- Abstract
Agriculture plays a dual role in climate change, acting both as a source and a potential sink for greenhouse gas emissions. Achieving net zero emissions requires innovative farming practices that not only sustain crop productivity but also enhance carbon sequestration. This study investigates the effects of different rates of biochar (5%, 10%, 15%) and EM (1%, 3%, 5%) on the growth and yield of Jack Bean (Canavalia ensiformis (L.) DC.) cultivated in topsoil amended with EFB compost (4:1 ratio). Growth and yield parameters, including plant height, number of leaves, branches, flowers, and pods, were measured. These findings reveal that biochar, particularly at a 10% concentration, significantly improves plant height (up to 177.20 cm), number of leaves (40.03), number of branches (13.00), and number of pods (3.13). These enhancements demonstrate biochar’s potential to boost crop yields while simultaneously contributing to carbon sequestration in soil, thereby reducing atmospheric carbon and supporting climate mitigation efforts. Similarly, EM applications, especially at 5%, stimulated vegetative growth, resulting in a significant increase in the number of leaves (39.83), branches (15.30), and flowers (7.93). While EM did not significantly impact pod formation, its marked effect on plant vigor suggests its role in promoting plant health and potentially reducing reliance on synthetic agrochemicals. This aligns with sustainable agricultural practices that aim to minimize the use of energy and application of conventional fertilizers, thereby decreasing greenhouse gas emissions. The results demonstrate that both biochar and EM can serve as valuable amendments in agricultural systems. Integrating these sustainable biological and material inputs represents a promising approach towards achieving higher agricultural output within a net-zero emission framework.
