|---|---|---|---|
| NGR234 | NGRΩrhcN | NGRΔnopP | |
| Flemingia congesta | 30.3 ± 3.6 (18) | 7.8 ± 1.1 (19) | 35 ± 3.1 (20) |
| Pachyrhizus tuberosus | 0.9 ± 0.2 (20) | 31 ± 2.2 (22) | 0 (22) |
| Vigna unguiculata | 36.6 ± 2.5 (16) | 39.8 ± 3 (16) | 49.9 ± 4.1 (15) |
a
Plant tests were performed in Magenta jars. Nodules of all plants fixed nitrogen (Fix+). P. tuberosus was harvested 56 days postinoculation, whereas F. congesta and V. unguiculata were grown for only 42 days.
b
Mean ± standard error of the mean. The numbers in parentheses are numbers of plants.
