Cadmium is one of the most important pollution agent in environment.Use of waste water in our Agriculture is nececery,because we haven't enough water for agriculture.In the other hand,there is a lot of pollution agent such Cadmium in waste water which make a lot of hazard for human and envirinmwnt.There is a lot of experience about role of Zn and K on decreasing of Cd in plant.This study was conducted to determination of K and Zn effects on Cadmium uptake by wheat and effects on other parameters.The experiment design was split plot with three main plot and four subplot.main plots consisted of without potassium,use of potassium base on soil test recommendation and use of potassium tow more time more than soil test recommendation.Subplots included of without Zn,Zn as foliar application,use of zn in soil and use of Zn as foliar and soil application.Results showed that there is a significant effects in main effects and sub effects in grain yield,biomass and ear length.there is a significant effects in sub plots only about 1000seed weight and number of seed per ear.Use of potassium increased grain yield ,straw and ear length,but there is not any significant effects between use of potassium base on soil test recommendation and two more time more than soil test recommendation.Cadmium concentration in seds affected by Zn and k application.Maximum seed cadmium concentration was related to use of foliar applicartion of Zn and soil application with use of Potassium.
