This study was carried out to determine the effects of pre-harvest calcium applications on fruit quality and fruit cracking in "0900 Ziraat” cherry variety. For this purpose, “Codiagro Agroplant” containing 35% CaO (Calcium oxide). It has been applied to trees in different applications such as dripping from the soil and leaf + dripping from the soil and foliar spraying. In the study, fruit weight (g), fruit width (mm), fruit length (mm), fruit height (suture) (mm), seed weight (g), amount of water-soluble dry matter (TSS; %), pH and acidity (mg mL-1) values, fruit firmness , cracking ratios were investigated. In addition, fruit skin and flesh color and fruit stem color values were determined. The highest results were obtained in terms of fruit weight (8.91 g and 8.80 g respectively) in the application made only with leaves and the application made with leaves and soil. Likewise, in the application of calcium made from leaves, the fruit width is 26.73 mm; fruit length was 26.61 mm, fruit height was 24.35 mm and had the highest values. The effect of calcium applications on the (total solible solids) TSS %, pH and SSCM of the fruit was found to be statistically insignificant. The hardest fruits were obtained from foliar+soil application (5.15 N). Likewise, the least cracked fruits are in leaf+soil application (cracking index; 7.10). Calcium applications made only from leaves and leaves + soil can be recommended for higher quality fruit in cherries.
