Figure 1
Plant height as a function of applying different fertilizers at intervals during the experiment. Each point represents the average of six repetitions. The average followed by the same letter does not differ between treatments, within a date, by the Scott-Knott test. Presenting CV = 11.25%. Regression equations: No fertilizer - ŷ = 62.60 + 0.083x; R² =0.94; Organomineral (16-06-09) - ŷ = 59.63 + 0.137x; R² =0.93; Organic fertilizer - ŷ =56.33 + 0.168x; R² =0.93; Controlled release fertilizer (14-14-14) - ŷ = 52.15 + 0.214x; R² =0.97; Mineral fertilizer with micronutrients - ŷ = 53.11 + 0.210x; R² =0.88; Mineral fertilizer NPK - ŷ = -6-2.53 + 0.166x; R² =0.91; Partial Controlled release fertilizer (18-06-18) - ŷ = 61.27 + 0.169x; R² =0.92.

Falker Chlorophyll Index A (FCI A) in the leaves of the areca palm as a function of applying different fertilizers at intervals during the experiment. Each point represents the average of six repetitions. The average followed by the same letter does not differ between treatments, within a date, by the Scott-Knott test. CV = 9.70%

Falker Chlorophyll Index B (ICF) for the leaves of the areca palm as a function of applying different fertilizers at intervals during the experiment. Each point represents the average of six repetitions. The average followed by the same letter does not differ between treatments, within a date, by the Scott-Knott test. CV = 25.98%.
