Abstract
Disodium manganous ethylenediamine tetraacetate (MnEDTA), applied to the soil with 113 and 227 g sodium ferric ethylenediamine di-(o-hydroxyphenylacetate) (FeEDDHA), increased the concentration of Mn and reduced the concentration of Fe in ‘July Elberta’ peach leaves (Prunus persica (L) Batsch). Both rates of the Fe chelate increased Fe and reduced Mn and K in the leaves when compared to non-treated ones. Both rates of the Fe chelate reduced Fe chlorosis and increased shoot growth and size and yield of fruit. Mangenase chelate with 113 g Fe chelate reduced N in the leaves and increased trunk growth. Manganese chelate with 227 g Fe chelate reduced P in leaves. The Zn content in leaves, size of fruit, leaf chlorosis, trunk and shoot growth were not affected by Mn chelate applied with Fe chelate.Keywords
