Bondarenko V. The crop capacity of apple-tree of variety Golden Delicious on a root-stock M9 in irrigation orchard depending on out-root addition fertilizing with magnesium and microelements in the conditions of the Right-Bank Forest-Steppe of Ukraine

Object of research - regularities of influence of out-root addition fertilizing with magnesium and microelements on a growth and crop capacity of apple-tree of variety Golden Delicious on a root-stock M9. Aim of research - to clear up of out-root addition fertilizing with solutions of magnesium and microelements on a growth and crop capacity of apple-tree in irrigation. Methods of research - field, laboratory-and field and laboratory, mathematic statistic, economic and calculation methods. Theoretical and practical results - defined to optimal concentrations of solutions of magnesium and microelements to rise crop capacity of orchard of variety Golden Delicious on a root-stock M9 in irrigation. Novelty - in the condition of unstable moisture of south part of the Right-Bank Forest-Steppe in a orchard of a winter apple on a root-stock M9 for the first time established the activity of out-root addition fertilizing with magnesium and microelements on a growth and crop capacity of apple-tree.
