The study aimed to test the impact of using a specific fertilizer on maize crops to help farmers increase their yields. By comparing the effects of this special fertilizer with traditional methods, researchers found that the maize plants treated with the new formula had fuller grains and more kernels per row, leading to a 9.40% increase in yield. This resulted in higher economic benefits, with a net gain of 3.47 yuan for every 1 yuan invested in the new fertilizer. The study suggests that using this formula fertilizer can improve maize production significantly compared to conventional methods.
