MARS本月預(yù)計歐盟28國玉米單產(chǎn)為7.93噸/公頃，低于7月份預(yù)測的8.08噸/公頃，但是仍然高于過去五年均值7.62噸/公頃。
在歐洲西部和中北部的絕大部分地區(qū)，玉米單產(chǎn)預(yù)測值明顯低于五年平均水平。相反，在歐洲中南部和東南部地區(qū)，特別是保加利亞、匈牙利和羅馬尼亞，玉米單產(chǎn)預(yù)測值遠遠高于平均水平。
歐盟西部和中北部玉米單產(chǎn)潛力下降的原因在于，自6月份或者更早以來，出現(xiàn)了熱浪天氣，當時部分玉米作物進入揚花期，而且降雨低于低于平均水平。出于同一原因，本月MARS還調(diào)低了甘蔗、土豆以及青貯玉米的單產(chǎn)預(yù)測值，均低于五年均值。
