Nondamaged corn ( Zea mays L.) plants yielded significantly more (about 8,500 kg/ha) than plants in the same field showing six or more damaged leaves per plant (about 6,000 kg/ha) as a result of a frost on June 23, 1972. No plants in any of the plots were killed. Kernel weights were 69 (nondamaged) and 61 (damaged) g/200 kernels. Maturity was also delayed as indicated by later tasseling and higher (30%) moisture content of ears in damaged plots than in nondamaged (27%) at harvest.
