Seed vitalisation

a revolutionary, ecological method with unique storability

As a result of years of extensive research to optimise techniques for improving seed quality, the head of Nelson Garden’s R&D department has developed a new revolutionary, ecological method. The invention makes it possible to achieve the benefits of seed priming while at the same time maintaining the vigour and germination capacity of the seeds over time.

The method, which works for most species, has been developed from laboratory scale to a prototype of a machine that can perform the seed vitalisation in a mechanical environment. This work was supported by the Swedish innovation agency Vinnova. Now Nelson Garden continue to scale up the equipment to commercially viable volulmes. Vitalised seeds will be marketed globally under the name Optigrow® and are aimed at both proffesional growers and hobby gardeners. The seed vitalisation also opens up new, excellent opportunities for the organic market.

Seed vitalisation

The seed vitalisation method enhances the germination performance. Vitalised seeds germinate faster and more uniformly than untreated seeds, and the germination capacity is often improved as well. There are many advantages with the Optigrow® seeds, such as:

• Superior shelf-life allows for long storage

• Faster emergence and earlier crop development

• More uniform crop stands

• More vigorous seedlings

• Stronger weed competition

• Improved germination and seedling emergence under sub-optimal conditions (unfavourable temperatures and deficiency or excess of soil moisture)

• Improved yield potential and quality of the harvest

• A method to overcome seed dormancy

 Early emergence and crop establishment may enable earlier harvest, or extend the growing season with possibilities for extra production cycles in fast crops and in transplant production. Improved germination capacity and more vigorous seedlings also increase the final population and percentage of usable transplants. Uniform crops facilitate crop management and in some crops also the harvest and quality of the harvested products. Vigorous seedlings are better equipped to cope with stress. The seed vitalisation washes away fungi and bacteria from the seed coat and reduces primary infections of seed-borne diseases. Stronger seedlings and healthier stands decrease the need for chemical crop protection. Strong weed competition and uniform crops favour efficient weed control and reduce the use of herbicides. These factors all contribute to improved productivity and profitability in plant production.

What makes the Optigrow® seeds unique?

The method Nelson Garden has developed is fully ecological and it does not only enhance the vigour, but also maintains seed storability over a long time. To distinguish this technique from current priming practices, the innovative, patent-protected method is called seed vitalisation. Competitive advantages with Nelson Garden seed vitalisation method compared to traditional priming:

• The vitalisation process is optimised to prevent deterioration of the seed quality over longer time. The unique shelf-life makes it possible to store vitalised seeds longer

• The vitalisation is conducted without adding any chemicals; with only water and air involved, the method is completely ecological and can therefore also be used for treating organic seeds.

• The process is both time- and resource efficient, which makes it commercially viable to treat a broader range of species and varieties from different market segments.
