- Association Flag leaf C, N and P contents correlated positively with SPAD, Pn and dry matter accumulation.
- Association Flag leaf ecological stoichiometry correlated negatively with SPAD, Pn and dry matter accumulation.
- Mechanism Authors conclude deep fertilization increased flag leaf C, N and P, delayed senescence and promoted yield.
