Abstract

Nephrolepsis exaltata (L.) Schott cv. Rooseveltii was grown with 3 fertilizer rates (50, 150, and 300 ppm N) applied as 20N-8.7P-16.7K fertilizer at 3 frequencies (1, 2, and 3 times weekly). Plant dry weight and frond number were similar for ferns receiving 150 ppm N, 2 or 3 times weekly, and 300 ppm N, 3 times weekly. Ferns treated with 300 ppm N, 2 or 3 times a week, had a greater concentration of tissue N and were greener than ferns treated with 150 ppm N, 2 or 3 times weekly, or ferns treated with 300 ppm N, once weekly. P and K tissue concentrations were similar for all treatments with the exception of ferns treated with 50 ppm N.
