Winter barley, once a minor crop in Poland, has seen a significant rise in cultivation area, surpassing 355,000 hectares in 2023, according to ARiMR. This increase is attributed to the shifting climate, which has reduced the risk of winterkill and allowed winter barley to thrive as a precursor to winter oilseed rape. Winter barley is favored for its early maturation and resistance to spring droughts, making it an ideal choice for farmers seeking to optimize their crop rotations.
Importance of Winter Barley as a Precursor Crop
Winter barley’s rapid harvest timing allows for early preparation of fields for subsequent crops, such as winter oilseed rape. In contrast to other winter cereals, barley is harvested significantly earlier—typically around early July—compared to other grains, which are harvested about three weeks later. This early harvest enables farmers to prepare the soil, adjust pH levels, and plant cover crops effectively, enhancing soil health and subsequent crop performance.
Assessing Winter Hardiness
Despite its benefits, winter barley is less winter-hardy compared to other cereals. However, modern varieties have shown improvements in winter resilience. The winter hardiness of winter barley varieties is rated on a scale from 1 to 9, with a difference of one point roughly translating to a 10% increase in plant survival during severe winters. Current varieties like Giewont, Impala, Yukon, and Zenek are rated up to 5.5°, demonstrating higher resistance to harsh conditions.
Recommended Varieties for 2024/2025
Here are some top winter barley varieties for the 2024/2025 season, each with specific strengths:
- Jakubus:

Winter barley continues to gain popularity due to its early harvest and suitability as a precursor for subsequent crops like winter oilseed rape. While it faces challenges with winter hardiness, advancements in breeding have led to the development of more resilient varieties. By selecting the right variety from the list of recommended cultivars for the 2024/2025 season, farmers can optimize their yields and enhance crop rotation efficiency.
