The study looked at how different ways of giving plants nutrients affect the growth and yield of maize. They found that using the right balance of nutrients helps plants grow better and produce more. One type of maize variety, called "stay-green," did better than the traditional variety in terms of leaf area and nitrogen use. Not giving enough phosphorus and potassium to the plants reduced their yield. Overall, balanced nutrient management is important for getting the most out of maize crops.
