In order to study the effect of bioactivator application to accelerate the production of compost from sugarcane wastes, an experiment was conducted as a complete randomized design with four replications in Safiabad Agricultural Research and Education and Natural Resources Center in 2020 (for one year). The treatments included: control (bagasse without the use of bioactivator) and the second to fourth treatment were the application of 0.5, 1 and 1.5% by weight of bioactivators in 100 kg bagasse, respectively. The results showed that, there was a significant difference between treatments at significance level of 5% in the terms of electrical conductivity (EC), organic carbon (OC), C/N (in sampling after 45 days) and Fe and Mn concentrations (in sampling after 60 days). Furthermore there was a significant difference between treatments at the level of 1% in terms of OC, C/N and Cu concentration (in sampling after 60 days). Studies also showed that the highest temperature (52 °C) was measured in 1.5 % treatment and the highest EC was measured in sampling after 45 days in 1% treatment (3.02 dS/m). The highest OC and C/N, were measured in sampling after 60 days (43.9% and 34.4) in 1.5 % treatment, respectively. Regarding the amount of elements in the final compost (in sampling after 60 days), the highest amount of Fe concentration (4581.5 mg. kg-1) was measured in 1 % treatment, Cu (15.25 mg. kg-1) and Mn (72.25 mg. kg-1) were measured in 1.5 % treatment and no significant difference was observed among the treatments in terms of nitrogen, phosphorus, potassium and zinc (Zn) concentrations at significance level of 5%. According to results of this study, the 1.5% treatment increase the speed and quality of compost produced from sugarcane waste (bagasse).
