Identification of Bacteria That Promote Plant Growth with Low Fertilizer Inputs.

The Need: Enhancing Greenhouse Ornamental Crop Production with Plant Growth Promoting Rhizobacteria (PGPR)

In the competitive and environmentally-conscious market of greenhouse ornamental crop production, the need for sustainable and efficient cultivation methods has become increasingly paramount. Traditional practices rely on high fertilizer inputs to meet production deadlines and quality standards, which, in turn, can lead to reduced plant stress tolerance and negative environmental impacts. To address this challenge, a revolutionary technology has emerged, leveraging the potential of Plant Growth Promoting Rhizobacteria (PGPR) to significantly improve plant performance and nutrient use efficiency, thereby reducing the dependency on excessive fertilization.

The Technology: Plant Growth Promoting Rhizobacteria (PGPR)

Plant Growth Promoting Rhizobacteria (PGPR) are a collection of beneficial bacteria found in the rhizosphere of ornamental greenhouse crops. These specialized bacteria have demonstrated the remarkable ability to enhance plant growth, stress tolerance, and nutrient uptake. Through high throughput greenhouse trials and whole-genome sequencing, 15 top-performing PGPR strains were identified, including the impressive Enterobacter sp. C7B12, Pantoea dispersa C2H3, and Herbaspirillum huttiense C3B1. These selected strains have shown exceptional potential in improving multiple parameters of plant performance under low fertility conditions, leading to the production of high-quality ornamental crops with reduced fertilizer rates.

Commercial Applications:

The groundbreaking technology of Plant Growth Promoting Rhizobacteria (PGPR) finds versatile applications across the commercial horticulture industry, including:

  • Enhanced Greenhouse Ornamental Crop Production: Improving plant performance, flowering, and vegetative growth, allowing greenhouse growers to produce premium ornamental crops with reduced fertilizer inputs.
  • Sustainable Horticulture Practices: Addressing environmental concerns by decreasing the negative impacts of excessive fertilization, leading to greener and eco-friendly crop cultivation.
  • Increased Nutrient Use Efficiency: Optimizing nutrient uptake and utilization by plants, resulting in cost savings for greenhouse operations and improved resource management.


The adoption of Plant Growth Promoting Rhizobacteria (PGPR) technology offers several advantages to greenhouse ornamental crop producers:

  • Reduced Fertilizer Dependency: PGPR application allows for significant reductions in fertilizer rates without compromising crop quality, leading to cost savings and sustainable practices.
  • Enhanced Plant Performance: The selected PGPR strains have shown consistent improvements in flowering, vegetative growth, and vegetative quality, ensuring the production of visually stunning and healthy ornamental crops.
  • Improved Stress Tolerance: PGPR helps enhance plant stress tolerance, resulting in increased resilience to adverse environmental conditions, thereby minimizing crop losses and enhancing overall yield.
