The research was carried out in the 2018 agricultural season with the aim of studying the effect of foliar spraying with potassium on reducing the fruit cracking of pomegranate. The experiment was conducted according to the completely randomized design (CRD). We had three treatments for potassium concentrations (0, 1000, 2000 ppm) and four treatments for the number of spraying times (0, 1, 2, and 3 times). The results showed that all potassium spraying treatments exceeded the control in most of the studied characteristics. The increase in the spraying concentration achieved a significant reduction in the percentage of fruit cracking, which amounted to 22.98% and 19.75% in the treatments of concentrations A and B, respectively. The increase in the number of foliar spraying with potassium also reduced the percentage of fruit cracking, as it reached 73.96%, 28.32%, 21.03%, and 17.57% in treatments of 0, 1, 2, and 3 spraying times, respectively. Similarly, the productivity was greatly increased by the effect of potassium foliar spraying.
