Other claims from this paper (13)
- Observation The cultivars had almost identical percent nitrogen derived from atmosphere under comparable conditions.
- Observation Percent nitrogen derived from atmosphere varied from 38 to 70% in lysimeters.
- Observation Percent nitrogen derived from atmosphere reached 67% in the field.
- Observation X005 fixed 115 kg N/ha, significantly more than Maple Presto at 82 kg N/ha.
- Observation X005 had higher N yield than Maple Presto.
- Intervention effect Inoculated cultivars did not increase N yield under increasing fertilizer N rates.
- Observation Highest fertilizer use efficiency was 51% when uninoculated.
- Observation Highest fertilizer use efficiency was 44% when seed was inoculated.
- Observation Both cultivars still fixed nitrogen at up to 160 kg N/ha fertilizer.
- Intervention effect X005 fixation decreased 24% at 160 kg N/ha.
- Intervention effect Maple Presto fixation stayed constant from 0 to 40 kg/ha fertilizer.
- Intervention effect Maple Presto fixation decreased 21% at 80 or 160 kg N/ha.
- Observation Both cultivars had nitrogen fixation similar to soybeans in other countries.
