Effects of nitrogen, phosphorus, potassium and calcium nutrition on strawberry anthracnose
Plant Pathology 55 (2), 246-249
Abstract: The effects of a range of concentrations of four nutrients - nitrogen, phosphorus, potassium and calcium - in fertilizer solutions on the severity of anthracnose on strawberry cv. Nyoho cultivated under a noncirculation hydroponics system were determined after inoculation with Colletotrichum gloeosporioides. Crop growth and tissue nitrogen, phosphorus, potassium and calcium contents of the entire above-ground parts of the plant were also investigated. Elevated nitrogen and potassium concentrations in the fertilizer solution increased disease severity in contrast to phosphorus and calcium. Treatment with either NH₄ or NO₃ nitrogen was not significantly different. The dry weight of the strawberry plants increased significantly with elevated concentrations of nitrogen (R2 = 0·9078) and phosphorus (R2 = 0·8842), but was not influenced by the elevated amounts of potassium (R2 = 0·8587) and calcium (R2 = 0·6526) concentrations.
