Irrigation of Grain Sorghum on the Delmarva Peninsulaby W. F. Ritter, (M.ASCE),
R. W. Scarborough,
Abstract: Irrigated grain sorghum experiments were conducted for two years on a Norfolk sandy loam soil. Full irrigation was compared to partial irrigation and no irrigation in a randomized block design experiment. In one out of the two years, grain sorghum showed a significant response to irrigation. The full irrigation treatment yielded 7555 kg/ha, while partial irrigation and no irrigation yields were 7377 and 6329 kg/ha. Seasonal ET rates for the full irrigation treatment were 413 mm in 1990 and 477 mm in 1992.
