Abstract

In this research, 2 different doses of acetic acid (AA: 4%, 40%) were treated the seed before sowing; 2 different doses of humic acid (HA1 :2 L da-1 , HA2 :6 L da-1) and nitrogen (N: 5 kg da-1) treatments to the plant in the field were carried out in Strip-Plots Design in Samsun ecological conditions to determine the effects of faba bean agro-morphological, seed quality and L-DOPA content in flowers. According to the findings obtained, ıt was determined that the seed treatment had a statistically significant effect on the number of branches, pods, biological yield, seed yield and flower yield, and the 4% AA treatment gave better results compared to the control. HA and N as plant treatments showed a statistically significant and negative effect on the number of pods, biological yield and seed yield. The statistical effects of the treatments on the L-DOPA transferred to the herbal tea obtained from the flower were not found significant. However, it was determined that the AA treatment to the seed increased the ratio of L-DOPA in flower compared to the control. Therewithal, when the ratio of flowers was increased from 100 mg to 200 mg while preparing tea, there was an increase in the ratio of L-DOPA transferred to the tea water.
