Interpretive Summary:

Technical Abstract: Date production requires high temperatures and abundant water for commercial production. Commercial date production in the United States is confined to the low desert areas of California and Arizona. Estimations of water requirements for date production were made decades ago under flood irrigated conditions. Recent studies of micro-irrigated and flood irrigated dates produced in updated crop coefficients and irrigation guidelines. Actual crop consumptive water use varies with soil conditions, especially salinity, and canopy cover and tree height. Irrigation requirements are greater in soils with saline or sodic characteristics. A hybrid micro-irrigation/flood irrigation regime is suggested, as micro-irrigation systems may not be capable of supplying sufficient water during high water demand months. Monitoring of soil water potential of the upper 1 - 2 feet of the soil profile is a useful tool in assessing soil water availability in date production.
