Which crops are especially important to South Australia’s agricultural economy?

South Australia’s agricultural economy is supported by a diverse range of crops, with several playing a vital role in both domestic and export markets:

• Wheat: Long a mainstay of the state's farming, South Australia contributes up to one-seventh of Australia’s total wheat production.1
• Barley: This crop has gained significant importance, with the state producing approximately one-fourth of the national total.1
• Grapes: Viticulture is a major economic driver, with grapes accounting for about one-sixth of the value of the state’s primary farm commodities. South Australia contains more than two-fifths of the country's total vineyard area, with regions like the Barossa Valley serving as key contributors to the national wine industry.12
• Fruits and Vegetables: Intensive production of orchard fruits—particularly oranges—and various vegetables is common, often grown under irrigation in areas such as the Murray River districts.1

These commodities, alongside livestock production, form a significant portion of the state's primary industry.13
