Abstract

Grain sorghum was planted to a uniform stand on Cecil sandy loam soil which had been fertilized with 408 kg/ha of a 4.0-5.3-10.0 (4-12-12) fertilizer. The plants were sidedressed with 56 kg/ha of nitrogen. Heads were harvested and threshed from 1-row plots 1.52 m long. Yields from these plots were combined in various combinations of rows and row lengths to determine the optimum plot size as measured by coefficients of variation.Data from this 3-year study involving different size and shape of plots for grain sorghum indicated that the optimum size plot consisted of 2 rows 4.56 m (15 ft) long.
