Agriculture and its derived industries are still an important activity in the province, adding over 10% to output. Tobacco, sugar cane and viticulture are the most important and produce most of the exports from the area. Other crops mostly for local consumption are maize, beans, citrus, bananas, and tomatoes. The sugar cane is processed in plants in Salta before it is sent to the rest of Argentina and other countries. The plant in San Martín de Tabacal is the most important of them. The famous wines of the Valles Calchaquíes region (mainly Torrontés, Malbec and Cabernet Sauvignon) near Cafayate are produced in numerous vineyards of diverse sizes. American breeds of cattle are raised only on the humid subtropical east, along with some sheep and goats.
