“…Genetics and cultivation conditions, but not climate, are the main determinants of forage nutritional quality (Sohail et al, 2021). Legumes usually have higher CP contents and lower ADF and NDF contents than those of cereals (Qu et al, 2022). In our study, CP content, DMD, and RFV values of mixed crops were higher than monocultures, and no significant differences were observed between the two experimental sites.…”

To establish artificial grassland annually, oats, a traditional forage species, are normally cultivated in Qinghai–Tibetan alpine pastoral areas in spring and harvested the same year. Selection a suitable autumn‐sown forage species and succeeding crop, thus harvest of two crops per year, would increase forage yield and quality. We used the triticale variety Gannong No. 2 as an autumn‐sown crop and evaluated the performance of different succeeding crops: B1 (50% triticale and 50% common vetch), B2 (40% rye and 60% common vetch), B3 (50% oats and 50% common vetch), B4 (triticale), B5 (rye), and B6 (oats). We analysed crop productivity and nutrition at two sites in China in 2019 and 2020: Hezuo, and Lhasa. The highest hay yield (15.03 t ha−1) and crude protein content (12.22%) of autumn‐sown triticale as well as the highest average hay yield (6.05 t ha−1) and comprehensive evaluation value (0.80) of the six succeeding crops were obtained at the Lhasa site. At both sites, the succeeding crop with the highest average hay yield (6.30 t ha−1), crude protein content (13.08%), and comprehensive evaluation value (1.00) was B1. In regard to the interaction of environment and succeeding crop, the highest hay yield (8.07 t ha−1) and comprehensive evaluation value (0.95) were obtained with B1 at the Hezuo site. Forage yield and nutrition can be significantly elevated by using autumn‐sown triticale double‐cropped with B1. The results first examine double cropping in alpine pastoral areas, provide a theoretical basis for establishing a double‐cropping cultivation system in this region.

“…The study found that the common vetch monocrop had the highest CP concentration at 14.88%. Another study found that CP yields were greatest with a 3:1 ratio of oats to common vetch, increasing 21.3 and 6.1% over oats alone and wild peas alone, respectively (Qu et al, 2022). However, in this semi-arid region under summersowing conditions, the highest CP yield (696 kg ha −1 ) was in the oat-common vetch intercrop with an 80:20 seeding ratio.…”

Intercropping of annual favorable legumes with grains to produce forage is utilized extensively worldwide to improve resource use efficiency. To identify the best intercropping system for a semi-arid region of China, intercrops of oat (Avena sativa L.) and common vetch (Vicia sativa L.) at five planting proportions and oat and common vetch monocrops were produced over the 2011 and 2012 growing seasons in Xifeng, northwest China. Several indices were used to evaluate yields, competitive interrelationships between the two crops, and economic returns. The oat mono-crop had the highest dry matter yield (6.51 t ha−1), while the oat–common vetch intercrop, with an 80: 20 planting ratio, produced the highest crude protein production (696 kg ha−1). The land equivalent ratio (1.167), relative crowding coefficient (2.445), and actual yield loss (0.750) were more favorable for the oat–common vetch intercrop at a seeding ratio of 20: 80. The oat–common vetch intercrop at a seeding ratio of 20: 80 showed the highest values for monetary advantage index (35.51). Overall, the autumn-sown 20: 80 oat–common vetch intercrop was more productive from resource utilization and economic perspectives.
