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.

    Variability and Integrated Management of Spot Blotch of Wheat Caused by Bipolaris sorokiniana (Sacc.) Shoem.
    (University of Agricultural Sciences, Dharwad, 2017-07) Ashwini, R.; Patil, P.V.
    Laboratory and field experiment were conducted at Department of Plant Pathology, College of Agriculture and Main Agricultural Research Station, Dharwad to study the variability and integrated management of spot blotch of wheat. Roving survey conducted in Dharwad, Belagavi, Gadag, Bagalkote and Vijayapura districts during rabi, 2017-18 indicated low severity of spot blotch disease. Variability study in 14 isolates of B. sorokiniana through morphological and cultural characters, pathogenic ability and SSR markers had showed high distinction. Colony colour ranged from whitish black to black. On the basis of pathogenicity, 14 isolates were grouped into two different pathotypes (P1 and P2). Similarity coefficients were ranged from 0.53 to 0.98 representing less than 53 per cent genetic variability among isolates. Under in vitro studies, captan at 0.3 % (86.29 %), hexaconazole, propiconazole and tebuconazole at 0.025 %, 0.05 %, 0.1 % (100%), hexaconazole 5 % + captan 70 % WP, carboxin 37.5 % + thiram 37.5 % WP and tebuconazole 50 % + trifloxistrobin 25 % WG at 0.05 %, 0.1 %, 0.2 % (100%), multineemore at 1.0 % (54.81 %) recorded maximum inhibition of mycelial growth. Trichoderma harzianum + Pseudomonas fluorescens + Bacillus subtilis (3.3 g each/l) concentration, panchagavya (20 %) inhibited 80.44 and 30.29 per cent spore germination, respectively. In Integrated disease management, among the eight spray schedules evaluated under field condition, two sprays of hexaconazole 5 % EC (0.1 %) with 15 days interval reduced the spot blotch severity by 13.40 per cent with highe st grain yield (13.33 q/ha), biomass (8.33 t/ha) and BC ratio (1:1.94). Hexaconazole 5 % EC (0.1 %) was most effective in managing spot blotch disease.

    Effect of Nitrogen Levels and Modified Urea on Growth, Yield and Nitrogen use Efficiency in Rainfed Pearl Millet [Pennisetum glaucum (L).]
    (University of Agricultural Sciences, Dharwad, 2017-06) Ganapati
    A field experiment was conducted to study the effect of nitrogen levels and modified urea on growth, yield and nitrogen use efficiency in rainfed pearl millet during kharif 2016 at Regional Agricultural Research Station, College of Agriculture, Vijayapura, UAS, Dharwad. There were 15 treatment combinations involving three nitrogen levels viz., 25, 50 and 75 kg ha-1 and five modified ureas viz., neem coated, tar coated, sulphur coated, vermicompost coated and normal urea. The experiment was laid out in factorial randomised block design with three replications. The results indicated that, application of 75 and 50 kg N ha-1 were at par and recorded significantly higher grain (2,878 and 2,730 kg ha-1, respectively) and stover yields (5.32 and 5.15 t ha-1, respectively) compared to 25 kg N ha-1(2,296 kg ha-1 and 4.00 t ha-1, respectively). Application of neem coated urea recorded significantly higher grain (2,965 kg ha-1) and stover yields (6.13 t ha-1) to normal urea. Net income and benefit cost ratio were higher with application of 75 kg N ha-1 (Rs. 28,815 ha-1 and 2.91, respectively) compared to 25 kg N ha-1 (Rs. 21,366 ha-1 and 2.57, respectively), however it was at par with 50 kg N ha-1 (Rs. 27,517 ha-1 and 2.90, respectively). Among the modified ureas, neem coated urea recorded significantly higher net income (Rs. 32,316 ha-1) and benefit cost ratio (3.32) compared to normal urea (Rs. 23,817 ha-1 and 2.69, respectively) and other modified ureas. Application of 50 kg N ha-1 with neem coated urea was found to be optimum in pearl millet crop to achieve higher grain yield, stover yield and economic returns.
