Abstract: This paper report on a hydroponics experiment that was conducted to investigate the effect of Molybdenum (Mo) and Sulphur (S) on As-V and As-III accumulation within the seedling of the rice cultivar IET-4786 (Shatabdi). The seedling were subjected to four concentration of Mo and S, i.e. full Hoagland solution (CH), Hoagland solution with high Mo and S, Hoagland solution with low Mo and S and Hoagland solution with Mo and S deficient with As-V and As-III contamination along with CH as a control treatment. Analysis of Mo, S and As species of the leaves and root of seedling indicated that uptake of As-V and As-III was significantly affected by both Mo and S. Mo nutrition make some complex with As in solution and prevent As entry in to the plant system. S in the form of sulphate nutrition plays an important role in regulating arsenic translocation from roots to leaves and arsenic translocation from roots to shoots was enhanced by sulphur deprivation.
