| Abstract: |
| In this study, we compared four oats varieties (Ogle, Monida, Junma and Shahuangmai), which were cultivated in the Eastern of Qinghai region, about their productivity, biomass distribution, and nutritional quality. As the results shown, among the four oats varieties, the height of Shahuangmai (Shm) peaked at the heading stage (136.3 cm), and the fresh grass reached the maxinum yield at filling stage (21 716.73 kg·hm-2). At the same time, the shoot/leaf ratio of Shm was lower than that of other varieties, which indicated a higher leaf proportion in aboveground biomass. The range of the crude protein content of these four oats varieties were among 5.31%~8.54% and the neutral detergent fiber and acid detergent fiber content were among 54%~65% and 30%~40%, respectively. Overall, the nutritional quality of these four oats were little lower. More work need to be done to improve the introduced oat varieties from the agricultural practice in the local place. |
