Other claims from this paper (11)
- Observation N accumulation was greatest (79 kg N ha-1) in 48-d S. cannabina in the first experiment.
- Intervention effect N accumulation in cowpea was apparently depressed by waterlogging.
- Intervention effect Rice grain yield response to green manure N was unaffected by whether the green manure was grown in situ or transported from a nearby field.
- Observation Mean N accumulation in flooded S. rostrata was 90 kg ha-1 in 48 d.
- Observation Mean N accumulation in flooded S. rostrata was 164 kg ha-1 in 60 d.
- Observation N accumulation in nonflooded S. rostrata was 128 kg ha-1 in 48 d.
- Observation N accumulation in nonflooded S. rostrata was 198 kg ha-1 in 60 d.
- Observation N accumulation in a Nepalese S. cannabina cultivar averaged 84% of that in S. rostrata.
- Association Rice grain yield response was a function of green manure N regardless of species or age.
- Observation S. rostrata tolerates waterlogging.
- Observation S. cannabina tolerates waterlogging.
