Abstract:
Results of field experiment carried out during rabi 2017-18 and 2018-19 at Instructional Farm, Rajasthan College of Agriculture, Udaipur, indicated that various weed-control treatments significantly influenced weed control efficiency, yield and yield attributes of barley (Hordeum vulgare L.) and thereby significantly enhanced economic returns. Maximum weed control efficiency of total weeds at harvest was recorded with tank mixture of pinoxaden 40.0 g ha^-1 and carfentrazone ethyl 20.0 g ha^-1 35 DAS(W5) (88.65%) after weed free treatment. This treatment gave 25.65% and 26.16% more grain and straw yield, respectively on pooled basis compared to weedy check. Maximum yeild attributing characters viz. effective tillers per meter row length( 80.69), grains per ear (47.23), ear length (6.19 cm), grain weight (1.97 g ear-1) and 1000 grain weight (41.59 g) were observed under tank mixture of pinoxaden 40.0 g ha^-1 and carfentrazone ethyl 20.0 g ha^-1 35 DAS (W5) after weed free treatment. Maximum net returns (71863 Rs/ha) and BC ratio (2.38) were also observed under this treatment. The net returns and yield as well as yeild attributing characters of the crop were maximum under90 kg N ha-1, however these were found at par with 75 kg N ha-1. Maximum B C ratio (2.23) was recorded under 90 kg N ha-1which was statistically at par with 75 kg N ha^-1 (2.19).
