Abstract :Objective: This study was conductud with the aim of determining the effects of different applications insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(Control, FeSO4.7H2O insert ignore into journalissuearticles values(19% Fe);, Elemental S, FeSO4.7H2O + Elemental S, K-Humate, FeSO4.7H2O + K-Humate, Fe-EDTA insert ignore into journalissuearticles values(%13 Fe);, Fe-DTPA insert ignore into journalissuearticles values(%6 Fe);, Fe-HBED insert ignore into journalissuearticles values(%6 Fe);, Fe-EDDHA insert ignore into journalissuearticles values(o-o:2.2); insert ignore into journalissuearticles values(%6 Fe);, Fe-EDDHA insert ignore into journalissuearticles values(o-o:3.5); insert ignore into journalissuearticles values(%6 Fe);, Fe-EDDHA insert ignore into journalissuearticles values(o-o:4.8); insert ignore into journalissuearticles values(%6 Fe);, and Fe-EDDHA insert ignore into journalissuearticles values(o-o:5.25); insert ignore into journalissuearticles values(%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 insert ignore into journalissuearticles values(o-o: 5.25); applications. Since there is no difference between these applications, Fe-EDDHA insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(o-o: 5.25);, one of the Fe-chelate fertilizers, is more effective than other applications in reducing and eliminating chlorosis in calcareous soils.
