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 Foliar Application of Growth Substances on Seed Yield, Quality and Storability of Soybean (Glycine max L. Merill)
    (University of Agricultural Science, Dharwad, 2017-07) Keerthana C.G.; Vyakaranahal, B.S.
    A field experiment was conducted at the Main Agricultural Research Station, Dharwad, during kharif 2016 with factorial RCBD design, first factor consisted of two varieties namely, JS 335 and DSb 21 and second factor consisted of foliar application of growth substances consisted of six treatments viz., T1: Salicylic acid @ 50 ppm at seedling stage and at pod initiation stage, T2: GA3 @ 50 ppm at seedling stage, T3:Acetyl salicylic acid @ 20 ppm at seedling and pod filling stage, T4: KH2PO4 @ 2 % flowering and pod filling stage, T5: α- tocopherol @ 100 ppm at seedling, flowering and pod filling stage and T6: Control. The vegetative growth characters, seed yield (2,59583 kg / ha) was found superior in the treatment T5 and it was on par with T1 compared to T6. The laboratory experiment was conducted in the Department of Seed Science and Technology, University of Agricultural Sciences, Dharwad for a period of nine months during 2016 - 2017 with factorial CRD design, first factor consisted of two packaging materials viz., cloth bag and HDPE bag and second factor consisted of eight seed treatments. The results revealed that, the higher germination (95.33%), vigour index, low electrical conductivity of seed leachate and low insect infestation was observed in T7: Polymer seed coating @ 5 ml per kg of seeds + vitavax @ 2 g per kg of seeds + deltametrin @ 0.3 ml per kg of seeds compared to control. The foliar spray of α- tocopherol @ 100 ppm at seedling, flowering and pod filling stage (T5) gives higher yield. The seed treatment with Polymer seed coating @ 5 ml per kg of seeds + vitavax @ 2 g per kg of seeds + deltametrin @ 0.3 ml per kg of seeds (T7) maintains better quality.
