ABSTRACT: 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).
