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