This study looked at whether different fertilization methods affect the yield and quality of edible sorghum. We found that organic fertilizers (like straw, chicken manure, pig manure) and chemical fertilizers were more effective than chemical fertilizers alone. This significantly increased sorghum yields and made the soil more nutrient-rich. Some combinations yielded 10% to 110% more than before. Soil quality also improved. Increasing the amount of nitrogen fertilizer was very helpful for sorghum growth. Sorghum grew faster and had higher fresh and dry weights. It also had higher nutrients such as protein and fat. Using nitrogen fertilizers (like lime ammonium nitrate and urea) with water irrigation also made the ears heavier and had more grains. If organic fertilizers were used in combination with chemical fertilizers, such as straw plus NPK compound fertilizer, not only did the yield increase, but the sorghum also had better nutrients such as protein and fat. This method also helped improve quality. When using less fertilizer, some ecological planting methods are also effective. For example, the method of bio-fertilizer and intercropping can also make sorghum grow well, and improve both yield and feed quality.
