      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.},
