The nitrogen (N) applications had highly significant ( p ≤ 0.01) one-way effects on the main stem height, first branch length, shoot dry mass, and LAI at the flowering–pegging, pod-setting, and pod-filling stages, and had a one-way effect ( p ≤ 0.05) on the number of branches at the needle stage of flowering–pegging.
