The intercropping of maize and soybean leads to maximisation returns in comparison to mono cropping of maize or soybean. Which one of the following describes the enterprise relationship leading to higher returns of maize and soyabean?

Maize is mostly intercropped with legumes as it provides shade to legume species as they are smaller in size in comparison to maize plants. Thus intercropping of maize and soybean are complementary relations, as both complement each other.
