Winter Barley Harvest Begins Amid Weather Woes and Disappointing Yields
Tillage farmers are reporting that almost all winter barley crops are now fully ripe and ready for the combine. However, persistent changeable weather over the past fortnight has delayed the harvest. With a couple of dry days forecasted mid-week, combines are expected to be out in force soon. Despite the readiness, yields have been underwhelming, raising concerns about underlying issues affecting the crops.
Harvesting Conditions and Yields
Farmers have observed that the barley crops harvested so far this season have delivered disappointing yields. While a few fields have managed up to 4 tonnes per hectare (t/ha), many have fallen below 3t/ha, with an average yield around 3t/ha. Even fields that appeared promising before harvest have underperformed. This shortfall contrasts with the dramatic improvement seen in these crops during the spring, following poor planting conditions last September.
Potential Causes of Poor Yields
The unexpected decline in yields has led growers to speculate that disease factors, rather than weather alone, may be the primary cause. Given the significant improvement of crops in spring, the poor yields have been surprising, prompting a closer look at possible disease impacts. The current conditions and yield data underscore the importance of robust disease management practices in ensuring crop health and productivity.
Broader European Context
Ireland is not alone in facing these challenges. The Agricultural and Horticultural Development Board (AHDB) reports disappointing yields and quality in both France and Germany. Persistent wet weather has not only delayed harvests but also affected crop outcomes. Germany anticipates a reduction in total winter barley output by 2% to 6% compared to 2023. Meanwhile, France has begun harvesting spring barley, crucial for European malting supplies, with 15% of the crop already combined.
Global Weather Impact: La Niña Predictions
The broader impact of global weather patterns cannot be overlooked. American weather organizations have predicted a 65% likelihood of a La Niña event developing between July and September, increasing to 85% during November to January. La Niña, characterized by cooler South Pacific temperatures, leads to reduced rainfall and increased temperatures in South America, stressing crops and reducing yields. Given South America’s vital role in global soya bean and maize supply, a significant La Niña event could create a bullish market sentiment due to anticipated reductions in crop yields.
The current harvesting challenges for winter barley in Ireland, coupled with similar issues in France and Germany, highlight the complexities faced by tillage farmers this season. While weather has played a significant role, the potential impact of disease underscores the need for vigilant crop management practices. The looming threat of La Niña further emphasizes the importance of adaptive strategies in the face of global climate variability.
