Abstarct: Occurrence of chromium, particularly chromium VI in water and soil, has created serious problems on human life and the environment. Its stabilizing in contaminated environments by various methods has been the attention of many researchers. In this regard, in order to consider the effect of organic and phosphorus fertilizers on Stabilization of chromium under the pepper cultivation, an experiment was conducted at Faculty of Agriculture, Shahrood University in the greenhouse conditions as randomized complete block design with three replications. The treatments consisted of control(C), di ammonium phosphate(AP), triple super phosphate(TP), alfalfa powder(OM), humic acid(HA), di ammonium phosphate + alfalfa powder(AP+OM), alfalfa powder + triple superphosphate(TP+OM), humic acid + ammonium phosphate(HA+AP), triple superphosphate, humic acid(TP+HA). The results showed that the accumulation of chromium VI in root radish and pepper arrangement was 34.21 and 59.11 percents more than shoot. In general, all the treatments decreased the accumulation at chromium VI in the roots at radish and pepper plants and application of combined phosphate fertilizers and organic compounds were more effective when compared to the control. The lowest accumulation of chromium VI in roots were founded in the treatments TP + HA and AP + HA at the rate of 57.8 and 39.38 percents relative to the control in the shoots of radish and pepper, Respectively. alfalfa powder (OM) decreased the Concentration of chromium VI in shoots at pepper by 45.09 percent compared to the control. A negative correlation was observed between soluble phosphorus and chromium VI in the shoots of radish and pepper. It seems that application of phosphate fertilizers and organic compounds can decrease uptake of chromium VI by the plant.
