Abstract In the 2005/2006 season, the Model Validation Through Long-Term Promising Sustainable Maize/Pigeon Pea Residue Management experiment was in the 11th year at Chitedze and Chitala, and in the 8th year at Makoka and Zombwe. The experiment was a split-plot design with cropping system as the main plot and residue management as the subplot. All treatments were subjected to two fertilizer regimes. In the first regime, there was no addition of inorganic fertilizer and in the second, there was addition of inorganic fertilizer at area-specific fertilizer recommendation rate. The evaluation was done at Chitala, Chitedze, Makoka and Zombwe. Significant differences (P = 0.05) were observed in maize grain yield among sites and cropping systems. Highest grain yields were recorded at Chitedze (5,342 kg/ha). However, the response trend in grain yield to different cropping systems remained the same in all sites. Best yields were recorded in maize grown following pigeon pea in rotation system followed by maize intercropped with pigeon pea. The addition of inorganic fertilizer increased maize yield significantly. Removal or retention of crop residue in the field did not contribute any significant yield increase of maize across sites. For resource-poor smallholder farmers, growing maize/pigeon pea in rotation and maize intercropped with pigeon pea seems to be more profitable in terms of resource utilization and soil fertility improvements
