Also, relationships between total phosphorus, calcium, iron, zinc and active Fe (in the fresh leaf), Zn (in the fresh and dry leaf) contents of loquat leaves were investigated. Leaf samples were obtained from 4 orchards in Tarsus district of Icel province. Leaf samples were regularly taken every two weeks from September to May during both years. There were positive significant relationships between nitrogen and potassium contents of leaves and yield. While positive significant relationships was observed between total Fe and active Fe, significantly negative relationships were determined between total Zn and active Zn. Keywords :
