The goal of the study was to see how different levels of nitrogen and phosphorus fertilizers affect the growth and yield of maize plants. The researchers found that phosphorus helps with plant growth and early leaf development, while nitrogen is important for overall plant health and grain size. High levels of phosphorus fertilizer led to increased yields and better grain quality. Both nitrogen and phosphorus are crucial for the growth and development of maize plants, affecting things like plant height, leaf number, and grain weight.
