e0“Optimized N application increased sclerenchymal and parenchymal tissue areas of the vascular bundle at the culm wall of the base second internode”
t0“japonica rice”
e1“In RC, optimized N application decreased the plant height, panicle neck node height, centre of gravity height, bending stress, and lodging index by 4.0–4.8%, 5.2–7.8%, 0.5–4.5%, 5.5–10.5%, and 1.8–19.5% compared with those in the conventional N application practice”
