Pot experiment was conducted to test the effect of iron plaque on rice yield and arsenic and other elements uptake and translocation in different parts of rice plants. For iron plaque formation (25, 50 and 100 mg Fe L-1 solution) on rice root and As enriched soil (33 mg As kg-1) were used. The treatment combinations were As0Fe0, As33Fe0, As33Fe25, As33Fe50, and As33Fe100. Experiment was laid out in a complete randomized design with three replications. Results revealed that the highest plant height and panicle length (76cm and 22.33cm), filled grain, total grain and total tiller (77.33, 83.33, 19.00), root volume (24.00 cm3/plant), root weight and 100 seed weight (1.86 and 1.83 g/plant) were found in As0Fe0 treated plots, respectively. Maximum non-effective tiller (2.67) was found in As33Fe50 treated plots. The highest grain yield was obtained from As0Fe0 followed by As33Fe25 treatment. Phosphorus inhibited by all treatments except grain in As33Fe0 and control. Significant Zn uptake was found in control treatment. From these results it may be concluded that iron plaque on root using 25ppm Fe is an effective technology to inhibit the accumulation and translocation of arsenic and Cd from root to other parts of rice plants.
