Influence of fertilization with zinc products on the productivity and quality of apple fruits

Abstract

The study subject of the experience was Idared apple variety grafted on M 9,trees were trained as Slender Spindlesfordistance 3.5 x 0.8m. To study the influence of fertilization with zinc products on the fructification of apple plantationwas experimented the following variants: 1. Control–no treatment; 2.Basfoliar Flo Zn-1.0L/ha; 3. Nertus Zinc-2.0L/ha;4. Nertus Zinc -3.0 L/ha. The Basfoliar Flo Zn fertilizer was applied once by spraying in the intensive growth phase of the fruit. The first treatment with Nertus Zinc was given in the pink button phase, the second -after flowering, and the third -the intensive growth of the fruits.The research was conducted during the period of 2015year. In the present research work, we demonstrated that Nertus Zinc may be included in the technology system, applied 3 sprays at 2.0 L/ha.
