Where does maize grow best?
Maize grows best on deep, well-drained, fertile soils, and where total seasonal rainfall exceeds 500 mm. Maize is reasonably tolerant to soil acidity, but if the soil is very acid, liming will improve the soil and enhance maize yields. Maize is susceptible to both drought and water- logging.
