  1. The SI (50 cm: 50 cm) and SII (40 cm: 160 cm) represent the different planting patterns under relay-intercropping system. The SM and SS refer to sole cropping system of maize and soybean, respectively. The LERm and LERs represent the land equivalent ratio of maize and soybean, respectively, and CRs refer to competition ratio of soybean. Means are averaged over three replicates. Means do not share the same letters in the column differ significantly at p ≤ 0.05; NS = Non-significant.
