Maize should be harvested as soon as the grain is dry and grain moisture is at or below 15%. Delayed harvesting leads to lodging and damage by birds, storage pests and diseases. In dry savannah areas, the grains could be allowed to dry on the field before harvesting. If left on the field to dry, the crop is ready for harvesting when cobs start dropping. In the Forest and Forest-Savannah transition zones, usually it may be raining at the time when maize reaches maturity. Under such condition, maize should be harvested from the field early (preferably after two to three days without rain) and dried in the sun or in special drying cribs. The grains should be raked across drying surface regularly to ensure even drying.
