Agriculture accounted for 85% of total employment (formal and informal) for 2000. Maize (corn) is the principal cash crop as well as the staple food. Other important crops include soybean, cotton, sugar, sunflower seeds, wheat, sorghum, pearl millet, cassava, tobacco and various vegetable and fruit crops. Floriculture is a growth sector, and agricultural non-traditional exports now rival the mining industry in foreign exchange receipts. Zambia has the potential for significantly increasing its agricultural output; currently, less than 20% of its arable land is cultivated. In the past, the agriculture sector suffered from low producer prices, difficulties in availability and distribution of credit and inputs, and the shortage of foreign exchange. In 2019 Zambia produced: 4.7 million tons of sugarcane; 4 million tons of cassava (18th largest producer in the world); 2 million tons of maize; 281 thousand tons of soy; 153 thousand tons of tobacco (6th largest producer in the world); 151 thousand tons of wheat; 130 thousand tons of peanut; 109 thousand tons of sweet potato; 72 thousand tons of cotton; 6,900 tons of coffee; In addition to other productions of other agricultural products.
