Abstract

The results of the previous year study found that the somatic embryogenesis (SE) cocoa plant originated from planting from year 2009 until 2012, has not been in its optimal growth and production. It is reported is a significant mortality rate in the cocoa plant nursery phase or the SE in the vegetative phase. Based on the data and information, it is known that there is a need for the engineering efforts to increase production and quality of SE cocoa through the application of bud grafting and side grafting. The assessment is also expected to support farmer in order to apply the technology of bud grafting and side grafting for SE cocoa plant. The purpose of this study are : a) to find out the improvement of crop productivity and quality of SE cocoa through bud grafting and side grafting, and b) to analyze the response of farmers to increase crop productivity and quality SE cocoa through bud grafting and side grafting. This study was conducted in Bone, and Luwu regency, South Sulawesi from January 2015 to December 2016. This study used a Randomized Block Design with 8 treatments and 4 replications. Data collected are SE cocoa populations, some problems of SE cocoa developments and social-economic of farmers. Plant observations include growth and productivity of cocoa. The data has been collected, tabulated described and analyzed by ANOVA and Duncan’s Multiple Range Test (level 5%). SE cocoa plants have high jorget, small pod, small beans and flat. Productivity of side grafting cocoa is 4.21-4.36kg/tree/year. Response of farmers can receive bud grafting and side grafting technology for SE cocoa plant.
