Abstract
The effects of plant density on leaf number and some developmental events in four corn hybrids were studied in 1969 and 1970. Increase in plant density was accompanied by a decrease in leaf number, an increase in the periods from planting to tassel emergence and mid-silk, and an increase in grain moisture at harvest. High linear correlations between leaf number and these developmental events were obtained within the spacing environments. The effects of eight planting dates on leaf number and some developmental events were studied in 1970. Delayed planting was accompanied by changes in leaf number, with a significant increase in leaf number at the middle planting dates, a decrease in the periods from planting to tassel emergence and mid-silk, and an increase in grain moisture at harvest. Leaf number was highly significantly correlated with these developmental events within the planting date environments.
