From: Impact of varied tillage practices and phosphorus fertilization regimes on wheat yield and grain quality parameters in a five-year corn-wheat rotation system

Figure 2

Effect of various treatments on wheat grain N concentration (A), wheat straw K concentration (B), wheat grain K concentration (C), wheat straw P concentration (D), and wheat grain P concentration (E) in a five-year corn-wheat rotation. CT, conventional tillage; MT, minimum tillage; NT, no tillage; P0, no phosphorus fertilizer use; and PR, 100% fertilizer recommendation. Different letters indicate significant differences according to the Duncan at p ≤ 0.05.
