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.

    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.

    EFFECT OF DYEING ON PHYSICAL PROPERTIES AND COLOUR FASTNESS OF UAS SHEEP BREED WOOL
    (University of Agricultural Science, Dharwad, 1999) Neelima, G Mahale,; Geeta
    "The present investigation was carried out during the period 1998-99. The main objectives of the study were, to determine the effectiveness of acid and reactive dyes on UAS sheep breed wool fibre and yam, to assess the physical parameters of UAS sheep breed wool sample before and after dyeing and to find out the colour fastness properties of the dyed sample for different parameters like sunlight, washing, perspiration, crocking and hot pressing. The triple cross bred UAS sheep breed wool was selected from Poultry, Sheep and Goat Department, Main Research Station, University of Agricultural Sciences, Dharwad. Wool sample collected was of mixed lot from two different shearing seasons namely Spring clip (March) and Autumn clip (September). The wool sample was cleaned, carded and spun into a yam with the help of Medleri charaka. Later it was scoured and dyed with acid and reactive dyes. The effect of scouring and dyeing on wool was found out by assessing the physical parameters of wool fibre and yam before scouring, after scouring and after dyeing. Colour fastness tests to washing, crocking, perspiration, hot pressing and sunlight were carried out ^and was assessed with the help of gray scale. The results obtained were statistically analysed using completely randomized design and correlation test. Results revealed that scouring had more adverse effect on wool than dyemg. Higher absorption was exhibited by acid dyes. Acid dyes were safer on wool than reactive dyes. They had least effect on the physical parameters of UAS sheep breed wool fibre and yam after dyeing. The colour fastness of acid and reactive dyes to washing was very good, to crocking was good, to perspiration was fair, to hot pressing was excellent and colour fastness to sunlight was found to be good."
