Abstract

Four field trials were conducted to examine the effect of various management practices on sweet potato yield in the sweet potato x corn mixture. The results showed that sweet potato marketable yields were significantly lowered when intercropped with simultaneously planted corn. Sweet potato planted before corn, however, was able to attain yields similar to those of the pure stand. Significant cultivar differences in the ability to tolerate intercropping with corn were demonstrated also, but this ability varied with corn planting data and with season. Cultivar responses reflected differing degrees to tolerance for limited availability of growth factors such as light and water to tolerate intercropping with simultaneously planted corn.
