Other claims from this paper (16)
- Intervention effect Cassava-cowpea intercropping gave approximately 25 percent greater land use efficiency than sole cropping.
- Intervention effect Intercropping produced significantly greater early leaf area and dry matter production than sole cassava.
- Intervention effect At harvest, total leaf area and dry matter were similar between intercropped and sole cropped systems.
- Association Yield reductions were associated with fewer cassava storage roots per plant.
- Association Yield reductions were associated with lower LAIs 50 to 100 days after planting.
- Intervention effect Intercropping with cowpea or peanut reduced cassava dry matter production by 200 to 600 g m('-2) in both years.
- Mechanism Peanut intercropping further reduced cassava yield in 1982, apparently through limited sink size.
- Intervention effect Cassava leaf nutrient concentrations declined while cowpea and peanut grew fastest.
- Intervention effect Cowpea seed yield and dry matter production fell by 26 to 40 percent under cassava intercropping.
- Intervention effect Peanut seed yield and dry matter production fell by 26 to 40 percent under cassava intercropping.
- Intervention effect Cowpea and peanut leaf area indices were reduced 10 to 30 percent under intercropping.
- Intervention effect Raising P application from zero to 44 kg ha('-1) increased cowpea seed yield in both years.
- Intervention effect The same P increase raised cassava yield in 1981.
- Intervention effect P rates above 44 kg ha('-1) gave no further cassava or cowpea yield increase.
- Association Cowpea leaf area and dry matter production responded more to P than cassava.
- Association Cowpea nutrient uptake responded more to P than cassava.
