The present investigation was carried out with the objective of evaluating the use of summer green manure coverage as a weed suppressant in a crop rotation system. The experimental design used was randomized complete blocks (DBCA), consisting of five treatments and four replications. The treatments consisted of green manure covers: Canavalia ensiformis (T1), Mucuna pruriens (T2), Cajanus cajan (T3), Crotalaria juncea (T4), Phaseolus vulgaris (T5), a control, conventional system (T6) was also used, mainly the control was used for the determinations of green mass of weeds, height of the pearl millet and green mass of the pearl millet. The determinations evaluated were; coverage persistence (Mg Ha–1) at 0, 15, 30, 45 and 60 days, weed suppression (Mg Ha–1) at 30, 60 and 90 days, green mass of weeds (Mg Ha–1) at 30, 60 and 90 days, height of the Pennisetum glaucum (cm) at 60 and 90 days, green mass of the pearl millet (Mg Ha–1) at 60 and 90 days. The data obtained were subjected to analysis of variance (Test F 5%) and the means of the treatments with significance were compared by Tukey’s test at 5% probability of error. In the determination of the green mass of weeds, significance was obtained between the conventional system (Control) and the green manure covers, so it can be affirmed that the use of vegetable covers reduces the incidence of weeds, greatly benefiting the reduction of competition between the crop. of economic importance in question and weeds.
