• Soil Fertility Dominates the Optimal Allocation of Basal and Tillering Nitrogen in Rice Production (2026) · doi

  Excessive basal and tillering nitrogen (BTN) application in rice production causes substantial N losses and environmental costs, yet practical soil fertility thresholds to guide safe BTN reduction (RBTN) have not been established.

• Effects of a one‐time application of controlled‐release nitrogen fertilizer on quality and yield of rice (2022) · doi

  Abstract Limited information is available on the influence of a one‐time application of controlled‐release nitrogen fertilizer (CRNF) in improving both yield and quality of rice.

• A seven‐year study on the effects of four tillage modes on soil physicochemical properties, microbial biomass, enzymatic activities, and grain yield in a rice–ratoon rice cropping system (2023) · doi

  However, there is no more information on the relative impact of soil tillage practices on soil physical and chemical properties, microbial biomass, and enzymatic activity, and grain yield in a rice–ratoon rice cropping system remains to be tested.
