Rice yield and quality decline due to excessive fertiliser use is problematic in China. To increase rice grain filling improve quality, a nitrogen reduction density study 2023 2024 was imposed on long-term experimental field. The four treatments adopted for the were normal (CK), increased (NN+ID), reduced panicle (RPN+ID), basal (RBN+ID). RPN+ID RBN+ID, respectively, produced 3.0% 5.1% higher than CK both years. mean rate (Va) of superior grains RBN+ID by 12.5%, while inferior treatment 4.2% with respect CK. caused 0.4%, 9.6%, 13.3% brown rate, chalkiness degree, triggered 7.2%, 11.0% respectively. stimulated 3.1% increases flavour straight-chain amylose values, Whereas 20% 32% improved appearance rice, at stage promoted steaming quality. Therefore, an appropriate simultaneously increasing has significant impact pollution reduction, theoretical basis improvement Northeast
