ABSTRACT:
One of the biggest problems found in cowpea production is weeds, due to competition and interference caused by these plants. The study aims to determine the periods of weed interference with the cowpea crop. The study was carried out in a randomized block design, with ten treatments and four replications. Productivity evaluation was performed 80 days after emergence. The PAI found was 8 DAE, PTPI 53 DAE and PCPI 45 DAE. The maximum yield in the control was 3,500 kg ha¹ and the interaction was 2,294 kg ha¹. The crop yield was reduced by 73.5%, which allows us to state that the crop should not coexist with weeds during the critical period of competition.
