Other claims from this paper (7)
- Observation Sesbania incorporation contributed 393 kg N ha-1 to the soils before whole-crop barley cultivation.
- Observation The N fertilizer equivalence of sesbania without N fertilizer was 42.6% (63.9 kgN ha-1) compared with N100 in fallow soils.
- Observation Yield response to nitrogen rates in fallow soil was linear.
- Observation Yield response to nitrogen rates in sesbania-amended soil was quadratic.
- Intervention effect Whole-crop barley yield in sesbania-amended soil increased with N rates up to SN75 (115 kgN), reaching 10.3 Mg ha-1.
- Intervention effect Apparent N recovery of whole-crop barley decreased with sesbania plus increasing N fertilizer rates.
- Recommendation The optimum N rate after sesbania incorporation was N50.
