* CNanochitin: nanochitin application rate (mg·kg−1), DMA-VO-M: the dry matter accumulation in vegetative organs at maturity, DMT: the dry matter translocation, DMTP: the percentage of dry matter translocation from pre-anthesis vegetative organs to grains, NA-VO-M: the N accumulation in the vegetative organs at maturity, NT: the N translocation, and NTP: the percentage of N translocated from pre-anthesis vegetative organs to grains. ** Different letters of a, b, c, and d after the same column of data show significant differences among different treatments (p ≤ 0.05).
