KYIV, May 20 (Reuters) - Recent severe frosts across Ukraine's northern and eastern regions could reduce this year's grain and oilseed harvest, analyst APK-Inform said on Monday.

The consultancy quoted agricultural scientists as saying that the air temperature early in May decreased to minus 2 Celsius degrees (28.4 Fahrenheit) and to minus 9 Celsius (15.8 Fahrenheit) in some areas.

Frosts have damaged crops of wheat, barley, rapeseed and peas, they said, adding that 20% to 30% of the yield could be lost.

The ministry, which forecast the 2024 combined oilseed and grain harvest at 74 million metric tons, does not comment the situation.
