This study aimed to explore the effects of organic fertilizers on the production performance and nutritional quality of cultivated grasslands in karst areas. Two types of monocultured cultivated grasslands (i.e., <i>Medicago sativa</i> and <i>Dactylis glomerata</i>) were employed as the research objects, and a randomized block design was adopted to investigate the effects of five fertilization gradients on the forage height, coverage, yield, and nutritional quality of the cultivated grasslands. According to the results, the plant height, coverage, and yield of <i>M. sativa</i> first presented an increasing Frontiers in plant science1228621https://www.ebi.ac.uk/biostudies/studies/S-EPMC10484102biostudies-literatureEffects of fertilization gradient on the production performance and nutritional quality of cultivated grasslands in karst areas.PMC10484102Jin BZhang YNiu ZTian SMa YShuai HWang YWei JZhao XfalseEffects of fertilization gradient on the production performance and nutritional quality of cultivated grasslands in karst areas.Optimal fertilization is an important measure for managing cultivated grasslands, and a necessary means for maintaining the nutrient balance, yield, and quality of grassland ecosystems.
