Thriving rye in south Germany, Stefan Niemeyer In shortCrop conditions across Europe remain generally favourable, with winter crops developing well overall. Spring sowing campaigns are nearing completion in many regions, but cool and wet conditions have delayed field operations and early crop development in south-eastern Europe and Türkiye.Late frost events may have affected rapeseed locally in parts of central and eastern Europe. Insufficient rainfall in April in central, eastern and northern Europe slowed down biomass accumulation. However, recent and upcoming cooler and wetter weather in central and south-eastern Europe may replenish soil moisture and improve crop development. Yield forecasts have been slightly reduced this month to account for these limiting conditions, but they still remain largely in line with or above the five-year average.This edition includes an extended analysis of the Maghreb, where continued above-average rainfall and favourable reservoir levels have supported exceptionally positive growing conditions and strong yield prospects, especially in Morocco and Algeria.Areas of concernThe main concerns relate to persistent rainfall deficits in central, eastern and northern Europe and to late frosts locally affecting rapeseed. In parts of south-eastern Europe and Türkiye, cool and wet conditions have delayed spring sowing. Persistent rainfall deficits raise concerns in central, eastern and northern EuropeRainfall deficits have persisted in several regions, leading to declining soil moisture levels. Although recent rainfall helped to improve conditions in some areas, concerns remain in areas where soil moisture deficits have accumulated since early spring.Western France: Persistent dry and warm weather progressively reduced soil moisture until abundant rainfall in May restored it, sustaining crop growth.Northern and central Italy: Above-average temperatures combined with limited precipitation depleted topsoil moisture. In northern regions, early irrigation was required locally to support the germination and early development of summer crops.South-eastern and south-western Germany, Austria, Czechia, Slovakia, Slovenia, Croatia and Hungary: Below-average precipitation since March has depleted soil moisture and raised concerns about emerging water stress. Recent rainfall brought partial relief, and more is forecast in some regions, but crop conditions still require monitoring.Eastern Poland and southern Sweden: Prolonged dry conditions have increasingly depleted soil moisture reserves. Additional rainfall will be needed as winter crops enter their reproductive stages.Western Ukraine: Persistent rainfall deficits following several months of below-average precipitation continue to worsen soil moisture conditions. Late frost events may affect rapeseed in central and eastern EuropeCold spells in late April and early May brought minimum temperatures locally below –5 °C and affected crops during sensitive development stages.Poland, Czechia and Lithuania: Frost events that occurred during rapeseed flowering reduced flower numbers and fertility. Yield expectations for rapeseed and winter crops have dropped below the five-year average in several regions, although some recovery remains possible.Hungary, eastern Slovakia and western Romania: Local frost damage was reported following frost events in April and early May, particularly affecting rapeseed.Cool and wet conditions delay spring sowing in south-eastern Europe and TürkiyeEastern Romania and Bulgaria: Cool and wet conditions have delayed sowing operations for maize and sunflowers. Delayed crop development may increase vulnerability to summer heat and water stress later in the season.Türkiye: Cool and wet spring conditions have delayed crop development, notably in central regions.Unfavourable growth in northern SpainDry conditions in northern Spain in autumn and early winter delayed the sowing of winter crops and negatively affected crop emergence. Despite favourable spring weather, winter crops continue to show suboptimal biomass accumulation, with limited recovery potential as flowering is already under way.2026 JRC MARS Bulletin surveyThe JRC invites readers to participate in its annual user survey on the MARS Bulletin.
