Study of the Effect of Organomineral Fertilizers on the Yield and Quality of Apples After Long-Term Storage

The goal of the 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. Experiment options: 1 – control (without treatment); 2 – foliar sprays (1% solution " White Pearl Universal (WPU) Antifreeze" + 1% solution " White Pearl (WP) Drip Ca + Mg"); 3 – foliar sprays (3% solution "WPU Antifreeze" + 3% solution "WP Drip Ca + Mg"). Foliar sprays with organomineral fertilizers (1% solution "WPU Antifreeze" + 1% solution "WP Drip Ca + Mg") significantly by 1.8 times increased the yield of the experimental apple cultivar compared to the control. Foliar sprays with 1% solution and 3% solution of NPC "White Pearl" preparations significantly reduced the damage of ‘Sinap Orlovsky’ apple fruits by scald compared with the control during the prolonged storage. The number of marketable fruits of ‘Sinap Orlovsky’ during the long-term storage was increased by 1.4 and 1.2 times, but it should be noted that the 1% concentration of the solution of organomineral fertilizers was more effective. The conducted tests of organomineral fertilizers in apple plantations show the prospects of their use as additional techniques in traditional apple cultivation technologies.
