Plant growth promoting rhizobacteria (PGPR) are a group of beneficial soil bacteria that play a vital role in enhancing plant growth and development. These bacteria colonize the root surface or the rhizosphere of plants and provide a range of benefits to the plant host. The use of PGPR is an eco-friendly approach to agriculture and has gained significant attention in recent years due to its potential to reduce the use of synthetic fertilizers and pesticides. PGPR have several mechanisms of action that enable them to promote plant growth. These mechanisms include the production of plant growth-promoting hormones such as auxins, cytokinins, and gibberellins. These hormones stimulate cell division, elongation, and differentiation, leading to increased plant growth. PGPR also produce enzymes that break down organic matter in the soil, releasing nutrients such as nitrogen, phosphorus, and potassium that are essential for plant growth .
In addition, PGPR can also protect plants from diseases and pests by producing antimicrobial compounds and inducing systemic resistance. These bacteria can also improve soil structure and water-holding capacity, leading to improved nutrient uptake by plants. PGPR can also promote the establishment of beneficial mycorrhizal fungi, which further enhance nutrient uptake by plants. There are several types of PGPR, including rhizobia, which are nitrogen-fixing bacteria that form symbiotic relationships with legumes. Other types of PGPR include phosphate-solubilizing bacteria, which help plants to access phosphorus, and plant growth-promoting rhizobacteria that produce phytohormones and improve soil structure. The use of PGPR has several advantages over the use of synthetic fertilizers and pesticides. Firstly, PGPR are natural and safe for the environment and do not cause harm to non-target organisms. Secondly, the use of PGPR can reduce the use of synthetic fertilizers and pesticides, leading to cost savings for farmers and reduced pollution of waterways. Thirdly, PGPR can promote sustainable agriculture by improving soil health and reducing the need for inputs such as fertilizers and pesticides .
The application of PGPR can be done through several methods, including seed treatment, foliar spray, soil drench, and inoculation of planting material. The selection of the appropriate PGPR strain for a specific crop and soil type is crucial for successful application. Several commercial products are available that contain PGPR and can be used as biofertilizers and biopesticides. PGPR are a group of beneficial soil bacteria that play an important role in promoting plant growth and development. The use of PGPR offers several advantages over synthetic fertilizers and pesticides and can promote sustainable agriculture. The application of PGPR requires careful selection of the appropriate strain and method of application, and the use of commercial products can simplify the process. The continued research and development of PGPR-based products will be essential for the advancement of sustainable agriculture .
The use of PGPR has gained significant attention in recent years due to its potential to address the challenges of global food security. The world's population is expected to reach 9.7 billion by 2050, and the demand for food is projected to increase by 70%. This increase in demand for food will require a significant increase in agricultural productivity. However, the use of synthetic fertilizers and pesticides has led to several environmental problems such as soil degradation, water pollution, and the loss of biodiversity. Therefore, there is a need for eco-friendly approaches to agriculture that can promote sustainable food production .
PGPR-based products have been shown to improve crop yields and quality in several crops, including cereals, vegetables, and fruits. These bacteria have been demonstrated to increase plant growth and development under various stress conditions, including drought, salinity, and heavy metal toxicity. The use of PGPR has also been shown to increase the nutrient-use efficiency of plants, leading to reduced fertilizer application rates.
The use of PGPR can also contribute to the mitigation of climate change. The excessive use of synthetic fertilizers leads to the release of greenhouse gases such as nitrous oxide, which contributes to global warming. The use of PGPR can reduce the need for synthetic fertilizers and reduce the emission of greenhouse gases. In addition, PGPR can enhance carbon sequestration in soils by improving soil health and increasing plant biomass. Several research studies have been conducted to investigate the efficacy of PGPR-based products. These studies have shown that the use of PGPR can increase crop yields by up to 30% and reduce the use of synthetic fertilizers by up to 50%. In addition, the use of PGPR has been shown to improve soil health and increase the diversity of soil microorganisms, leading to enhanced ecosystem services.
The use of PGPR-based products has several challenges that need to be addressed. The selection of the appropriate PGPR strain for a specific crop and soil type is crucial for successful application. In addition, the efficacy of PGPR-based products can be influenced by several factors such as soil pH, temperature, and moisture. Therefore, there is a need for continued research to optimize the use of PGPR-based products. PGPR is a promising approach to address the challenges of global food security and promote sustainable agriculture. The use of PGPR-based products can improve crop yields, reduce the use of synthetic fertilizers, and contribute to the mitigation of climate change. However, the application of PGPR requires careful selection of the appropriate strain and method of application. The continued research and development of PGPR-based products will be essential for the advancement of sustainable agriculture .
Plant growth promoting rhizobacteria (PGPR) are a group of beneficial soil bacteria that have shown great potential in promoting sustainable agriculture. These bacteria can enhance plant growth and development, improve soil health, and reduce the use of synthetic fertilizers and pesticides. The use of PGPR-based products can contribute to addressing the challenges of global food security and mitigate the environmental problems associated with the excessive use of synthetic inputs.
