TL;DR: The correlation analysis revealed that the grain yield was significantly related to ammonium assimilation enzyme activities, photosynthetic rate, and root activity, respectively, at several rice growth stages, and suggested that the N application strategy should be adjusted according to different irrigation regimes in order to obtain the highest yield and the best NUE.

TL;DR: Correlation analysis showed that the rice quality was extremely significantly positively correlated with the root morphology indexes of the brown rice and protein contents and was significantly or extremely negatively correlation with the length–width ratio, percentage of chalky kernels, chalkiness degree and amylose content.

TL;DR: In this paper, a study was conducted to evaluate grain yield performance and yield component changes of heavy panicle varieties under triangle planting geometry (TPG) where plants form a dense intra-hill, sparse inter-hill group structure.

TL;DR: In this article, the role of postanthesis carbon and nitrogen metabolism of hybrid rice in increasing yield and nitrogen utilization efficiency (NUE) was explored, and different irrigation and nitrogen fertilization regimes were established to investigate the relationship of C-N metabolism characteristics, yield, and NUE.

TL;DR: In this article, the effects of the N application rates and the N fertilizer management strategies for rapeseed and rice were examined, respectively, in relation to the photosynthetic productivity and yields of hybrid rice.
