The study looked at how planting maize with peanuts affects maize growth and yield. They found that intercropping maize with peanuts can increase maize yield by up to 60% compared to growing maize alone. Using more nitrogen fertilizer can further boost maize growth and yield. Intercropping maize with peanuts can help distribute more nutrients to the grain, leading to a higher harvest. To get the best results, it's important to manage fertilizer and water carefully during the later stages of growth.
