The agricultural news article reports a mixed impact of weather conditions on crop yields across Europe and Russia. The south-central and eastern regions of Europe have experienced adverse effects due to heat and dryness, leading to lowered yield estimates, particularly in countries like Romania, Bulgaria, Hungary, Slovakia, Austria, Poland, Lithuania, and northeastern Germany. The east of Ukraine, the south of the Russian Federation, and Belarus have also faced negative impacts due to dryness, affecting sunflower and corn yields. In contrast, Western Europe has enjoyed favorable weather conditions, resulting in increased yield forecasts. The European Commission has revised yield forecasts downward based on the initial estimates, but the full impact of the bad weather on the harvest remains uncertain.
