Multifactorial formulation for stable encapsulated plant growth promoting microorganisms.

ABSTRACT: The effectiveness of plant growth-promoting microorganisms (PGPMs) in agriculture depends on their formulation into stable, viable products. This study evaluated the stability and viability of three PGPMs-Trichoderma harzianum I 20, Pseudomonas fluorescens P-187, and Bacillus subtilis SWRIs-using various carrier-based and encapsulation formulations. A factorial experiment was conducted with eight formulations, stored at room and cold temperatures for up to six months. Significant interactions between formulation type, storage temperature, and duration were observed (p < 0.01). After six months at room temperature, the biochar-trehalose-glycerol formulation maintained the highest populations for all three microorganisms. At cold room temperature, this formulation also provided the greatest
