Abstract
The results of studies on the joint application of foliar feeding of Apple trees with the main fertilizer, its influence on the content of certain components of the chemical composition of the fruit of different varieties of Apple. The application of nitrogen fertilizers in the soil (N30 and N60 and N90) as part of complete mineral fertilizer contributed to a significant increase in the content of dry substances in fruit varieties Idared 0.9; 1.8 and 1.4 percent. A similar pattern was observed when using non-root fertilization (N10, N20 and N30) and for the introduction of relevant standards foliar system on the background of RK. Joint application of fertilizers in the soil with foliar feeding only in plantations varieties Idared had a significant impact on the chemical composition of fruits. Increase the content of dry substances from the combined introduction of single doses of nitrogen in the soil with different standards when foliar feeding amounted to 1.4-2.3 percent. In combination with double and triple standards foliar increased the content of dry soluble substances by 1.1-2.5 and 1,6-2,0 %.
