A field experiment was conducted during the Rabi (winter) season of 2014-15 and 2015-16 at Agricultural Research Station, Dharwad, Karnataka, India to evaluate the efficacy of tank mix herbicides and premix herbicides on weed control and its influence on productivity and profitability in irrigated wheat. Tank mix application of sulfosulfuron + metsulfuron 25 + 4 g/ha recorded significantly higher grain yield (4.31 t/ha) followed by clodinafop + metsulfuron 60 + 4 g/ha (4.15 t/ha) over weedy check. Biological yield was recorded significantly higher with clodinafop + metsulfuron 60 + 4 g/ha (12.21 t/ha) followed by sulfosulfuron + metsulfuron 25 + 4 g/ha (12.18 t/ha) over 2,4-D 2.5 kg/ha (10.68 t/ha) alone. The lower weed density, weed biomass and higher weed control efficiency was recorded with sulfosulfuron + metsulfuron 25 + 4 g/ha followed by clodinafop + metsulfuron 60 + 4 g/ha compared to weedy check. The more gross returns, net returns and benefit : cost ratio was obtained with sulfosulfuron + metsulfuron 25 + 4 g/ha over other weed management practices.

The bread wheat variety UAS 375 was released by Central Subcommittee on Crop Standards, Notification and Release of variety, Ministry of Agriculture, Govt. of India vide. S.O. 1379(E) dated: 27.03.2018 for cultivation in the Peninsular Zone of the country comprising states of Maharashtra and Karnataka. UAS 375 has recorded average yield of 21.4q/ha with potential yield of 29.1q/ha. It has shown yield superiority of 14.4% over the best check variety NI 5439 (18.7q/ha) during three years of testing under timely sown, rainfed conditions. The variety UAS 375 has shown resistance to prevalent pathotypes of stem and leaf rusts in the target environments and has combination of Lr13+1+ and Sr7b+2+ genes for diversified gene deployment against these rusts. It has better grain, product as well as nutritional quality parameters which makes it preferable variety for product developments. High yield potential of the variety UAS 375 under rainfed conditions coupled with disease resistance and quality traits makes it a suitable choice for the wheat growing farmers of the Peninsular India.
