UGA said in a report the sown area included 1.98 million hectares of corn, 2.4 million hectares of sunflower, 854,000 hectares of barley, 336,000 hectares of soy beans and 186,000 hectares of spring wheat.
The union has said Ukraine planned to sow 11.45 million hectares of spring grains this year, 3.5 to 4 million hectares less than in 2021 due to the Russian invasion, the "occupation of territories" and landmines.
It also said the area under spring wheat could total 190,000 hectares, 900,000 hectares of spring barley and 3.9 million hectares of corn.
Ukraine's agriculture ministry gave no 2022 grain crop outlook. It has said the sowing area could fall 20% this year due to fighting with Russian troops in many regions.
