Season and Nitrogen Fertilization Effects on Yield and Physicochemical Attributes of Strawberry under Subtropical Climate Conditions

Strawberry (Fragaria ×ananassa Duch.) yields in winter production regions are greatly affected by early-season nitrogen (N) fertilization, especially when pre-plant N is not applied. In Florida, United States, applying at high rates during the early season a common fertilization practice, but little known about its impact on fruit quality. The objective of this study was to examine and effects yield physicochemical attributes ‘Florida Radiance’ strawberry grown under subtropical climate conditions. Field experiments were conducted west-central Florida over two growing seasons. Plants treated with three (1.12, 1.68, 2.24 kg/ha/d) 21 days vegetative growth stage. Thereafter, all plants same rate 1.12 kg/ha/d until end season. Increasing increased marketable 15% 18%, it had no significant effect any quality attributes. Contrarily, similar both seasons, whereas showed remarkable seasonal variations. higher solar radiation lower temperature, RH, rainfall development period, berries redder anthocyanin accumulation pH, acidity, soluble solids. These results suggest that has greater than which complex dissect because interaction between environmental use appears be an effective strategy improve profitability production. Importantly, technique minimal risk compromising or fertilizer efficiency.
