Abstract

Three experiments were conducted at Manhattan, Kansas, from 1962 to 1964 to determine the extent plant height affected response to row width and stand density in three grain sorghum varieties. The experimental lines were isogenic differing by one gene (Dw3) and thus allowed the height effect to be determined within a common genetic background. Tall and short types averaged 57 and 37 inches, respectively, when mature.Mean yield from 20-inch rows exceeded that from 40-inch rows by 502 pounds per acre, or 11%. There was little evidence for a row width by plant height interaction. However, plant height by stand density and plant height .by variety interactions were significant in each trial. The short genotype (dw3) performed better at high stand density (120 square inches per plant), but the tall genotype (Dw3) was superior at lower stand densities (240 or 360 square inches per plant). The plant height by variety interaction for yield and components of yield resulted largely from Redlan, the latest.maturing variety used.
