Crotalaria produced 3600 - 5900 kg ha-1, and Tephrosia 1500 - 4700 kg ha-1. These values are higher than Zimbabwe, indicating a higher level of soil fertility even on relatively exhausted sites in Malawi. In the 1997/98 season maize will be planted on all plots to examine the residual fertility benefits of the green manure rotation.Collection: CIMMYT Publications Collection
