Improving irrigation efficiencies in pears case studies

Hot summers and cork spot in d Anjou pear can be a significant challenge in central Washington. Cork spot is responsible for an estimated $7 to $8 million dollars in losses to d Anjou production every year. For example, in 2017 cork spot accounted for approximately one-third of d Anjou culls at three major packinghouses. Irrigation frequency and timing as well as good calcium programs can affect tree growth, productivity, and fruit quality in pears. Fruit size is also critical for high returns. The following case studies illustrate common irrigation system challenges in Washington pear orchards and the results of system upgrades designed to address site specific challenges. These case studies are designed to provide growers with potential solutions to common irrigation challenges in order to improve fruit quality and profitability
