style="line-height:150%"><span new="" roman="" style="font-family:" times="">An experiment using a split-plot factorial design within a completely randomized block design with three replications was conducted during the 2022-2023 growing season to examine the effects of various agricultural systems on the quantitative and qualitative characteristics of sorghum cultivars. The experimental treatments included four agricultural systems (high-input (conventional), medium-input, low-input, and ecological) in the main plots, along with four forage sorghum cultivars (Mansour, Speedfeed, Pegah, and Pajial) and two levels of mycorrhiza (inoculated and non-inoculated) in the subplots. The results showed that in the high-input agricultural system with inoculation, the Pajial cultivar exhibited the highest leaf area index (9). The highest plant height and stem diameter in the Speedfeed and Pajial cultivars were also achieved in the high-input agricultural system with mycorrhiza, while the medium-input agricultural system performed better for the Pegah and Mansour cultivars. The results further indicated that the highest fresh forage weight was obtained from the high-input agricultural system without inoculation, with fresh forage yields for the Mansour and Speedfeed cultivars increased by 44% and 47% and for the Pegah and Pajial cultivars by 45% and 38% compared to the low-input agricultural system. The highest yield (9475 kg/ha) corresponded to the Speedfeed cultivar in the high-input agricultural system with mycorrhiza inoculation. Additionally, the high-input agricultural system led to a reduction in forage fiber, with the highest percentage of crude fiber observed in the low-input agricultural system, whereas the medium and high-input systems had the least fiber content. Overall, it was determined that the ecological agricultural system, combined with mycorrhiza, not only improves the quality of sorghum forage but can also achieve a satisfactory yield. Additionally, it plays a significant role in the sustainable production of sorghum, particularly in the Speedfeed cultivar.</span></span></span></b></span></span></span></span></div> پروتئین, فیبر, شاخص سطح برگ و عملکرد علوفه.
