Shoot dry weight (SDW), symbiotic effectiveness (SE, calculated as % relative to SDW of +N controls), shoot nitrogen content (SN, given as% of SDW) and shoot nitrogen derived from the atmosphere (Ndfa, calculated as % SN relative to −N controls). Average values are given (n = 3) ± standard deviation. +N control: fertilized uninoculated; −N: non-fertilized uninoculated. Average values in the same column, followed by the same letter, are not significantly different at the 5% probability level by Tukey’s test. na, not applicable; ns, non-significant; ^∗significant at 0.05; ^∗∗∗significant at 0.001. The means and levels of siginificance for each parameter were re-calculated for CPH relative to +N and −N controls.
