Means followed by the same letter(s) within the same treatment group are statistically the same and showed no significant difference by DMRT (). , , and mean significant differences at 0.05, 0.01, and 0.001 probability levels, respectively, and NS means nonsignificant differences. mmm, mwm, mww, mwp, mpp, mwfb, and mfbp refer to continuous maize-maize-wheat-maize, maize-wheat-wheat, maize-wheat-pepper, maize-pepper-pepper, maize-wheat-faba bean, and maize-faba bean-pepper, respectively.
