- Intervention effect Intercropping cassava with rice increased cassava fresh tuber weight by 5 to 48% compared with the monocropping system.
- Intervention effect Hedgerow intercropping gave lower maize yields than a crop rotation with legume cover crops.
- Intervention effect Hedgerow intercropping gave lower rice yields than a crop rotation with legume cover crops.
- Intervention effect Hedgerow intercropping gave lower cowpea yields than a crop rotation with legume cover crops.
- Observation Maize grain yields in the 80–20 rice/maize mixture were about 0.4 Mg ha−1 in the rice — groundnut rotation.
- Intervention effect Maize grain yields were about half as much when maize was intercropped with cassava or hedgerows than in the rice — groundnut rotation.
- Intervention effect Rice yields intercropped with cassava or hedgerows were about 1 Mg ha−1 lower in years 2 and 3 than in rotation with groundnut.
- Observation Rice yield in the first cropping season was only about 1 Mg ha−1.
- Association Rice yields in the rice — legume rotation increased to around 2 and around 3 Mg ha−1 in the second and third year.
- Association The rice yield increase in the rice — legume rotation occurred despite a decline in soil organic matter content.
- Intervention effect Cassava-based systems removed much more C than the other systems (7 Mg ha−1 yr-1).
- Association Cassava-based systems returned less C to the soil (about 0.5 to 2 Mg ha−1).
- Observation In hedgerow intercropping about 2.5 Mg C ha−1 yr−1 was returned to the plot as biomass pruning and crop residues.
- Observation In hedgerow intercropping about 1.5 Mg C ha−1 yr−1 was removed from the plot as yield.
- Observation In the cover crop rotation about 2.6 Mg ha−1 yr−1 of C was returned to the plot as crop residues and legume biomass.
- Observation In the cover crop rotation about 1.1 Mg ha−1 yr−1 of C was removed from the plot.
- Association Hedgerow intercropping systems gave an N surplus of about 15 to 50 kg ha−1 yr−1 returned to the soil.
- Association The N balance of cover crop rotation systems was about 10 to 20 kg ha−1 yr−1.
- Association Cassava-based systems showed a negative N budget of about 60 kg ha−1 yr−1.
