      Abstract
      Gantarang Subdistrict is one of the largest cocoa land areas in Bulukumba Regency, South Sulawesi. However, the production of cocoa plants in Gantarang District is not optimal. Therefore it is necessary to evaluate the characteristics of cocoa land to establish the basis for determining the suitability of land for cocoa plants in the District Gantarang. The study was conducted using purposive sampling survey method through the collection of primary data and secondary data. Data obtained were analyzed using the matching method between land quality and land characteristics as parameters with the criteria of land suitability class. The results showed that the characteristics of land in Gantarang sub-district varied greatly. Namely temperature 26.5oC, rainfall 1848.30 mm / year, dry month as much as 2.6 months / year, soil drainage is somewhat poorly to well drained, soil texture are loam, clay and silt with soil depth moderately deep to deep soil depth, medium to high exchange CEC with high base saturation, soil pH is neutral, C-Organic and N total are very high, P2O5 is very low to high and K2O is relatively low, flat to moderately slopes, erosion hazard is very low to medium, flood hazard is very low, and medium surface stoniness and rock outcrops. The current suitability for cocoa plants in Gantarang Subdistrict at the subclasses level based on FAO criteria varies greatly. Based on the sub-class level there are 5 actual land suitability classes namely S3rc, S3nr, S3na, S3eh, and Nrc. Improvements that can be made are add organic matter, fertilizers, creating terrace and conservation. After improvement, the potential suitability class that can be achieved are S2, S3, dan N, which means that it is Moderately Suitable, Marginally Suitable, and Not Suitable with the most limiting factor is rooting condition, others by erosion hazard and land preparation.
