520			_aTwelve corn (Zea mays L.) hybrids and selections were evaluated for yield and other plant characters at densities of 45,000 and 90, 000 plants/ha. The study showed no yield advantage when densifies were increased to 90, 000 plants/ha. Significant differences among entries were observed in time to midsilk, ear height, plant height, test weight, weight of 1000 kernels, rust severity, and yield. No population-density X entry interaction for these characters was observed. Significant differences between population densities and among entries were observed in diameter of the third internode and number of ears per plot. Hybrid Pioneer 304C had the highest yield;
