摘要

Because of their exceptional environmental tolerance, ability to spread, and quick rate of reproduction, invasive plants are harmful to both human health and ecosystems. Hence, the current research was carried out to evaluate the possible utilization of invasive plant biomass by converting it into a beneficial soil supplement biochar. The biochar derived from three invasive plants (Ageratina adenophora, Lantana camara, and Parthenium hysterophorus) was applied at four application rates (1, 3, 5, 7 g kg−1 soil) and a control without biochar. Ten seeds of test crop Lens culinaris were sown in each pot. A variety of traits, including seed germination, growth, biomass, and reproductive indices, were determined. The biochar inhibited the seed germination rate (GR) and percentage (GP) across all the feedstock types and application rates while showed stimulating effects on growth parameters. Shoot length (SL), total plant length (TPL), shoot volume (SV), total biomass (TB), root moisture content (RMC), and seed vigor index (SVI) were all significantly (p < 0.05) impacted by feedstock types and application rates. On the other hand, SL, TPL, TB, and RMC were significantly affected by the application rates only. The application of biochar from invasive species negatively affected germination percentage and germination rate in Lens crops, likely due to nutrient immobilization in initial stage. The study concluded that P. hysterophorus biomass-derived biochar outperformed biochar produced from two other invasive plant species, highlighting the significant role of feedstock type in determining the characteristic and nutrient content of biochar. This finding underscores the potential of utilizing invasive plant species as a sustainable feedstock for biochar production. By converting invasive plant biomass into biochar, it is not only possible to mitigate ecological imbalances but also to enhance agricultural productivity through improved soil nutrient content thus, presents a promising approach to address both ecological and agricultural challenges.
