Tomatoes grown in water cultures, in the presence of sodium arsenite, accumulated less arsenic in the fruits than in the leaves and stems. The total yield (fruits, stems, and leaves) was markedly and progressively reduced by arsenic, even the most dilute concentration - 1/2 part per million - reducing the yield by 20 percent. Arsenic toxicity in the tomato was partially dependent on phosphate availability. As the phosphorus level was increased, within certain limits, the plant survived greater concentrations and absorbed less arsenic. In repeated croppings, less arsenic was accumulated in the tops of each plant, but the roots continued to absorb large quantities.
