Abstract
Experiments were conducted to investigate the effects of applications of N, P, K, B and dolomitic limestone on yields of strawberry (Fragaria × ananassa Duch ’Redcoat’). Yields were increased by applied N and P, but were not affected by added potassium or boron. Second crop yields were increased by a greater extent than first crop yields by both N and P. First crop yields were increased by a pre-planting application of dolomitic limestone on a sandy loam soil with initial pH of 4.9. Leaf tissue concentrations at full bloom of 1.4–3.2% N, 0.17 to 0.34% P, 0.7 to 1.6% K, and 26–57 ppm B appear to be in the sufficiency range for the cultivar Redcoat. The concentrations of these elements in strawberry leaf tissue were lower after harvest than at full bloom.Key words: Strawberry fertility, leaf tissue concentration
