The type of agriculture engaged in--whether cash crop, subsistence, or a combination thereof--varied from region to region and within regions. In the central plain, there were farmers whose sole activity was the raising of such cash crops as maize, sugarcane, vegetables, and fruit. In the rice bowl region of the central plain, farmers grew rice for sale as a main crop. Elsewhere, rice was raised basically for subsistence purposes, but many farmers also cultivated secondary crops for the market. In areas without developed access roads and services, such as parts of the upper Northeast, participation in the market economy was limited. Farmers in these areas practiced subsistence cultivation, selling only an occasional surplus locally.
