Abstract

Three corn cultivars (Zea Mays L.) were planted at different population densities and examined for number of days to mid-silk, plant height, and grain yield. Both plant height and grain yield differed between the two years. The local cultivar reached the mid-silk stage later and out yielded the other two cron cultivars. Grain yield was found to increase with population density. These results suggest that additional research should be conducted with population densities above 50,000 plants per hectare.
