| Yield potential must be determined within a diversity of production environments to evaluate a maize (Zea mays L.) genotype. A leafy (914Lfy x 957Lfy) and a normal (Funks G4507) maize hybrid were evaluated over a series of planting dates and moisture levels. A significant hybrid x planting date interaction indicated grain yield was 6.1, 17.4, and 35.4% greater for the normal hybrid than for the leafy hybrid across the early, medium, and late planting dates, respectively. An interaction with year was also detected for both planting date and hybrid. Reduced yields were attributed to increased plant barrenness and decreased kernels ear... |
