• Abstract: -It is essential to incorporate organic amendments such as compost and bokashi in sustainable agricultural systems at the farm level. However, the potential benefits of using biochar as an additive in bokashi have not been previously studied. Therefore, this research aimed to explore the effects of biochar on the agronomic and environmental aspects of bokashi and compost production. To achieve this, a field experiment was conducted, comparing bokashi and compost piles with and without biochar. During the maturation process, various parameters including temperature, chemical composition, and biological changes were monitored. The findings demonstrated that the inclusion of biochar in both types of amendments helped regulate the maximum temperatures reached during the process. Moreover, bokashi and compost piles with biochar exhibited higher pH levels and lower CO2 emissions during maturation; and bokashi with biochar showed increased forage productivity. In conclusion, the use of biochar had a positive impact on the maturation process and overall quality of bokashi and compost. This has significant advantages for agriculture and organic waste management, as it enhances performance for crops and offers practical applications.
