Özet:

In this study, the effect of potassium sulfate (K2SO4) fertilizer applied at different doses from leaves (1%, 2%, 3%) and soil (5-10-20 kg/da) on yield and quality was investigated under high-temperature stress. The experiment was established according to the randomized plot design, each application consisted of 3 replications. As a result of the experiment, it was determined that potassium applications had a significant effect on the control and stress plots. It was concluded that potassium applications increased fruit berry weight, fruit size and diameter, and fruit flesh thickness under stress conditions. Especially under foliar application of potassium sulfate stress conditions; It was concluded that fruit number, fruit grain weight, fruit volume, and fruit flesh thickness increased. It was determined that potassium applications positively affected the N, P, K, Ca, Mg, Cu, and Fe concentrations of the fruits in the control and stress parcels.
