Synopsis Planting dates had small effects on the numbers, sizes, rate of emergence, and longevity of corn leaves. There were differences among hybrids in the numbers, sizes, rates of emergence, and longevity of leaves. Longer‐season (later) hybrids developed and maintained larger leaf areas per plant than the shorter‐season hybrids. Increasing the availability of nutrients, particularly of N, early in the season generally increased the numbers of leaves formed per plant, increased the sizes of leaves more consistently than the numbers, and increased the rates of leaf emergence and leaf area expansion.
