• Effects of nitrogen application frequency under integrated water and fertiliser management on soil physicochemical properties, dry matter accumulation, photosynthetic characteristics and yield (2026) · doi

  However, the specific mechanisms by which the frequency of split nitrogen fertilizer applications influences cotton yield and NRE under water-fertilizer integration conditions remain poorly understood.

• Yield and nitrogen uptake of sole and intercropped maize and peanut in response to N fertilizer input (2019) · doi

  Cereal/legume intercropping is a potential pathway to lower fertilizer inputs, but there is insufficient knowledge on the nitrogen (N) response in species mixtures.
