Routine summer maximum105°F
Annual irrigation2.0–3.0 acre-feet/acre
Mature yield8000–11000 lb/acre

Planning values describe productive plantings, not absolute survival limits. Local evapotranspiration, soil, cultivar, plant age, rainfall, and management can materially change them.

Spring10–20
Summer26–34
Fall10–20

Daily-equivalent demand is useful for system sizing; actual irrigation may be accumulated into less-frequent, deeper applications.

Why it belongs

Mission is among the more cold-tolerant traditional California olives. It can produce a concentrated, shelf-stable product and can be managed with regulated deficit irrigation, making it one of the strongest candidates for warm high-desert agriculture.

Hot/cold sites such as Bishop and Kingman should be treated as selection environments rather than assumed commercial orchard locations.

Trial priorities

  • Compare full and regulated-deficit irrigation for oil yield and quality.
  • Select Mission-derived material for winter hardiness and earlier maturation.
  • Evaluate slope, cold-air drainage, salinity, and alkaline-soil effects.
