Grain and stover yield and composition were determined for maize grown in soil previously fertilized annually for 8 years with potassium (K, 0 to 400 kg K/ha) and phosphorus (P, 0 to 75 kg P/ha) resulting in large differences in soil test P and K.

These data may be used to evaluate the relationship between soil test P and K concentrations and maize yield and yield components. Similarly, tissue P and K concentrations differ markedly among fertility treatments and those data may be useful in evaluating the relationship between tissue P and K concentrations and maize yield and composition.
