t0“Maize/Cowpea Intercrop System”
e0“In terms of LER and total seed protein yield, there was no advantage of either staggered sowings over simultaneous sowing or of the various intercrop density combinations, except between the lowest and the highest densities of either maize or cowpea”

Other claims from this paper (8)
- Intervention effect Maize yield in the maize/cowpea intercrop was reduced when maize was sown at the same time as cowpea.
- Intervention effect Maize yield in the maize/cowpea intercrop was reduced when maize was sown after cowpea.
- Intervention effect Intercrop cowpea yields were less than sole cowpea yields at all sowings.
- Intervention effect Increasing the density of either crop in the maize/cowpea mixture increased total yield.
- Intervention effect Maize reduced cowpea yields more than cowpea reduced maize yields.
- Intervention effect In terms of LER and total seed protein yield, staggered sowings had no advantage over simultaneous sowing.
- Association The LERs appeared to follow the trends in cowpea yields.
- Association Total seed protein yields appeared to follow the trends in maize yields.
