Table 1 a) Number of nodules per plant b) root dry weight (g) and c) number of nodules per g of root tissue from the six genotype experiment with three soil nitrogen treatments: high nitrogen (HN, paddock soil + N), medium nitrogen (MN, paddock soil no N) and low nitrogen (LN, sand:soil 2:1). Measurements taken 6 weeks post-inoculation with rhizobia. Standard error of the differences among means (SED) and least significant difference (LSD) values included
