Air Charter Service has told the BBC that the first flight will land on Thursday in Stansted carrying 150 Romanian farm workers.
The firm told the BBC that the plane is the first of up to six set to operate between mid-April and the end of June.
Government department Defra said it was encouraging people across the UK “to help bring the harvest in”.
British farmers recently warned that crops could be left to rot in the field because of a shortage of seasonal workers from Eastern Europe. Travel restrictions due to the coronavirus lockdown have meant most workers have stayed at home.
Several UK growers have launched a recruitment drive, calling for local workers to join the harvest to prevent millions of tonnes of fruit and vegetables going to waste. However concerns remain that they won’t be able to fulfil the demand on farms.
