The pot experiment was established in vegetation cage of Department of Agrochemistry and Plant Nutrition. It consisted of four treatments: a control variant (K) a variant fertilized with a coated fertilizer (DC) a variant fertilized with a conventional fertilizer (DE) and the variant fertilized with coated fertilizer with micronutrients (DCm), It follows from achieved results that polymer coated fertilizers with and without microelements showed a better effect to each monitored parameters than conventional fertilizer. In comparison with control, application of polymer coated fertilizers increased the production of above-ground fytomass 3-3.5 times. The conventional fertilizer increased the aboveground fytomass production 2.2 times in comparison with control. The coated fertilizers in comparison with conventional fertilizer increased aboveground fytomass production by 49% (DC) and 60% (DCm). The production of roots was also well stimulated by fertilizing. In comparison with control, the polymer coated fertilizers increased the root production 2.9 (DC) and 3.4 (DCm) times. Conventional fertilizer in comparison with control treatment increased the root production 2.2 times. The polymer coated fertilizers in comparison with conventional fertilizer increased the root production by 30% (DC) and 52% (DCm). The yield of fruit was higher, when plant were fertilized with coated fertilizers. Polymer coated fertilizers stimulated the production of fruit and the yield was 2.4 (DC) and 3.6 (DCm) times higher than control treatment. Con ventionai fertilizer increased the fruit yield of stra wber-ry 2.1 times in comparison with control. Polymer coated fertilizers increased the yield production by 65% (DCm) and 10% (DC) comparing with conventional fertilizer.
