Fig. 2. Land equivalent ratios (LERs) calculated based on total yield for (a) 2011 and (b) 2012 and broken down by species (Wpw =within row intercropping of peanut– watermelon, Spw = strip intercropping with peanut–watermelon (e.g. alternating rows), Wpwo = within row intercropping of peanut–watermelon–okra, Wpwoc = within row intercropping of peanut–watermelon–okra–cowpea, Wall = within row intercropping of peanut–watermelon–okra–cowpea–pepper). Cumulative LER values >1 indicate overyielding at the plot level, while cumulative LER
