University of Agricultural Sciences, Dharwad

The University of Agricultural Sciences, Dharwad was established on October 1, 1986. The University has 5 Colleges, 27 Research Stations, 6 Agriculture Extension Education Centers, 6 Krishi Vigyan Kendras and ATIC. The University has its jurisdiction over 7 districts namely Bagalkot, Belgaum, Bijapur, Dharwad, Gadag, Haveri, and Uttar Kannada in northern Karnataka. Greater diversity exists in soil types, climate, topography cropping and farming situations. The jurisdiction includes dry-farming to heavy rainfall and irrigated area. Important crops of the region include sorghum, cotton, rice, pulses, chilli, sugarcane, groundnut, sunflower, wheat, safflower etc. The region is also known for many horticultural crops. Considerable progress has been registered in the field of education, research and extension from this University.

    PROCESSING OF TOMATO
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, DHARWAD, 2003) Benal, Basapp P; Madalageri, M B
    "An investigation was undertaken on processing of tomato fruits with seven treatments (popular tomato varieties / hybrids) by adapting completely randomised design in the Department of Post-harvest Technology of Kittur Rani Channamma College of Horticulture, Arabhavi during the year 2001-2002. Tomato juice yield was maximum in tomato genotype Asha (71.07%) followed by Avinash-2 (69.43%) and Indam-9714 (67.63%). The TSS content of the fruits ranged between 4.93 per cent in Asha and 4.46 per cent in Utsav. Reducing sugars, nonreducing sugars and total sugars were also significantly high in Asha (1.81, 1.05 and 2.91 per cent, respectively). The pH of fruit juice was least (4.03) in Utsav followed by Avinash-2 (4.36) and Indam-9714 (4.44). Nutritionally important lycopene and ascorbic acid content were in the acceptable range (i.e. more than 5 mg / 100 g) in the fruits of Asha, Avinash-2 and Indam-9714. Significantly highest puree yield was recorded from the fruits of Asha (36.0%) followed by Avinash-2 (33.0%) and Indam-9714 (31.5%). The storage of puree prepared from the tomato genotypes for six months did not undergo much changes in pH and titrable acidity. At the end of six months storage, the puree lycopene retention was highest (17.53 mg/100 g) in Asha followed by Indam-9714 (15.60 mg / 100 g). Reducing sugar was also significantly highest in the puree of Asha (11.16%) followed by Avinash-2 (11.08%) and Indam-9714 (10.87%). Total sugars were higher in Asha (12.84%) followed by Indam-9714 (12.78%) and Avinash-2 (12.64%). At the end of six months storage, the puree from most of the tomato genotypes had negligible non-enzymatic browTiing a s reflected in the little variation in the values (0.26 to 0.39) of optical density (OD). Among the seven popular cultivated tomato genotypes studied, the fruits of Asha, Avinash-2 and Indam-9714 were found to be possessing the qualities suited for processing into puree. Tlie fruits of these genotypes could be processed into puree during market glut period."
