Fungi, particularly Pleurotus eryngii, emerges as a promising solution for sustainable non-animal protein production, requiring less land and growing on waste materials. In connection with population growth, solutions must be found to increase yield product quality without resorting the use of synthetic chemical fertilizers. Several biobased products are currently market; one most interesting is wood distillate (WD), derived from pyrolysis process woody material. WD rich in biologically active substances such polyphenols, alcohols, acids, esters, its authorized organic agriculture. The study investigates cultivating P. eryngii. We tested different concentrations WD: 0%, 0.1%, 0.2%, 0.5%, 1% growth Although did not significantly affect (fresh weight), it led substantial total soluble content antioxidant compounds, phenols vitamin C, reduction glycogen content, especially at 0.2% WD. results highlight potential biostimulants mushroom cultivation, providing ground further research improve nutritional properties cultivated mushrooms through distillate.

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.

This study explores the potential of honey as a natural soil amendment to enhance plant growth and biochemical resilience in Ocimum basilicum L. Honey solutions at varying concentrations (2.5%, 5%, 10%) were applied evaluate their effects on parameters, biomass accumulation, antioxidant activity. The results revealed that lower (2.5%) had minimal impact height, while higher (5% 10%; −42% −43%, respectively) exhibited inhibitory effects, suggesting dose-dependent response. leaf count remained stable across treatments, indicating consistent morphological outcome. analysis highlighted variability biomasses, reflecting influence energy allocation. Despite unchanged chlorophyll ascorbic acid levels, significant enhancements compounds activity observed, particularly (antioxidant 2.5% 5%; +26% +30%, respectively), underlining role bolstering defense system. These findings demonstrate honey’s dual modulator enhancer, emphasizing its relevance sustainable agricultural practices. research contributes development eco-friendly strategies for improving crop performance through application naturally derived biostimulants.

Abstract The present work investigated the effects of different doses biochar (2.5%, 5%, 10%), a by-product pyrolysis woody biomass, on growth oat plants ( Avena sativa L., cv “Danko”) grown under crude oil concentrations (0.5%, 1%, 2%, 3%, 6%) added to soil, evaluating both biometric (i.e. fresh weight) and biochemical i.e. , content malondialdehyde proline, total antioxidant power) parameters. findings indicate that positively influences weight across all investigated. On other hand, regarding oxidative stress, measured by proline content, led significant reduction, with statistical significance observed at > 2.5% levels 2% (malondialdehyde: ranging from -25% -38%; -33% -52%). Soil amendment increased power, particularly (ranging + 20% 98%). These results suggest has great potential in mitigating negative contamination plant stress levels, thereby highlighting its value as conditioner contaminated soils.
