Description
Summary:Fruit cracking is one of the most important obstacles facing pomegranate cultivation, which inflicts great damage on the crop, sometimes reaching more than 70%. The research was carried out in the 2018 agricultural season in a field planted with pomegranate trees (French variety) in order to study the effect of foliar spraying with zinc in reducing fruit cracking. The experiment was conducted according to a complete randomized design (CRD). We had three treatments for zinc concentrations (0, 500, 1000 ppm) and four treatments for the number of spraying times (0, 1, 2, and 3 times). The results showed the superiority of all treatments of spraying with zinc over the control treatment in most of the studied traits. Also, increasing the number of spraying times with zinc reduced the percentage of fruit cracking, as the percentage of cracked fruits reached 73.96%, 21.48%, 15.91%, and 12.72% in the treatments of 0, 1, 2, and 3 spraying times respectively. Similarly, the increase in the spraying concentration achieved a significant reduction in the percentage of fruit cracking, which amounted to 17.10% and 14.43% in the treatments of concentrations A and B, respectively.
