ABSTRACT

Six potassium treatment combinations were evaluated. Treatments were twenty-five pounds of K applied preplant and a control. Foliar application of five pounds K at first square, five pounds K at first square + seven days, and no foliar K were evaluated in both combinations of preplant fertilizer. The results supported the soil test recommendation of twenty-five pounds of potassium per acre. The data did not support the foliar application of potassium. The varieties responded as expected.
