Abstract Background Reductive soil disinfestation (RSD), which involves creating anaerobic conditions and incorporating large amounts of organic materials into the soil, has been identified as a reliable strategy for reducing soilborne diseases in successive cropping systems. However, limited research exists on connections between microorganism composition plant under various types material applications. This study aimed to evaluate effects distinct RSD strategies (control without amendment; with 1500 kg ha −1 molasses powder; 3000 powder 37.5–41.3 microbial agent) disease index, bacterial community network structure rhizosphere soil.

Tobacco (Nicotiana tabacum) black shank disease, caused by Phytophthora nicotianae, is a significant threat to tobacco crops, leading severe economic losses. Prolonged use of agrochemicals control this disease has prompted the exploration eco-friendly biological strategies. This study investigated effects Trichoderma harzianum, biocontrol agent, on N. tabacum in comparison P. focusing growth, biomass, root morphology and anatomy, hormonal changes, osmotic regulation. T. harzianum significantly enhanced plant biomass accumulation, system development, physiological attributes such as photosynthetic pigment levels antioxidant enzyme activity. In contrast, nicotianae negatively impacted these parameters, inhibiting growth function. Notably, increased proline content induced resistance mechanisms, mitigating stress promoting overall health. These findings highlight potential sustainable solution for managing while improving crop productivity.
