Straw Returning Combined with Application of Sulfur-Coated Urea Improved Rice Yield and Nitrogen Use Efficiency Through Enhancing Carbon and Nitrogen Metabolism
Published 2025-07-01Get full textStraw returning inhibits tillering at the early stage of rice growth and thus affects grain yield. Sulfur-coated urea (SCU) has been expected to increase nitrogen use efficiency (NUE) and yield, save labor input, and reduce environmental pollution in crop production. Nevertheless, the sulfur coating...
