Abstract: A field experiment was conducted during rabi 2017-18 at Rajasthan College of Agriculture, MPUAT, Udaipur (Rajasthan) to study the response of barley (Hordeum vulgare L.)to different herbicidal treatments. The experimental results revealed that application of pre-mix herbicide halauxifen + florasulam + polyglycol at 32 days after sowing recorded the maximum degree of reduction in the density as well as dry matter of broad-leaved weeds at 30 days after spray compared to the remaining treatments. Ready mix herbicide, halauxifen + florasulam + polyglycolalso recorded the maximum plant height, dry matter accumulation and maximum values of yield attributes viz. effective tillers 0.5 metre-1 row length (39.33), grains ear-1 (28.33), grain weight ear- 1 (1.26 g), ear length (7.77 cm) and test weight (44.52 g) which ultimately reflected into more economic yield (3846 kg ha-1). As a consequence, statistically superior net return (Rs. 40,930 ha-1) and B-C ratio (2.35) were recorded under this treatment as compared to weedy check.
