^aData was combined over years (2014 and 2016). PDCB, Planting date of common bean with maize in a mixture; SA, spatial arrangements of the component crops PLERM = partial land equivalent ratio of maize; PLERCB = partial land equivalent ratio of common bean; LER = land equivalent ratio; LEC = land equivalent coefficient; MAI = monetary advantage index.
