| description | Mixing cereal with legume crops is an efficient approach for improving forage production and ensuring the sustainable development of agriculture and livestock. However, the knowledge of the relationship between forage production and interspecific competition in the forage oat (<i>Avena sativa</i> L.) and common vetch (<i>Vicia sativa</i> L.) mixed cropping system remains unclear. A 2-year field experiment was conducted in 2020 and 2021 to investigate the effects of different mixed cropping systems (peer mixing (PM), alternate-row mixing (AM), cross mixing (CM), bar mixing (BM), sole forage oat (SO), and sole common vetch (SV)) on the dry matter production, forage quality, land equivalent ratio (LER), and competition parameters. The results showed that the system forage yield increased by 13.4–202.8% when forage oat was mixed with common vetch (<i>p</i> < 0.05). However, no significant difference was obtained between the AM and PM mixed cropping systems. Additionally, the forage oat–common vetch mixed cropping improved crude protein yield by 52.5–150.1% compared with monocultures (<i>p</i> < 0.05). The LER values were greater than the one when forage oat was mixed with common vetch, especially for the AM system (averaged 1.38). In addition, forage oat was the dominant crop and had higher aggressiveness and competitive ratios compared to common vetch, but without a significant difference in the aggressiveness and competitive ratio in mixed cropping systems. It indicated that mixing of cereal with legume crops was helpful in enhancing resource use efficiency without obvious interspecific competition. Consequently, the AM mixed cropping system is recommended for supporting the sustainable development of agriculture and livestock production in the arid region of China when considering both forage production and nutritional quality. |
