Abstract
Low soil fertility, erratic rainfall, high yield risk, maize streak disease and insect pests and the absence of a protein crop are major technical constraints in Nigeria which could be addressed by IITA technologies. Trials of streak resistant maize intercropped with cassava, as well as cowpea and soybean and alley farming, were selected to initiate the development of new technologies. First results of these trials suggest that short season maize harvested green, full season open pollinated improved maize for grain, and soybean in the second season are promising technologies.
