Effects of Potassium, Salicylic Acid and Humic Acid Applications on Seedling Emergence and Fusarium Wilt (Fusarium oxysporum f.sp. lycopersici) in Tomato
Abstract :
In this study, effects of potassium, salicylic and humic acid applications on seedling emergence and fusarium wilt (Fusarium oxysporum f. sp. lycopersici) in tomato were investigated under a controlled growth condition. Two different doses of potassium (K) (0 and 200 ppm), salicylic acid (SA) (0 and 0.1 mmol) and humic acid (0 and 200 ppm) were applied into fusarium inoculated soil in pots. The lowest disease severities were obtained from SA (40.3%) and HA (40.7%) treatments compared to Fusarium control (F) plants. The highest germination rates of seedlings were determined in HA, sterile control (C) and SA treatments as 80%, 77.7% and 71% respectively. Mean times of germination also were found in SA, KSA and F treatments higher as 11.4, 8.17 and 6.63 day respectively. Generally SA and HA treatments decreased the disease severity, and positively effected emergence and growth of seedling in tomato.
