, Aphis gossypii per plant was sufficient to transmit disease upto 20 per cent, whereas, 100 per cent transmission was obtained in A. gossypii and 90 per cent in Myzus persicae when 5 and 10 aphids per plant were used with 10 min. acquisition and inoculation access period. Ash gourd, Bottle gourd, Bush squash, Cucumber, Muskmelon, Pumpkin, Ridge gourd, Round melon and Chilli showed mosaic symptoms, Tomato showed shoestring symptom, Chenopodium and Cowpea showed necrotic local lesions upon inoculation with CMV. Virus reacted strongly to cucumovirus specific antisera through DAS-ELISA. PCR product of CMV infected sample with CPprimers indicated ~700bp-DNA and showed high nucleotide homology with the strains of CMV subgroup-IB (95-99%) and sequence conservation of nucleotide (99%) with ANstrain (subgroup-IB). CMV in gherkin was effectively managed by border crop African tall maize + reflective mulch + spraying Lastraw (0.5%) + Neemark (0.5%) + Groundnut oil (1%) at 15 days intervals which recorded the lowest mean per cent incidence (8.05) compare to control (36.00). Out of 43 genotypes screened, Hyb.11 genotype showed immune reaction to CMV.
