Arsenic is a potential contaminant of groundwater as well as soil in many parts of the world. Elevated soil arsenic levels resulting from long-term use of arsenic contaminated ground water for irrigation may inhibit seed germination and seedling establishment of rice, the country’s main food crop. An experiment was conducted to determine response of rice (Oryza sativa L) to arsenate and arsenite stress. For this purpose seeds were treated with 0, 5, 10, 15 and 20 ppm of arsenate and arsenite solution individually. Germination percent, root, shoot and seedling length, dry weight and indices of growth showed significant (P<0.05) decrease with increase in concentration of arsenate and arsenite as compared to control. Arsenite was found to be more toxic than arsenate on germination and early growth of rice seedling.
