Abstract:
The experiment aimed to study the effects of different weed control treatments on wheat yield attributes during Rabi 2020-21. Three different treatments of weed control were used in the experiment. They were Weedy Check (treatment involved leaving the crop without any weed control measures allowing the weeds to grow naturally); second treatment involved the application of a weedicide mixture containing Clodinofop and Metsulfuron) at 35 days after sowing.; and third treatment involved the application of a mixture of weedicides, namely Isoproturon and 2, 4-D at 35 days after sowing. The results of the experiment indicated that the application of the weedicide mixtures Clodinofop + Metsulfuron and Isoproturon + 2, 4-D resulted in higher yield attributes and grain yield when compared to the weedy check. (Without weed control). The highest recorded grain yield was 5038 kg ha^-1 in the Clodinofop + Metsulfuron (RM) treatment. Additionally, the straw yield was recorded as 7563 kg ha^-1, and the biological yield was 12602 kg ha^-1 in the same treatment. These results suggest that the use of Clodinofop + Metsulfuron weedicide mixture was effective in controlling weeds and significantly improved crop productivity compared to the untreated weedy.
