Abstract

Synopsis A three‐year barley study with irrigation and nitrogen variables at Yuma, Arizona, demonstrated the importance of investigating components leading to yield such as: plants per unit area, heads per plant, seeds per head, and individual size or weight per seed. Nitrogen rate increased barley yields appreciably, predominantly by increasing heads per plant and seeds per head. Moisture utilization efficiency—pounds of grain per acre‐inch of water—was favored by higher N rates and the drier moisture regimes.
