Comparison of Agronomic Traits Among Different Oat Varieties There were highly significant differences in plant height among various oat varieties at the harvest stage ( p < 0.05) ( Figure 2 a).
Comparison of Agronomic Traits Among Different Oat Varieties There were highly significant differences in plant height among various oat varieties at the harvest stage ( p < 0.05) ( Figure 2 a).
In the 0–15 cm and 15–30 cm soil layers of different oat varieties, the contents of pH, EC, total salt, Ca 2+ , Mg 2+ , and HCO 3 − showed a decreasing trend at the harvest stage compared to the seedling stage, while the contents of organic matter, total nitrogen, Cl − , and SO4 2− showed an increasing trend.
