Intercropping maize and soybean can increase crop production by using sunlight more efficiently. In the study, two intercropping patterns were compared to growing the crops separately. The results showed that intercropping had higher maize biomass after 79 days and soybean biomass was significantly different between intercropping and monoculture. The radiation use efficiency of intercropping was higher than monoculture for soybean but slightly lower for maize. Although grain yields were higher in monoculture, total yields and incomes were significantly higher in intercropping systems. This suggests that intercropping can help farmers increase their income by maximizing the use of solar radiation.
