Abstract:
A field experiment was conducted at Agronomy Farm, College of Agriculture, Nagpur during rabi season of 2020-21 to evaluate the effect of different combinations of herbicides on weed control yield and economics of wheat (Triticum aestivum L.) on clayey and slightly alkaline soil. The experiment was laid out in randomized block design with ten treatments replicated thrice. Results reveal that among all herbicidal treatments, combinations of post emergence application of clodinafop propargyl + metsulfuron methyl @ 0.06 + 0.004 kg a.i. ha^-1 at 35 DAS was found to be the most effective for higher weed control efficiency (88.67%), number of effective tillers per meter row length (139.40), spike length (7.92 cm), number of grains per spike (38.11), grain (28.90 q ha^-1) and straw yield (33.86 q ha^-1) of wheat which resulted in maximum harvest index (46.04%), net monetory returns (56743 ₹ ha^-1) and B:C ratio (3.05) followed by post emergence application of sulfosulfuron + metsulfuron methyl @ 0.03 +0.002 kg a.i. ha^-1 at 35 DAS with 54631 ₹ ha^-1 net monetory returns and 2.94 B:C ratio.
