  1. The T1, T2, and T3 represent “40:160” (maize narrow and wide row spacing of 40 and 160 cm, where two rows of soybean with a 40-cm row were planted in the wide rows), “80:120” (maize narrow and wide row spacing were 80 and 120 cm, the soybean planting was the same as T1 treatment), “100:100” (one row of maize and one row of soybean with a 100-cm row) respectively. Values followed by different letters within the same line show a significant difference between different treatments (P < 0.05).
