Agriculture in Scotland In June 2013, of crops grown in Scotland (excluding grass), cereals accounted for 78 per cent of the land area, with nearly three-quarters of that being barley (340,000 hectares). Wheat was also significant (87,000 hectares), along with oilseed rape (34,000 hectares), oats (32,000 hectares) and potatoes (29,000 hectares). Amongst fruit and vegetables, a total of 911 hectares of strawberries were grown, mainly under cover, which was the largest source of income amongst horticulture crops.[49] The major areas of cereal production were Grampian, Tayside, Borders, Lothian and Fife.[51]
