• Enhancing the yield, quality, and potassium use efficiency of direct-seeded hybrid indica rice through wheat-straw returning combined with potassium fertilizer application (2026) · Frontiers in Plant Science · 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) · Food and Energy Security · cited 23× · 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.

• Effect of moisture regimes and crop diversification on system productivity and soil health under North Bihar conditions (2026) · Plant Science Today · doi

  The conventional rice-wheat system is associated with yield reduction and soil degradation. There is a need to diversify the conventional rice-wheat system with legumes and vegetables.

• Optimizing Fertilizer Use and Planting Density for Lowland Rice Production in Agrivoltaic Systems (2026) · International Journal of Plant Production · doi

  There is a lack of information on suitable cereal cropping practices for the AVS. The study aims to address this gap by investigating the effects of fertilizer rate and planting density on lowland rice in the AVS.
