Abstract: In Alar City, Xinjiang Province, six different sweet sorghum (Sorghum bicolor ‘Dochna') varieties were mowed at different time nodes to determine the yield and nutrient composition of sweet sorghum, which provided theoretical support for determining the appropriate cultivar and mowing period. The results showed that, considering both yield and nutritional quality, the suitable mowing time for 6 sweet sorghum varieties was July 27. During this period, the yield of the six sweet sorghum varieties from high to low was Dalishi, Qingzhudashi, FS3501, F10, F430 and F29; the crude protein content from high to low was Dalishi, F10, F430, FS3501, F29 and Qingzhudashi; the starch content from high to low was F29, FS3501, Dalishi, F10, F430 and Qingzhudashi; the acid detergent fiber content from high to low was FS3501, F29, F10, Dalishi, F430 and Qingzhudashi; the hemicellulose content from high to low was FS3501, Dalishi, F29, Qingzhudashi, F430 and F10. By comprehensive comparison, among the six varieties, the yield and main nutrients of Dalishi and Qingzhudashi are excellent, which are suitable for planting in Alar City.
