Supporting evidence — 8 representative gaps

• A High Amount of Straw Pellets Returning Delays Maize Leaf Senescence, Improves Dry Matter Accumulation and Distribution, and Yield Increase in Northeast China (2025) · Agronomy · cited 8× · doi

  Further research could explore the effects of different straw pellet sizes and densities on maize yield. The study could be replicated in other regions to determine if the results are generalizable. Research could investigate the economic feasibility of implementing straw pellet returning on a large scale.

• Water-Saving and Yield-Increasing Strategies for Maize Under Drip Irrigation and Straw Mulching in Semi-Arid Regions (2025) · Agronomy · cited 4× · doi

  There is a need to study the effects of drip irrigation and straw mulching on maize production in semi-arid regions. Prior work has focused on optimizing water and fertilizer management, but the effects of straw mulching on maize yield and water-use efficiency are not well understood. The optimal irrigation amount and straw return method for improving maize yield and water-use efficiency are not well established.

• Optimizing Water and Nitrogen Application to Furrow-Irrigated Summer Corn Using the AquaCrop Model (2025) · Agronomy · cited 4× · doi

  The gap in current research is the lack of optimized irrigation and nitrogen management systems for furrow-irrigated summer maize. The study aims to address this gap by identifying the optimal irrigation quota and nitrogen application rate. The gap is significant because over-fertilization and over-irrigation are degrading arable land conditions and constraining crop growth.
