The study looked at how growing maize and legumes together in the summer of 2018 affected their yield, competitiveness, and economic value. The researchers found that intercropping maize with legumes led to higher yields compared to growing them separately. The intercropping system also improved the competitive ability of the crops against weeds, resulting in better overall performance. Additionally, the economic analysis showed that the intercropping system was more profitable than growing maize and legumes alone.
