Other claims from this paper (10)
- Intervention effect Lime and biochar, separately or combined, improved soil chemical properties.
- Intervention effect Lime and biochar improved growth, nodulation and yield of cowpea compared with the control.
- Intervention effect Lime and biochar alone and combined reduced exchangeable acidity (Al + H) relative to the control.
- Intervention effect Cowpea yield increased with lime rate up to a point.
- Intervention effect At higher lime levels combined with biochar, cowpea yield was considerably reduced, which the authors attribute to unfavorable soil pH.
- Intervention effect The highest cowpea yield was achieved at a lime rate of 2.5 t ha −1.
- Association Pod weight was significantly correlated with pH in both years (R = −0.615 and −0.444 at P < 0.05).
- Intervention effect Lime 10 t ha −1 with biochar 10 t ha −1 reduced cowpea grain yield by 853% in 2020 and 845% in 2021 relative to 2.5 t ha −1 lime with 5 t ha −1 biochar.
- Intervention effect No significant difference in cowpea yield among 2.5 t ha −1 lime combined with 5, 7.5 or 10 t ha −1 biochar.
- Recommendation 2.5 t ha −1 lime with 5 t ha −1 biochar is recommended for cowpea production.
