Chemical fertilizers are the primary source of crop nutrition; however, their increasing rate application has created environmental hazards, such as heavy metal toxicity and eutrophication. The synchronized use chemical eco-friendly biological tools, microorganisms biochar, may provide an efficient foundation to promote sustainable agriculture. Therefore, current study aimed optimize nutrient uptake using inorganic fertilizer, sulfate potash (SOP) from plant growth-promoting fungus Bipolaris maydis AF7, biochar under conditions in rice. Bioassay analysis showed that AF7 high resistance metals a tendency produce gibberellin, colonize increase intake free amino acids. In experiment, co-application +Biochar+MNF+SOP significantly lowered toxicity, enhanced rice shoots, improved morphological attributes (total biomass). Moreover, augmented glucose sucrose levels, whereas it endogenous phytohormone levels (salicylic acid jasmonic acid) shoots. content aligns with higher expression OsLSi6, PHT1, OsHKT1 genes. growth traits tolerance were validated by whole-genome sequencing presence detoxification protein, siderophore iron transporter, Gibberellin cluster GA4 desaturase, DES_1 genes, well others regulate glucose, antioxidants, Because +biochar+inorganic fertilizer works synergistically, availability crops could be improved, hazards minimized.

Cadmium stress significantly affects plant growth by disrupting essential physiological and biochemical functions. It slows nutrient intake, causing slowed development decreased biomass. Cd also produces reactive oxygen species, oxidative stress, which harms cell components like lipids, proteins, DNA. This lowers chlorophyll levels, making photosynthesis difficult stunting development. Cd's toxicity hormone balance, enzyme activity, structural integrity, leading to poor agricultural output. Acidified biochar (BC) can effectively overcome this problem. Biochar features high cation exchange capacity (CEC) oxygen-containing functional groups may aid in the immobilization of heavy metals soil via surface complexation precipitation. be increased treating with acid, exposes additional adsorption sites. enhance improving structure, encouraging water retention, microbial activity as a slow-release nutrient. study investigates effects combining BC amendments spinach, both without stress.
