Intercropping reduces yields but boosts plant height and seed size in maize + legume systems.
Planting configurations in maize + soybean and maize + bushbean intercropping systems were studied to see how they affect crop yields. The researchers found that intercropping reduced yields compared to sole cropping. Maize had the highest plant height, cob length, and grain yield when grown alone. Intercropping increased plant height in soybean and bushbean but reduced pod and seed numbers. However, seed size increased in both legumes. The weight of 100 seeds was highest in maize + soybean and maize + bushbean intercropping systems. Overall, the highest maize equivalent yield was achieved in maize + bushbean intercropping with a single row arrangement of maize.
