Application

Chemical fertilizers are environmentally hazardous. Using plant growth promoting bacteria, and specifically plant growth-promoting rhizobacteria (PGPR) has a great potential in bio-fertilization. The combination of two PGPR bacterial species effectively colonize plant roots and enhance their growth. The positive effect of these combined bacterial species was proven in the laboratory, greenhouse and field conditions.  The PGPRs unique combination enabled 15% growth in plant yield when tested on cucurbits (melons). The effect was achieved under standard commercial conditions in the field, including optimized fertilization.

Our Innovation

  • Environmentally-friendly biofertilizer
  • Increased root growth and plant yield in comparison to untreated plants
  • Positive results in various growing conditions (paper pouches ,greenhouse and field)
  • Positive effect was especially noticeable under stress conditions
  • Combination may be used as Herbicides / Pesticides

Technology

The proposed technology is an environmental-friendly biofertilizer composed of a unique combination of two bacterial species.

 

Expected Impact

  • The main goal of the research group is to produce an environmental-friendly biofertilizer that could effectively decrease the use of chemical fertilizers and/or help plants coping with stress while still increasing crop yield.
  • Our biofertilizer will be further expanded to use for grains and legumes, in which cutting chemical fertilizer costs is of great interest.
  • Growing demand of the organic food market, and awareness to environmental matters is expected to increase the use of alternative non-chemical and environmentally-friendly biofertilizers.

Development Stage

TRL5 Technology validated in relevant environment. Next phase of the research is to estimate the success of the combined bacterial species to improve growth of additional plants. Experiments will be carried out in the greenhouse and in the field.
