Özet

This study was conducted to investigate the effects of different phosphorus and potassium doses on yield and amino acid composition of Uygar F1 capia pepper (Capsicum annum) cultivar. In addition to soil available quantities, 5 different potassium doses (0, 1, 2, 4 and 8 kg K2O da(-1)) and 3 different phosphorus doses (0, 5 and 10 kg P2O5 da(-1)) were applied in 3 replications under greenhouse conditions. The greatest yield (4812.11 kg da(-1)) was obtained from 4 kg da(-1) K2O + 5kg da(-1) P2O5 treatments and 75.85% increase was achieved in yield as compared to the control treatment (0 kg K2O + 0 kg P2O5). The greatest number of fruits per plant (21.77 fruits plant(-1)) was also obtained from 4 kg da(-1) K2O + 5kg da(-1) P2O5 treatments. According to results phosphorus and potassium play a great role yield and amino acid composition of capia pepper. But greater phosphorus and potassium doses increased amino acid quantities, but reduced yields.
