In order to screen the suitable mowing period with high forage yield, good quality and good silage fermentation quality of triticale in Northern Henan. Triticale varieties ʻYounengʼ and ʻLeishenʼ were used as experimental materials, and four mowing periods were set up to determine the dry matter yield, nutritional quality and silage fermentation quality. The results showed that from the heading stage to the milk stage, the dry matter yield of triticale gradually increased, with Youneng and Leishen reaching the highest of 15.64 and 16.67 t/ha, respectively. The whole plant moisture content, crude protein and crude ash contents all decreased with the delay of mowing period, the neutral detergent fiber and acid detergent fiber contents increased first and then decreased, and the principal component analysis of nutritional indicators indicated that the nutritional quality score peaked at the heading stage. The pH of silage was 4.05-4.50, the lactic acid content was 2.11%-4.00%, with no detection of butyric acid. Youneng and Leishen had better fermentation quality when mowed from flowering to filling stage, from heading to filling stage, respectively. In summary, Youneng and Leishen are suitable for mowing at the flowering and heading stages, respectively. At these stages, both varieties achieve high dry matter yields along with excellent nutritional and silage fermentation quality.
