Influence of Nitrogen Application Rate on Stem Lodging Resistance Rice under Dry Cultivation

Agronomy, 2023
High grain yields of rice (Oryza sativa) under dry cultivation are primarily obtained through high levels of nitrogen (N) input. However, excessive inputs of N increase the risk of lodging. This study aimed to clarify the effect of N application rates on
