Resumo
Green fertilizers can promote a significant weeds control, due to their fast growth rate, increasing the interspecific competition, mainly for space. This study aimed to evaluate the intercropping Crotalaria juncea L. sowing methods on weeds suppression and seeds yield. The experimental design was randomized blocks, with four treatments (sowing at 0.50 m and 0.75 m between rows, haul, and control) and three replications. At 50 days after sowing (DAS), the weeds density and specific composition were determined. For determining dry mass, weeds and Crotalaria juncea were collected at 100 DAS, while, at 200 DAS, only weeds were collected. Then, the data were submitted to variance analysis and means compared by using the Tukey test, at 5%. It was possible to conclude that the presence of Crotalaria juncea inhibited the development of the weeds community, with no differences among treatments. The same occurred for seeds yield.
