Effect of MCP inoculation on total root length of maize (cv Jessy) after a culture period of (A) 28 DAS and (B) 41 DAS on a clay-loam field soil (pH 5.9) with low P availability (Soil 2) supplied with moderate soluble P fertilization (30 mg P kg−1) and N in form of Ca-nitrate (NO3−) or DMPP-stabilized ammonium (NH4+) Data represent means and SD of five replicates. A one-way ANOVA with Tukey test was performed. Different letters indicate significant differences between treatments (p < 0.05); ns = not significant.
