Effective microorganisms improve the quality of tomato transplants, as they remained more compact with a greater stem diameter.

Effective microorganisms influence tomato transplants to be shorter with thicker stem, that allows to uptake more nutrients by tomato plants

Problem: What problem is this initiative trying to address?

Tomato plants during transplant age tend to be elongated, which causes that quality of transplants will be bad at planting age. Therefore the purpose was to see whether the effective microorganisms could improve the quality of tomato transplants.

Solution Summary: What is the proposed solution? What do you see as its most promising aspects for creating shared value?

The proposed solution was to treat plants with effective microorganisms. We got amazing results: Plants were shorter it means that nutrients flow more quickly to the top of plants and plant is strong, because of higher nutrient content (especially Ca and Mg content, which elements make plant stronger). Plants had greater stem diameter, which means that plant can take up more nutrients at the same time. As the result the quality of transplants was very good, they were compact (not elongated), strong and having greater stem diameter.

Impact: What is the impact of the work to date? Specify both the social and the environmental impact of your work

Social impact: Golden rule in tomato production is that the better is the quality of transplants the better is yield of tomato plants after transplanting. Environmental effect: Plants were shorter it means that nutrients flow more quickly to the top of plants and plant is strong, because of higher nutrient content (especially Ca and Mg content, which make plant stronger). Plants suffer fewer diseases and insect attacks. In plant nutrition, calcium is often referred to as the plant’s first line of defence. Increased calcium levels in leaf tissue can greatly decrease the pathogen’s ability to invade the leaf. Adequate levels of calcium in plants also aid the plant’s ability to isolate an infection. A plant grown in these conditions contains more calcium, i.e. has better storability. Plants containing more calcium have strong cell walls.

Financial sustainability plan: How is this initiative financially supported? How will you ensure its financial sustainability long-term?

1. Individual donations or gifts - no 2. Grants - ECRI supported this research. 3. Corporate contributions - no 4. Earned income - no 5. Other - others have tried it out after my methodology. System is very easy to use. Risk involved is thet by using not right methodology farmers will not get the same results. Very important to use RIGHT METHODOLOGY. The system is very simple, does not need new equipment or investing, to existing greenhouse. Easily replicable globally. I would like to start large scale experiments in order to showcase the method to farmers and other stakeholders.

Unique value proposition: What makes your initiative innovative? How does your project differ from other organizations working in the same field?

This discovery is innovative because it has solved one important problem: elongation of tomato plant. There are several methods to keep plant short, as well as negative DIF, far red filter, etc., but the advantages of Effective microorganism method is that STEM DIAMETER IS ALSO INCREASED and plants are stronger.

Founding story: Share a story about the "Aha!" moment that sparked the beginning of this initiative.

I heard that one of my colleagues had a problem with tomato transplants that they are elongated and with bad quality, especially variety Valve. I thought that a product effective microorganisms could be a solution because of it's capability to increase the bio-diversity of soil microflora, thereby increasing crop yield. Photosynthetic bacteria, the major components of EM, which work synergistically with other microorganisms to provide the nutritional requirements of the plant and to reduce disease. It interact with the soil-plant ecosystem to suppress plant pests and diseases, to solubilise minerals, to conserve energy, to maintain soil microbial-ecological balance, to increase photosynthetic efficiency, and to fix biological nitrogen.

Thank you very much for such a positive feedback. Unfortunately I do not have patent. Yes, the research is possible to transform into a business model to replicate.
