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.

    EFFECT OF EXTRAFOLIATION OF BOTANICALS ON QUALITY CHARACTERISTICS OF MULBERRY SILK
    (University of Agricultural Sciences, Dharwad, 1999) ANGADI, ARCHANA P; MAHALE, GEETA
    The present investigation was conducted in the year 1998-99 in the department of Textiles & Clothing in collaboration with the department of sericulture at the University of Agricultural Sciences Dharwad. The research was done to exploit different weeds, to know the effect of these weeds on the quality parameters of the cocoon as well as raw silk yarn and also to know if there is any allergic effect of the raw silk produced out of extrapolation of Parthenium. The botanicals used for the experiment were Parthenium hysterophorus, Tridax procumbens & Lantana Camara. Due to the abundant availability of these weeds and also based on the earlier studies on these weeds it was decided to use these botanicals for the present investigation. The salient results of the research are: Among the cocoon parameters Parthenium showed better results for cocoon weight and shell weight whereas it was Tridax as far as shell ratio was considered. Among the silk filament parameters it was Tridax which gave better results for denier and average filament length but it was Parthenium for average nonbreakable filament length. For the silk yarn parameters Tridax gave best results for winding breaks, average size, size deviation, evenness and average neatness. Parthenium gave better results for average cleanness, tenacity and cohesion. Lantana gave good result for elongation. In all the parameters it was the treated group which gave best results than the control. As far as allergy test was considered, though all the thirty subjects irrespective of sex had sensitive skin, none of them showed any dermatologic hazards like rashes, redness, itching or burning. The raw silk produced out of extrapolation of Parthenium proved to be safe to manufacture the fabric.
