The versatility of intercropping grain crops and leguminous species can benefit the different characteristicsof the farmers. However, the choice of the appropriate species and planting season, is important to reduce competitionbetween species. Thus, in order to increase the production of straw for no-tillage system without interference in cornyields, a randomized block design experiment was proposed, with four replications and 11 treatments composed bysingle crops of maize (Zea mays L.), Crotalaria juncea L. e C. spectabilis Roth, and,sowing dates of corn and crotalariasimultaneously, and in the stages V4, V7 and R4. The results indicated that the intercropping with C. juncea inter-rowsaffected maize productivity; C. juncea single crop produced 8.05 t ha-1 more dry matter compared to C. spectabilis; theuse of C. spectabilis inter-rows in simultaneous planting with corn as well as V4 and V7 stage of maize increased thetotal dry matter production and did not interfere with the harvesting and productivity of maize.
