Reduction of Lime-Based Iron Chlorosis in Apple Trees

Objective: This study was conductud with the aim of determining effects different applications (Fe fertilizers, K-Humate, and sulfur) on shoot length, active total Fe, chlorophyll a, b, a+b, fruit Fe concentration, yield efficiency, apple.
 Materials Methods: In study, which conducted in 4 replications according to trial pattern chance blocks an apple orchard a lot lime alkaline reactions,13 (Control, FeSO4.7H2O (19% Fe), Elemental S, + Fe-EDTA (%13 Fe-DTPA (%6 Fe-HBED Fe-EDDHA (o-o:2.2) (o-o:3.5) (o-o:4.8) (o-o:5.25) Fe)].
 Results: As result investigated parameters were found be statistically significant, maximum effect determined by FeSO4.7H2O+K-Humate (o-o: 5.25) applications. Since there is no difference between these applications, or Fe-chelate fertilizers can used instead FeSO4.7H2O+K-Humat.
 Conclusion: addition, it has been that iron intake plants increased as ortho-ortho isomer ratios increase fertilizers. It applying 5.25), one more effective than other reducing eliminating chlorosis calcareous soils.
