Soil leveling off was occurred all over the world due to high intensity use of crop production.  An appropriate strategy to overcome this soil problem was needed. The main problem of using Ultisols is the limiting factors of physical, chemical and biological properties that are not favourable to crops, therefore the application of sustainable technology is recommended. The main objective of this paper were to describe the response of peanut growth and yields using biotechnology Bokashi plus and to identify the best peanut varieties that are responsive, adaptive and potentially high yield. The method used was experimental method, with seven different peanut types collected in SE region and planted in Muna regency using Split Plot Design. Bokashi plus was applied with four levels, i.e; 0, 6, 12 and 18 t ha$^{-1}$ with three replications, so that there were 72 experimental units. Growth components at 14, 28, 42 and 56 days after planting were recorded, such as plant height, number of leaves, stem diameter, leaf area and biomass dry weight of peanut. Vegetative variables observed were plant growth and nutrient uptake, yield components and analysis nutritional content of seeds. The results showed that the application of biotechnology Bokashi plus gave a significant effects on the growth and yields components of seven peanut cultivars of local superior as the indication of increasing soil quality on physical, chemical and biological properties in Ultisols. It was concluded that the higher the dose of biotechnology Bokashi plus applied might improve the growth components and peanut yield, although further bokashi plus doses tested showed the difference was not significant.  Higher yield of peanut was up to 3.67 t ha$^{-1}$ as the indication of positive response of peanut due to the increasing macro nutrients content, like N, P, K and other micro elements into soil that might improve peanut yields and increase world community welfare.}
