This study was carried out at Mersin University, Silifke Vocational School Research and Application. It was conducted in a greenhouse in 2022. The Flora F1 cucumber variety was used to study the effect of the application of seaweed fertilizer and wood vinegar on nutrient uptake, plant growth and yield of cucumber. Wood vinegar (WDV) was prepared in 0.5% solution, and seaweed (SW) fertilizer was applied in a dose of 5 ml dm-3. They were used alone and combined [SW+WDV(S+F)], into soil and over cucumber leaves. The SW+WDV(S+F) application produced the highest early yield (1.87 kg plant-1) and 5.38 kg plant-1 in total yield. These values ​​were 1.47 kg plant-1 and 3.83 kg plant-1 in control, respectively. Also, it was determined that the SW+WDV(S+F) application provided an increase of 50.1% in total fresh biomass and 37.5% in total dry biomass compared to the control. It was found that while the amounts of N, P, K, Fe, Mn, Cu and Zn were the lowest in the control, the SW+WDV(S+F) application resulted in the highest values. The SW+WDV(S+F) application corresponded to an increase of 28.85% in nitrogen (N), 81.08% in phosphorus (P), and 59.88% in potassium (K) compared to the control. According to the results of study, it was determined that the use of wood vinegar and seaweed ferlilizer, into the soil and over leaves, had a positive effect on plant growth, yield and nutrient aptake. This positive effect may have been due to the beneficial chemical compounds contained in the seaweed fertilizer, and the suppression of disease and harmful organisms by wood vinegar in both soil and leaves.
