Abstract

To evaluate the effect of different levels of nitrogen and iron on some quality indices and yield parameters of ‘ Granny Smith’ apple a factorial experiment, in a completely randomized block design with three levels of nitrogen (0, 144 and 288 g Ammonium nitrate per tree( and three levels of iron (0, 1500 and 3000 mg Fe-EDDHA per tree) as soil application, was conducted during 2015. Nitrogen application increased chlorophyll index and yield efficiency. The highest chlorophyll index (58. 77) and yield efficiency (0. 889 Kg. m ) were observed in 288 g/tree Ammonium nitrate. Iron application increased pH of fruit juice and fruit iron concentration, and decreased leaf K concentration. Positive correlation between total antioxidants and leaf Fe concentration (r = 0. 84), a* parameter and leaf Fe concentration (r = 0. 68), leaf K content and leaf N content (r = 0. 69), fruit K content and fruit N content (r = 0. 74), leaf N and fruit N content (r = 0. 66) was observed. In conclusion, nitrogen application at 288 g/tree was more effective in improving the mentioned characteristics. Iron nutrition had no much impact and seems that more concentrations of iron are required to a greater effect.
