Two experiments were designed, one with biochar powder and another with biochar water extract to mimic the environmental conditions of the growing season of the crops. The findings of the study revealed that the seeds of pulse crops responded slower during the initial days (3 to 7 days) of exposure to the biochar powder whereas a marked increase in root and shoot growth parameters was observed with increasing doses of biochar at 15^th day, compared with the control. With an initial increase in growth behaviour of pulses (at 3^rd day), a stable growth response was observed at 7^th and 15^th days under control treatments. Both cereal and pulse crops showed better growth responses with increasing dose of biochar, and maximum growth was observed at 1-2% (for powder) and 2-4% (for extract) biochar doses. Application of powdered biochar showed better growth responses than the extract, as it facilitated gradual-release of nutrients, thus allowed the plants to stay healthy for a longer period of time. The results underscore the importance of using biochar based on the specific crop types, seed sizes, and growth stages to fully utilize its potential in sustainable agriculture. Harnessing the beneficial attributes of biochar not only enhances soil quality and crop yields but also presents a promising avenue for environmentally friendly weed control and resource utilization, aligning with broader objectives of agricultural sustainability and food security. Further investigations focused on optimizing biochar formulations and conducting field-scale trials will be essential in realizing its transformative impact on global agricultural practices.Top of Form https://www.agriculturejournal.org/volume12number2/assessing-the-potential-of-biochar-derived-from-tropical-deciduous-tree-broussonetia-papyrifera-for-crop-improvement/ Carbon; Cereals; Invasive species; Legumes; Nutrients; Plant growth
