Abstract: 

Considering the calcareous soil of pistachio orchards in Iran and high EC and pH of soil, Fe acquisition by pistachio trees from the soil is difficult and cause chlorosis in pistachio trees. When soil condition is not suitable, foliar application of mineral nutrients for nutrient provision of deficit plants is more effective than soil application. This experiment was done for investigation of foliar application of chelated Fe on ecophysiological characteristics of four economical cultivars of Iranian pistachio (‘Ohadi’, ‘Ahmadaghaii’, ‘Akbari’, and ‘Kalehghoochi’) on ‘Badamie Rize Zarandi’ rootstocks. Foliar application of Fe at 0.5 and 1 g 1-1 increased photosynthesis, transpiration, and water use efficiency compared to control, and the highest photosynthesis was at 1 g 1-1 and cv. ‘Kalehghoochi’ in which leaf Fe concentration was 3 time higher compared to control. It was concluded that foliar application of chelated Fe can solve Fe deficiency and has suitable effects on photosynthesis of pistachio trees.
