The goal of this work is to study the effect of the Natural Plant Complex (NPC) “White Pearl” on the yield and marketability of apples after long-term storage. The experiment comprised the following treatments: 1—control (without treatment); 2—foliar sprays (1% solution of “White Pearl Universal (WPU) Antifreeze” + 1% solution of “White Pearl (WP) Drip Ca + Mg”); and 3—foliar sprays (3% solution of “WPU Antifreeze” + 3% solution of “WP Drip Ca + Mg”). Foliar sprays with organomineral fertilizers (1% solution of “WPU Antifreeze” + 1% solution of “WP Drip Ca + Mg”) significantly increased (by 1.8 times) the yield of the experimental apple cultivar compared to the control. After long-term storage, foliar sprays with a 1% solution and 3% solution of NPC “White Pearl” preparations significantly reduced scald damage to ‘Sinap Orlovsky’ apples compared to the control and increased the number of marketable ‘Sinap Orlovsky’ fruits by 1.4 and 1.2 times, respectively, but the 1% solution of organomineral fertilizers was more effective. The experiment that was conducted to evaluate the effect of organomineral fertilizers in apple plantations shows that they can potentially be used to supplement traditional apple cultivation technologies.
