Figure 5

Structural equation model relating tillage and residue treatments to yield of spring maize in 2014 (a) and 2015 (b). T and R in the boxes represent tillage and residue treatments, respectively. Boxes represent variables past the Pearson test and Regression analysis. Arrows show the direct effects of one variable on the others. Values next to the arrows are standardized path coefficients. Solid and dashed lines indicate significance (P < 0.05) and non-significance (P > 0.05).
