• Enhancing the yield, quality, and potassium use efficiency of direct-seeded hybrid indica rice through wheat-straw returning combined with potassium fertilizer application (2026) · doi

  However, in rice–wheat rotation systems, the synergistic effects of wheat-straw returning and optimized K fertilization on yield, rice quality, and KUE of direct-seeded rice remain poorly understood.

• Energy assessment of different rice–wheat rotation systems (2021) · doi

  The rice–wheat rotation system provides a stable source of food for more than 20% of the world's population, but there have been no reports on the energy balance of different rice–wheat rotation systems.
