Effects of Sulfur, Phosphorus, and Nitrogen Application on the Growth and Yield of Sweet Potatoes Grown on Fredensborg Clay Loam

Abstract

The effect of sulfur, nitrogen, and phosphorus applications on the growth and yield of sweet potatoes grown on Fredensborg clay loam was evaluated. Although there was no reduction in soil pH as a result of sulfur application, yield increased with increased rates of sulfur. Yields increased significantly with nitrogen applications. Phosphorus application did not significantly affect the yield.
