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.
