The study looked at how well a new feed barley variety called Huadamai No.4 can handle being planted late in the season. They tested it with three different planting dates and found that late planting affected how long it took to grow, its appearance, how much it yielded, and its quality. The results suggest that Huadamai No.4 can still do well even when planted late, but there are some differences in how it grows and what it produces.
