The study looked at how using different amounts of fertilizer and planting maize at different densities affects its growth and yield. They found that using a high level of fertilizer led to bigger maize plants and more yield. Planting maize at a density of 60,000 plants per hectare with a specific fertilizer mix was best for growing maize. Increasing planting density made some parts of the maize plant smaller, but also increased plant height. Overall, the best combination of fertilizer and planting density resulted in the highest yield for maize.
