A polymer coating of phosphate fertilizer was evaluated for rice yield response. Three rates of phosphate fertilizer, including polymer coated and non coated, were compared to an untreated check. Net returns were calculated based on crop price and input costs. At the 25-lb-acre P_2O_5 rate the polymer coated treatments produced greater yields than equivalent non coated treatments. At higher P_2O_5 rates both polymer coated and non coated treatments produced equivalent yields. The 25-lb P_2O_5 coatedTSP treatment produced the greatest returns to producers.
