Abstract
In many California orchards, expected yields of hedgerow plantings of `Chandler' ( Juglans regia ) walnuts have fallen below grower expectations. This study compared crop yields following 2-, 3-, and 4-year hedging intervals. Results indicate an incremental yield increase when `Chandler' trees are hedged on a 3-year rather than the standard alternate-year hedging rotation. Extending the hedging interval beyond 3 years shows little advantage and possible long-term negative consequences as a result of prolonged shading and loss of spurs in the interior canopy.
