In the context of sustainable agriculture, search for soil improvers that boost crop growth without harming biodiversity is gaining much attention. Biochar, solid residue resulting from pyrolysis organic material, has recently emerged as a promising bioproduct in enhancing yield, but there lack information regarding its effects on arable biodiversity. Thus, this study, we tested effect biochar application germination and seedling cornflower (Centaurea cyanus L., Asteraceae), threatened weed, under laboratory conditions. We investigated various parameters, including percentage (GP%), mean time (MGT), rate index (GRI), energy (GE%), fresh dry weight (mg) seedlings, radicle length (mm) treatments at different concentrations: 0% (control), 0.1%, 0.2%, 0.5%, 1%, 2%. Our findings revealed significant increase GP, GE, GRI concentrations 0.5% 1%. MGT slightly increased 0.1% biochar. Seedling was unaffected by application, whereas exhibited Radicle showed substantial day one, significantly higher 0.2% 1% two. However, three, no more statistically differences were observed between biochar-treated diaspores controls (i.e., had positive only first stages). These results suggest intermediate (0.5% 1%) overall provides most benefit to C. cyanus.

This study investigated if the foliar application of wood distillate (WD, a by-product biomass pyrolysis, containing bioactive compounds, including organic acids and phenols) influences some key parameters (fresh weight, photosynthetic efficiency, antioxidant stress-related biochemical markers, mineral content) basil plants, used as model crop, grown under water-limited conditions. The experimental setup included control WD treatments (applied via at 0.2%) three drought levels: no stress, moderate, high stress. results indicated that contributed to improving fresh chlorophyll, reduced oxidative stable levels essential nutrients across varying intensities. These outcomes highlight potential an effective biostimulant for enhancing tolerance in plants water deficiency.
