Yields from five irrigation regimes that each applied 16 acre-inches/acre were evaluated during a simulated drought year and for the subsequent two seasons under full irrigation. Drought-year production was mildly reduced by regimes that produced smaller kernels. Much greater losses occurred in the season immediately following the drought due to reduced nut load. Applying a limited allotment of water early in the drought season proved less effective in limiting subsequent production losses than irrigating at a lower rate but for a longer period of the drought season. Avoiding severe water stress during flower bud development (August and September) is critical for subsequent bloom and fruit set.
