Sub-plots received no nitrogen fertilization in the four fields (FC, L, C, Corg) during the two years of the study. Mature plants at harvest were counted and then expressed as mean percentages (%) of initially sown seeds. Letters a/b below numbers refer to significance classes at p < 0.05 after two-by-two comparisons between A. lipoferum CRT1-inoculated and mock-inoculated conditions (n = 5). Non-parametric Wilcoxon tests were run using blocs as a random variable.
