Intercropping maize and soybean in strip patterns can increase crop productivity and water use efficiency in irrigated areas. Wider strips of soybean between maize rows resulted in higher yields due to less shading from maize plants. Maize was found to be a stronger competitor for water compared to soybean in the intercropping systems. Overall, intercropped maize and soybean produced higher yields compared to sole cropping, showing the dominance of maize over soybean when grown together. The results suggest that maize-soybean strip intercropping is a productive and sustainable strategy to improve water use efficiency and land productivity in irrigated conditions.
