A study was conducted at the Teaching and Research Farm of the University of Calabar, Nigeria to evaluate the effect of three hedgerow species(Enterolobium cyclocarpum, Dialium guianense and Sesbania macrantha)on the growth and yield of plantain (Musa spp.), cowpea(Vigna unguiculata)and maize(Zea mays)in an alley-cropping system. The growth rate and biomass yields of the hedgerow species as well as the growth and yield of the associated food crops were determined. The highly branched, bushy

Compared with the other hedgerow species, alley-cropping with E. cyclocarpum generally enhanced the growth and bunch yield of plantain, while alley-cropping with S. macrantha decreased the bunch yield of plantain by 9%. The grain yield of cowpea was higher under alley-cropping with the hedgerow species, whereas that of maize was depressed. The overall results indicated the beneficial effect of alley-cropping on plantain and cowpea with the hedgerow species at the early stages of establishment.
