Abstract
A method for increasing the yield of rice crop plants by foliar application to the plants during the plant growth stage a granular fertilizer consisting essentially of urea and ammonium sulfate in a urea/ammonium sulfate. The granular fertilizer has a urea/ammonium sulfate weight ratio of about 4/1 and contains at least 40% nitrogen and at least 4% sulfur. The relatively high N-S fertilizer is applied at relatively high rates of about 100 to 150 pounds per acre to ensure that the fertilizer nutrients are always available to the rice plants at several stages of their growing period.
