In Suriname groundnuts are grown on sandy ridges in the coastal area. Farmers' plots are small. Labour is scarce and the possibilities for mechanization are limited. As a result the total groundnut acreage is gradually decreasing. Large areas of sandy soil occur immediately south of the coastal clay belt. They vary in texture from sands to sandy loam and seem suitable for mechanized crop production. The potential of these soils, particularly the sandy loams, for annual crops is being studied in an experimental farm named Coebiti. One of the crops is groundnuts of which various agronomic aspects have been studied so far. The present paper summarizes the main results of experiments on the subjects of liming, plant density and spacing, and Cercospora leaf spot control, that were carried out in the period 1972-1975.
