| To evaluate the effect of the fertilizer concentration after flowering on growth a31d fruit setting of ornamental pepper (Capsicum annuum L.), plants were fertilized with $100;mg{cdot}L^{-1} of N ($EC=0.8;dS{cdot}m^{-1}) until flowering, and then with 0 (no fertilizer), 100, 200 or $300;mg{cdot}L^{-1} of N (fertilizer solution EC of 0.15, 0.8, 1.45 or $2.10;dS{cdot}m^{-1}, respectively) until harvest. Maximum leaf area and shoot dry mass at the end of the growing period were obtained when plants were fertilized with $200;mg{cdot}L^{-1} of N. Total fruit number per plant at the end of the growing period was not different when plants were fertilized with 100,200 or 300 mg{cdot}L^{-1}of N concentration. When plants were fertilized with $200;mg{cdot}L^{-1} of N, the number of fruits per plant was decreased significantly as compared to 100, 200 or $300;mg{cdot}L^{-1} of N, whereas the percentage of red fruits at the end of the growing period was maximized. Total fruit fresh weight per plant at the end of the growing period was highest with the concentration of $200;mg{cdot}L^{-1} of N. The EC of the growing medium remained within 0.8 to $1.2;dS{cdot}m^{-1};2.0;to;3.0dS{cdot}m^{-1}, or 3.0 to 4.5 dS{cdot}m^{-1}when fertilizer concentrations were 100, 200 or $300;mg{cdot}L^{-1} of N, respectively. Throughout most of the experiment, the pH of the growing medium remained within 5.4 to 6.2, but dropped to 4.9 near the end of the experiment when fertilizer concentration was 200 or 300;mg{cdot}L^{-1} of N. Content of most of the nutrients In the leaf was not affected by the different fertilizer concentration. Only aluminum was significantly affected and decreased linearly with increasing fertilizer concentration. The results from this study indicated that optimal fertilizer concentration after flowering for commercial production of ornamental pepper was 100 or $200;mg{cdot}L^{-1} of N. At these concentrations, the EC of the growing medium remained approximately within 0.8 to 1.2 and 2 to $3;dS{cdot}m^{-1}, respectively. This appears to be the optimal range for vegetative growth or fruit setting of ornamental pepper plants, and indicates that ornamental pepper can be grown with a fairly wide range of fertilizer concentrations. |
