These were all significantly greater than the okra monoculture which yielded 1.1 kg plant 1. Cowpea had a reduction in per plant production in both 2011and 2012 in intercropping combinations containing watermelon when compared to cowpea monoculture, suggesting it was also subject to over-competition from watermelon. A similar trend was found in pepper production, with the pepper monoculture producing significantly greater amounts per plant. In 2011 production was 0.04 kg plant 1 in pepper monoculture versus 0.01 kg plant 1 inWall treatment combination. In 2012, pepper monoculture production was 0.16 kg plant 1 versus 0.07 in the Wall treatment. Increased per plant production in 2012 compared to 2011 for pepper also suggests that the changes in planting dates in 2012 allowed proper pepper establishment and reduced competition fromwatermelon. Peanut was only harvested in 2012. Peanut production was improved in the Wpwo and Wpwoc intercropping combinations, 0.10 and 0.11 kg plant 1, respectively, and was lowest in the Wall and peanut–watermelon strip intercropping treatment (Spw) at 0.06 and 0.07 kg plant 1, respectively.
