e1“Intercropping with cowpea resulted in 0.8, 0.6, and 0.3 g kg −1 lower P concentration [P], and 5.2,4.9, and 2.9 kg 1 lower [N] in cassava stems, leaves, and storage roots, than resulted from sole‐cropped cassava 50 days after planting”

Other claims from this paper (8)
- Intervention effect Intercropping with cowpea lowered cassava N concentration in stems, leaves and storage roots compared with sole-cropped cassava 50 days after planting.
- Intervention effect Intercropping had no influence on N, P or K of cassava at later harvest dates.
- Intervention effect Similar results occurred when cassava was intercropped with peanut.
- Association Peanut was a less vigorous competitor with cassava for P than cowpea was.
- Intervention effect Cassava-cowpea and cassava-peanut intercropping removed 3.0 to 7.5 g m-2 more N than sole-cropped cassava.
- Intervention effect Cassava-cowpea and cassava-peanut intercropping removed 0.30 to 0.47 g m-2 more P than sole-cropped cassava.
- Intervention effect Cassava-cowpea and cassava-peanut intercropping removed 2.5 to 5.1 g m-2 more K than sole-cropped cassava.
- Association Intercropping systems are suggested to lead to a more rapid mining of natural soil fertility.
