Rice is an important cereal crop for over half of the world population and essential for food security, especially in developing countries where it constitutes a substantial part of daily caloric intake. Wood vinegar, obtained from biomass pyrolysis and rich in organic acids, phenols, esters, sugars, and alcohols, promotes crop growth and productivity. Its diverse composition offers an eco-friendly and cost-effective growth promoter and improves stress tolerance in different crops; however, its optimal application timings in rice cultivation remain underexplored. Our study investigated the effects of wood vinegar on rice growth, photosynthetic efficiency, chlorophyll contents, soluble sugars, phenolics, grain chalkiness, and yield at different stages and combinations such as tillering (T), jointing (J), flowering (F), grain filling (G), T + J, T + F, T + G, J + F, J + G, F + G, T + J + F, T + J + G, T + F + G, and J + F + G. Our results indicate that wood vinegar application at T + J + F stages significantly enhanced the photosynthetic rate by promoting gaseous exchange, chlorophyll contents, and SPAD index when compared with control. Additionally, total soluble sugars (9.71 mg g-1) and phenolics (2.4 mg g-1) levels were noticeably induced during wood vinegar application as compared with corresponding control. Besides, this treatment also elevated the yield by up to 32.4%, reduced grain chalkiness, and enhanced head rice percentage. Taken together, these findings suggest that wood vinegar supports sustainable agriculture by improving crop yield and quality, offering considerable benefits to farmers.

This study analyzed 5,166 research and review articles on the topic of soil pollution published up to July 20, 2024, including 72 top-cited papers. The publications, primarily written in English, originated from 129 countries or regions and appeared in 961 journals and five book series. The five most productive journals were Science of the Total Environment (298 articles, 5.77%), Environmental Science and Pollution Research (218, 4.22%), Environmental Pollution (162, 3.14%), Chemosphere (142, 2.75%), and Environmental Monitoring and Assessment (138, 2.67%). The top five contributing countries-China, Spain, the United States, Poland, and India-each published more than 275 papers. Using co-occurrence network visualization with VOSviewer, the keywords were grouped into seven distinct thematic clusters. In addition, the 25 keywords with the strongest citation bursts were identified through CiteSpace analysis. Most of the publications were aligned with three key Sustainable Development Goals: Sustainable Cities and Communities (SDG 11), Zero Hunger (SDG 2), and Climate Action (SDG 13). The findings of this study not only provide a comprehensive overview of the current state of research in soil pollution but also offer valuable guidance for shaping future research directions in this critical environmental field.

The present study aimed at investigating the beneficial effects of wood vinegar on yield and productivity of an indigenous rice cultivar (Wuxiangzhan). A pot experiment was conducted at the College of Plant Science and Technology, Huazhong Agricultural University, Wuhan, China by following randomized complete block design (RCBD) with 15 replications. Foliar application of 400-fold diluted wood vinegar was conducted at key rice growth stages such as tillering (T-1), jointing (T-2), flowering (T-3), grain filling (T-4), and application at all stages (T-5), with a control (C) receiving no application. Results showed highly significant effects related to foliar application of wood vinegar at aforementioned growth stages. Moreover, considerable trait variation was observed among the treatments based on a diverse pool of morpho-physiological and qualitative attributes. T-5 treatment significantly improved several morpho-physiological parameters (% increase over control) including total chlorophyll content (21.50%), leaf area (22.39%), and aboveground dry matter accumulation (14.19%). Likewise, photosynthetic parameters such as net photosynthesis and stomatal conductance were also observed to be maximized in T-5, with an increase of 17.97% and 33.33% respectively. Yield components including plant height, number of productive tillers, and grain yield were most enhanced in T-5, with a notable 28.77% in grain yield. Quality assessments revealed that wood vinegar application in T-5 also decreased chalkiness rate (19.27%) and amylose content (5.40%) while increasing head rice recovery (2.50%) and protein content (3.09%) thus optimizing rice quality. Cumulatively, in comparison to the control, rest of the wood vinegar treatments showed beneficial effects viz; T-5, T-1, T-2, T-3, and T-4. These findings demonstrate that wood vinegar, particularly when applied at all growth stages, can significantly enhance rice growth, yield, and quality. In conclusion, this research uncovered wood vinegar application as one of the sustainable and eco-friendly rice cultivation practices, contributing to global food security.
