Extension service, video movies, leaflets, and mass communication media have been Widely used to instruct and encourage farmers to grow maize and to apply new technologies. Major areas identified to conduct future research on maize are: a. Develop high yielding OPV's and hybrids. b. Breeding for short plant height, early maturing varieties (75-80 days). c. Select varieties for adverse environmental conditions. d. Studies on postharvest technologies. Table 4. Crop Per hectare costs and returns of selected subsidiary food crops.
