Nitrogen threshold under straw returning: optimizing nitrogen application to synergize the yield and nutritional stoichiometry of maize
In conclusion, SP demonstrated greater potential for N fertilizer savings while achieving high grain yield and superior nutritional quality. The optimal N application rates were 113.82-129.53 kg ha<sup>-1</sup> for SP and 129.90-135.81 kg ha<sup>-1</sup> for SM, ensuring the coordinated improvement of yield, nutritional quality, and PFPN.
