In order to investigation the effect of Mangnese, copper and magnesium on yield and quality of Valencia orange an expriment was conductcd as Randomize completed. Block design (RCBD) with 8 treatments and 3 replications that every plot contained 3 10-15 year valancia orange trees. Foliar spray was done in appropriated concentrations in fcbruary, May and March. Resalts showed that combinded treatment of foliar spray of manganese sulfate (0.22%) and magnesium sulfate (0.1%) with one week intervals has the greatest effect on yield in comparison with check. Also the yield in this treat ment and check was 31.3 and 18.3 t/ha respectively. Simple foliar spray of mangnesum sulfate and copper sulfate together increased the yield but not significantly. The least yield was related to the use of manganese sulfate and magnesium sulfate and copper sulfate together.
