Synopsis The ratio of ears produced to mature plants was the major contributor to increased yields which resulted from drilled over hill‐dropped and checked corn grown under irrigated conditions in Nebraska. Although this ratio decreased with increasing population, the greater number of ears per acre accounts for much of the grain yield increase when planting rates were increased. Components of yield were linearly correlated with population but not with yield due to the curvilinear relationship of yield to population.
