A research was carried out to study the morphophysiological response of cocoa plant leaves to different application of microbes formulation in the farmer’s cocoa plantations in Gantarangkeke village, Gantarangkeke district, Bantaeng Regency, South Sulawesi Province from July to December 2016. The experiment was set using Randomized Block Design with nine combinations of dosages and frequencies of the application of microbe formulation as treatments. The formula was sprayed on cocoa leaves using bio-mineral liquid fertilizer with dosages of 0.5, 1.0, and 1.5 mL.L -1 applied once, twice and three times during the experiment. The first application was at the start of the experiment, and the second was at the age of 2 months after planting, respectively. For the three times application treatment, plants were sprayed by the formula every two months. The experiment used three replications, and each experimental unit consisted of four selected plants which were relatively uniform. Results show that the application of microbial formulations through leaves could increase some morphophysiological properties of the leaves of cocoa plants. The application of microbial formulations of 1.5 mL.L -1 of water every two months during the study showed an increase in leaf area growth, leaf water content, chlorophyll a, b and total chlorophyll content of cocoa leaves.
