PGPR compositions for enhanced growth of tomato and potato crops

Overview

This innovative technology leverages a specific formulation of plant growth-promoting rhizobacteria (PGPR) to significantly enhance the growth and productivity of tomato and potato crops. The solution utilizes a defined mixture of bacterial strains, including Burkholderia phytofirmans PsJN, Burkholderia phymatum STM815, and Azospirillum brasilense Sp7, each contributing approximately 30% to 40% of the total bacterial concentration. This PGPR composition is applied either to the seeds or to the soil, offering a simple yet effective means to boost crop yield and health.

Technical specifications
