TABLE 4.

Symbiotic performance of 11 N₂O reducing Bradyrhizobium strains inoculated with groundnut was determined based on nodule number (NN), nodule dry weight (NDW), 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.
