Planting Dates and Transplant Establishment Methods on Early-yield Strawberry in West-central Florida

摘要

Earlier fall planting dates for strawberry (Fragaria xananassa) in west-central Florida tend to promote earlier onset of flowering and fruiting. However, warm air temperatures (&28 degrees C) can result in excessive growth and runner production. Sprinkler irrigation is a common practice to reduce air temperature in the first 10 to15 days after transplanting, requiring large volumes of irrigation water. An alternative to sprinkler irrigation is the application of crop protectants such as kaolin clay after transplanting. The objectives of this study were to determine the optimal planting dates and to assess the most appropriate establishment practices for strawberry bare-root transplants in Florida. Four establishment practices-10 days of sprinkler irrigation (DSI), 10 DSI + kaolin clay, 7 DSI, and 7 DSI + kaolin clay were evaluated for 'Florida Radiance' and Sweet Sensation (R) 'Florida127' transplanted in mid September, late September, and early October in consecutive seasons. For 'Florida127', September planting dates increased early yield compared with early-October traditional planting dates, with no difference in total yield. Seven DSI followed by the foliar application of kaolin clay at day 8 was also found to increase early yield compared with 10 DSI for strawberry establishment, with annual water savings of 108.7 mm.
