Larry Arrington, Dean Bare rooted strawberry transplants set in black polyethylene mulched beds are established by irrigating continuously for approximately 8 hours daily with overhead sprinklers for 10 to 14 days. Irrigation is provided to reduce the water stress caused by the damaged root system of the transplant, the high surface temperature of the black mulch, the high ambient air temperature, and dry weather condition usually present at time of transplanting. Without irrigation, transplants become defoliated; this results in considerable plant mortality and /or a delay in fruiting. Early yield is economically important in central Florida. Presently, 4-20 inches of water are required to establish transplants depending on conditions of transplants and weather conditions. Further urbanization of the strawberry production area in Florida is likely to lead to increased regulations on water usage. An intermittent sprinkler irrigation system may provide enough water to meet transplants needs while reducing the overall water output. In experimentation conducted at the GCREC-Dover, transplants were thoroughly moistened each day before starting irrigation cycles. The irrigation intervals (min on/ min off) tested were: 3/17, 5/25, 5/15, 10/20, 15/15, and continuous, which served as the control, the first season, and, 5/25, 5/15, 5/10, and continuous the second season. Normal irrigation was then resumed for the remainder of the season. The longer the off interval, the greater the leaves lost by the end of establishment period. Irrigation intervals of 3/17 and 5/25 increased plant mortality. Yield of strawberries were not significantly different for 5/15, 10/20, 5/10, and 15/15 intervals and the control. Table 1 shows the effect of treatments on marketable fruit yields, the reduction in water use correlates to the following: 5/15 = 75%, 10/20 and 5/15 =66%, and 15/15 = 50%. Summary In summary, Foliage should not wilt, low humidity and wind speeds greater than 10 mph accelerate leaf drying, and during the heat of the day, foliage should receive irrigation soon after drying from the previous irrigation cycle. Keen observations during the establishment period will determine
