Sorghum represents the third-largest cereal grain in the United States, with 9,473,184 metric tons yield and 2,061,873 ha area in 2020. Because sorghum is a heat- and drought-tolerant crop, its acreage is increasing under low or no irrigation conditions in semi-arid environments. This study aimed to evaluate the response of diverse winter cover crop species and their mixtures on soil C and N fractions and subsequent sorghum yield under limited irrigation in a no-till winter wheat-sorghum-fallow rotation.
