The aim of this study was to evaluate the physiological quality and seed production of Fabaceae and corn in monoculture and intercropping in areas cropped under different management. The following treatments were evaluated: corn + NPK + weed control; corn + weed control; corn + NPK; corn + crotalaria; corn + jack bean. Intercropping raised the average number of corn ears of corn and the seed IVG Weed control positively influenced the final stand and average number of ears. NPK fertilization on corn sowing positively influenced the seed electrical conductivity. The yield of corn plants intercropped with crotalaria and jack bean was statistically similar. However, their absolute values should be considered for economic purposes. Corn seeds derived from intercropping with crotalaria were more effective compared with intercropping with jack bean. Crotalaria and jack bean seeds when intercropped with corn have high production, germination and vigor (IVG and emergence).
