  1. Treatment codes represent narrow-strips (T1, 180 cm); medium-strips (T2, 200 cm); and wide-strips (T3, 220 cm) in maize/soybean relay intercropping system. SS is the sole cropping system of soybean. Means are averages over three replicates ± standard error of the mean. Means that do not share the same letters in a column differ significantly at p ≤ 0.05 using least significant differences, calculated separately for each year.
