Synopsis Yield depressions of 10 to 35% in irrigated spring wheat resulted from severe soil moisture stress. Reductions were greatest when stress was imposed during or after heading. Grain yield responses to nitrogen were due largely to increased head population. There appears to be no benefit in the irrigation of spring wheat prior to the boot stage unless moisture stress as indicated by wilting or curling of leaves is observed.
