Chromium due to environmental toxicity is considered as an environmental dangerous pollutant. Bioaccumulation of this metal has been harmful to living organisms. Cr also causes deleterious effects on plant physiological processes such as photosynthesis, water relations and mineral nutrition. In this regard, in order to investigate the effect of phosphorus and organic fertilisers on some growth properties of radish irrigated with chromium- contaminated water, an experiment was conducted at Faculty of Agriculture, Shahrood University in the greenhouse conditions as randomised complete block design with three replications in 2015. The treatments were: control, di ammonium phosphate, triple super phosphate, alfalfa powder, humic acid, di ammonium phosphate + alfalfa powder, alfalfa powder + triple superphosphate, humic acid + di ammonium phosphate, triple super phosphate, humic acid. Analysis of variance revealed significant differences (p $\leq$ 0/01) among treatment on height and leaf chlorophyll content. But there was no significant difference among treatments in fresh and dry weight of plant. Mean comparison of treatments showed that the combination use of phosphorus fertilisers with alfalfa powder or humic acid increased the height and leaf chlorophyll content. The maximum height and leaf chlorophyll was observed in combined use of humic acid + di ammonium phosphate. The combined appliacation humic acid + di ammonium phosphate increased height and leaf chlorophyll content by 29.28 and 30.32 percent in comparison to control treatment. Based on the results of this expriment, combined appliacation of phosphate fertilisers with organic fertilisers can decrease toxicity of chromium in the radish, ultimately resulted in improvement plant parameters.}
