Biochar as a Possible New Alternative in the Propagation Medium of Olive Cuttings

Abstract

W ITHIN the framework of using organic waste in line with sustainable development, which helps reduce carbon emissions and overcome pollution resulting from burning these wastes while also lowering the cost of purchasing peat moss imported from abroad, this investigation aimed to study the possibility of using biochar as a good alternative to peat moss in the olive propagation medium, which helps in achieving the previous goals. Therefore, during the 2021 and 2022 seasons, cuttings of Coratina, Manzanillo, and Picual cultivars were used to find out the success of their propagation in biochar media. Where 5 ratios of biochar to sand were used to achieve the following ratios,
