Three rotation sequences: continuous wheat, alternating maize-wheat and alternating bean-wheat were studied under conventional and minimum tillage with and without phosphate fertilizer. Results from the trial showed that in 1992 and 1994, bean yields from conventionally tilled plots were significantly greater than yields from minimum till plots. In two seasons (1992 & 1993) wheat yields under minimum and conventional tillage were statistically similar but in subsequent seasons minimum tilled plots yielded significantly less. Significantly higher maize grain yields were obtained under conventional tillage in the first season but no differences in yield were observed in 1994. The effect of rotation on wheat yields were evaluated in the second and fourth seasons. It was observed that wheat yields were similar when wheat was grown either after wheat or beans. However, wheat grown after maize yielded significantly more in the fourth season than wheat grown after wheat or beans. Application of phosphorus at the rate of 80kg P2O5 /ha did not significantly increase the yield of the crops in the study.Collection: CIMMYT Publications Collection
