An experiment was conducted in 2016 cropping season to evaluate residual effect of legumes experimental treatments on maize crop yield at the fields that were used for soybean the previous year at the two agroecological zones (Sudan savanna and Guinea savanna). After clearing and land preparations, experimental plots were demarcated. Plots size was 4 by 4.5m. There were seven treatments replicated four times, each for soybean and groundnut. Maize grain yield showed no significant difference between treatments in terms of maize yield). Result from Sudan savanna soybean field revealed no significant difference between treatments in terms of maize yield (P = 0.123). As for harvest index, there is significant difference (P =0.023) between treatments. On contrast result obtained from Guinea savanna soybean field showed that significant difference exists between treatments. nitrogen treatment recorded highest yield (2175 kg ha-1). Result for major nutrients uptake in maize shoot showed no any significant difference between all the treatments observed in soybean fields at both Sudan savanna and Guinea savanna. From the finding of this study it can be concluded that. Result indicated that residual effect of leguminous crop treatments influenced yield performance of maize in Guinea savanna but no significant difference was observed in Sudan savanna.
