Abstract：The experiment aimed to screen high-yielding and high-quality silage corn varieties suitable for planting in the Yellow River irrigation area of Ningxia.A total of seven silage corn varieties were selected for field experiments to compare their agronomic traits,yield,nutritional quality,and comprehensively evaluate the feeding value of each variety.The results showed that Yinyu 439 and Yinyu 6118 had the highest fresh ear weights,measuring 453.00 g and 464.00 g,respectively.Yinyu 439 and Tianci 19 had the highest number of green leaves,with 13.50 and 13.40,respectively.Yinyu 238 exhibited the tallest plant height,reaching 333.00 cm,while Yinyu 439 had the largest stem diameter of 24.30 cm.Yinyu 439 also showed the highest leaf fresh weight at 165.00 g.Yinyu 6118 achieved the highest fresh weight yield of 76.65 t/hm2,and Yinyu 439 had the highest dry weight yield of 24.00 t/hm2.Yinyu 6118 recorded the lowest neutral detergent fiber(NDF)and acid detergent fiber(ADF)contents,at 39.60％and 20.10％,respectively,and the highest crude protein(CP)content of 10.80％.Yinyu 439 had the highest starch(ST)content of 32.40％.Grey relational analysis indicated that Yinyu 439,Xianyu 1321,Yinyu 6118,and Xianyu 1225 demonstrated superior overall performance.The study indicates that Yinyu 439,Xianyu 1321,Yinyu 6118,and Xianyu 1225 are suitable for promotion and application as main silage corn varieties in the Yellow River irrigation area of Ningxia.
