Other claims from this paper (10)
- Intervention effect Chickpea yield was greatly reduced after waterlogging.
- Observation Field-scale chickpea nitrogen derived from fixation ranged from 51 to 93%.
- Association Field-scale fixation percentage was related to soil-derived nitrogen in chickpea.
- Association Total chickpea grain nitrogen did not rise as fixation increased at field scale.
- Observation At micro scale, fixation percentage ranged from zero to 72%.
- Association Micro-scale fixation percentage related primarily to yield and total plant nitrogen.
- Association Available soil nitrogen and other soil properties were not significant predictors of micro-scale fixation percentage.
- Association Micro-scale total grain nitrogen increased solely through nitrogen fixation.
- Observation Fixation percentage had nearly pure nugget variance across scales.
- Observation Total nitrogen from fixation showed relatively high spatial correlation.
