The researchers studied how reducing nitrogen application and changing fertilization distances can save fertilizer and increase yields in a maize/soybean intercropping system. They tested different nitrogen levels and distances between fertilizer and plants in a field experiment. Results showed that using less nitrogen and placing fertilizer closer to the plants improved dry matter accumulation, translocation, and grain production for both maize and soybean. The best results were seen with a moderate nitrogen level and a specific fertilization distance. Overall, reducing nitrogen application and optimizing fertilization distance can help transfer more nutrients to the grains, leading to better crop yields in intercropping systems.
