How can I grow sweet corn in Barbados.? - little corn island

I began a harvest of maize in April, living in Barbados is an island and we know not trropoical corn grow here, and at first everything was fine, the stems of corn has risen four feet, ears EARS OFF then began to seem dry "corn" were about three inches long. Things dried up wet every day becuse it was very hot and the soil drains quickly here. How do I get this corn big enough to collect and maintain health.
