The study looked at how using a specific type of fertilizer can increase the yield and profit of summer maize crops. By following expert recommendations for fertilization, the grain yield went up by 5.28% and profit by 6.71%. This method also helped the plants absorb and use nutrients better, keeping the soil healthy. The fertilizer used was efficient, with every kilogram applied resulting in 38.25 kilograms of grain. This approach is worth using for growing super-high-yield summer maize.
