Walnut yield responses to nitrogen applied in spring or fall, or split between spring and fall varied in an experiment on deep alluvial Columbia soil. Leaf and twig nitrogen responded most to recently applied nitrogen. Matching the crop's rate of nitrogen removal with the nitrogen application rate and monitoring plant nutritional status with leaf analysis should contribute to economical, environmentally sound walnut orchard management.
