Organic cucumber growers operate with a narrow margin for error. Production must remain efficient, but there is limited room for quick corrections. Plant resilience, nutrient uptake, and crop balance must therefore be just right from the start.
In the spring of 2025, Jodoco tested Floraboost at an organic cucumber farm in Antwerp. This was not a small-scale demonstration, but a field trial conducted under commercial greenhouse conditions.
The result: a 5.8% increase in yield. That translates to 24,000 additional cucumbers per hectare.
Field Trial at Organic Grower Van Hauteghem’s Farm
The trial took place at Van Hauteghem, an organic grower that has been committed to sustainable, soil-based vegetable cultivation since 2016.
The cucumber plants were planted in late January as 10-cm-tall seedlings. They were grown in a 2-hectare greenhouse equipped with CO₂ injection and a combined heat and power (CHP) system. This allowed the plants to grow under favorable conditions and made the effect of the treatment clearly visible.
Experimental design: Floraboost alongside an untreated control
To ensure a reliable comparison, the study used a treated plot and a control field.
The test consisted of:
- 3 repetitions;
- 840 m² treated with Floraboost;
- 872 m² of untreated control plot;
- organic farming in accordance with strict guidelines;
- SAP analyses for precise nutrient management.
Floraboost was applied six times via foliar spraying. The dosage was 3.5 liters per hectare, diluted in 1,000 liters of water.
The treatments took place every three weeks, from February through mid-June.
The result: 2.4 additional cucumbers per square meter
Over a 12-week harvest period, the treated crop showed a clear increase in yield.
Average production was:
- 43.87 cucumbers per square meter with Floraboost;
- 41.46 cucumbers per square meter without treatment.
That difference amounts to 2.4 additional cucumbers per square meter. On a per-hectare basis, this means approximately 24,000 additional cucumbers.
For an organic grower, that’s no small matter. Especially not in a market where uniformity, quality, and reliability of supply are key factors.
More Than Just Yield
Other differences were also observed during the trial. The Floraboost crop appeared stronger, more uniform, and more vigorous.
Key observations:
- fewer aphids;
- less visible plant stress;
- greater uniformity in size and quality;
- greener and more vibrant leaves;
- stronger crop growth during the growing season.
These effects are relevant because organic growers have fewer curative treatments at their disposal. A resilient crop is therefore not a luxury, but a prerequisite for stable production.
Why Floraboost Is Suitable for Organic Farming
Floraboost is a natural foliar application that supports the plant during active growth. The application is designed to enhance the crop’s vitality, nutrient uptake capacity, and resilience.
This is interesting for organic cucumber cultivation for three reasons.
1. Better utilization of growth potential
A cucumber plant must produce consistently for weeks on end. Even minor disruptions in nutrient uptake, stress, or leaf quality have a direct impact on the number of harvestable fruits.
Floraboost helps the crop maintain a better balance during that intensive production period.
2. Support without synthetic inputs
Organic growers are looking for solutions that fit within their cultivation system. Floraboost meets this need by focusing on providing natural support for the plant.
3. Greater uniformity in the harvest
Higher yields are valuable, but only if they are accompanied by high quality. In this trial, greater uniformity in size and quality was also observed. This can contribute to a higher market value for the harvest.
What organic growers can take away from this trial
Above all, the trial shows that biostimulants are most effective when used strategically—not as a stopgap measure once the crop is already under stress, but as part of a well-thought-out cultivation strategy.
Practical considerations:
- Start using the application on time;
- work at regular intervals;
- Combine this approach with effective nutrient monitoring;
- Evaluate not only yield, but also leaf color, stress, and uniformity;
- Always compare with an untreated control whenever possible.
It is precisely that combination of measuring, observing, and making targeted adjustments that makes all the difference.
Conclusion: small application, measurable difference
The cucumber trial in Antwerp shows that Floraboost can help organic growers improve their yields and crop vitality.
With a 5.8% increase in yield, 24,000 additional cucumbers per hectare, and visible benefits in plant health and uniformity, Floraboost offers significant added value for organic greenhouse horticulture.
