The main agricultural product of Ireland is the potato, which has played a significant role in the Irish diet and economy since its introduction in the late 16th century. The crop flourished in the Irish climate and became a staple food that supported the population. However, the Great Famine in the mid-19th century, caused by potato blight, drastically affected Ireland's demographics. Today, Ireland produces a wide range of crops, but potatoes remain culturally significant, often featured in traditional Irish dishes. Other important agricultural products in Ireland include beef, dairy, and barley, but potatoes continue to symbolize Irish farming heritage.
