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. Keywords Sorghum(Sorghum bicolor L.); Fertilization strategy; Yield; Quality; Organic-inorganic combination 1 Introduction Sorghum(Sorghum bicolor L.) is a crop with many uses and is important all over the world. It can be used as food, but is also often used to make feed, syrup and alcohol. It has strong adaptability and can grow in drought or poor soil. Therefore, sorghum is very helpful for food security and farmers' income (Kubiku et al., 2022; Akinseye et al., 2023; Sadafzadeh et al., 2023). Now that the population is increasing, people are more and more particular about the quality of food, which makes people have higher requirements for the yield and quality of sorghum. In order to meet this demand, many studies have begun to focus on how to grow sorghum in a more efficient and sustainable way (Wang et al., 2024; 2025). Now agricultural development emphasizes sustainability, that is, it is necessary to grow more food and protect the environment. Therefore, how to use fertilizer well has become a problem of particular concern to everyone. Reasonable fertilization can not only make sorghum grow more and better, but also improve the soil, make fertilizer use more efficient, and reduce damage to the environment (Ganyo et al., 2019; Bartzialis et al., 2023; Sadafzadeh et al., 2023; Wang et al., 2024; 2025). It is not clear which of the different fertilization methods, such as organic fertilizer, inorganic fertilizer, biological fertilizer, or combined with irrigation, is the most suitable and how to combine them to be the most effective. These issues need further sorting and analysis. This review mainly wants to summarize the effects of various fertilization methods on sorghum yield and quality. We focused on organic fertilizers, inorganic fertilizers, and biofertilizers, as well as their use in combination with irrigation (Ganyo et al., 2019; Kubiku et al., 2022; Akinseye et al., 2023; Bartzialis et al., 2023; Sadafzadeh et al., 2023; Wang et al., 2024; 2025). We compared the effects of these methods in different environments and planting methods, trying to find good ways to improve sorghum yield and quality at the same time. Finally, we also proposed some issues that should be focused on in the future, such as how to maintain soil nutrient balance, how to use fertilizers more efficiently, and
