The experiment aimed to explore the impact of organic fertilizer on the quality, digestive characteristics, and aerobic stability of whole-plant corn silage of different varieties. A two-factor experimental design was employed, using four corn varieties: Da Kang 205 (DK205), High Oil 958 (HO958), Zhong Yu 335 (ZY335), and Zhong Nong 787 (ZN787). Two treatments were applied: Organic fertilizer application and no organic fertilizer application. The whole plants were harvested at the wax ripening stage and subjected to whole-plant ensiling. After a 200-day fermentation period, relevant indicators were analyzed. The results showed that the interaction effect of variety and organic fertilizer had an impact on the content of lactic acid, acetic acid, propionic acid, butyric acid and ammonia nitrogen/total nitrogen ratio ( P<0.05). The Interaction effect of variety and organic fertilizer had an impact on the content of dry matter, crude protein, starch, and acid detergent fiber ( P<0.05). The organic fertilizer group exhibited higher in vitro dry matter digestibility and aerobic stability, with ZN787 showing significantly higher in vitro neutral detergent fiber digestibility than the other three varieties ( P<0.05). The study indicates that the application of organic fertilizer has varying degrees of improvement on the quality, digestive characteristics, and aerobic stability of whole-plant corn silage for different varieties. ZN787 is suitable for promoting whole-plant corn silage cultivation in the Inner Mongolia region, and the application of organic fertilizer can further enhance the silage quality.
