Synopsis Yield increases from P fertilization of dryland spring wheat were influenced by available soil P, soil moisture, and precipitation. Yield increases on medium P soils were directly proportional to the amount of moisture available at seeding and to the sum of seeding time moisture plus precipitation from tillering to heading. On relatively high or low P soils the availability of soil P largely determined how P applications affected yield increases.
