Contextualization: Pea is a commercially important legume in Colombia that is distinguished for its nutritional content. Therefore, it is relevant to search for strategies to improve pea yield sustainably with the environment under several conditions.

Knowledge gap: The effect of multiple plant growth-promoting microorganisms (PGPM) on the Santa Isabel pea variety under different irrigation conditions is unknown.

Purpose: To determine the effect of the microorganisms Bacillus amyloliquefaciens, Pseudomonas fluorescens and Trichoderma koningiopsis on the growth and yield of pea (Pisum sativum L.) in optimal water conditions and under water stress.

Methodology: A factorial design was carried out where seed inoculation with Bacillus amyloliquefaciens, Pseudomonas fluorescens and Trichoderma koningiopsis or the absence of these and the application of irrigation during the crop growth cycle of 50 %CC and 100 %CC were evaluated.

Results and conclusions: PGPM inoculated on seeds of the variety Santa Isabel does not diminish the effects of water stress at 50 %CC. Pea seeds inoculation with Pseudomonas fluorescens is promising under more favorable irrigation conditions (100 %CC) by increasing root dry weight, irrigation use efficiency and both green and dry yield.
