摘要

FAYETTEVILLE, Ark. A healthy dose of nitrogen fertilizer can coax top yields from rice, but cross the optimum line and diseases can set the crop hack and cost producers more than they gain, say University of Arkansas Division of Agriculture scientists. This interaction with nitrogen fertilizer is true for almost all rice diseases, but it has been seen most commonly with sheath blight, kernel smut and blast, said Dr. Nathan Slaton, director of the Arkansas soil testing and research program. Dr. Rick Cartwright, Extension plant pathologist, said sheath blight is the number one concern with excessive nitrogen. "When there,s more nitrogen than is needed for maximum yield, sheath blight goes wild," he said.
