Copy link Asparagus Trial with H2Flo
16
France 2016
16
Key Conclusions
When compared to the normal growers’ practice, using H2Flo increased asparagus yield by up to 16%, providing an extra €2,413 per ha of income, compared to normal grower practice.
Objective
To demonstrate that applying H2Flo will result in a reduction in irrigation volume while maintaining or increasing yield.
Trial Details
Trial station
France
Product
H2Flo
Assessments
Total yield, commercial yield, and caliber distribution
Treatments
Grower practice
- No usage of water conservation/surfactants.
- Two irrigation programs – 100% and 80% irrigation.
H2Flo
- The addition of H2Flo in the irrigation system was done once a week from 26/06/15 to 02/10/15.
- Dosage of H2Flo: 1.2 l/ha with first irrigation and 0.15 l/ha for weekly application in the period mentioned above.
All objects received the same amount of water from rainfall. Thus it seems that the normal grower practice (100% irrigation) received more water than the crop needs it, resulting in lowest performance as total yield.

Results
- By using H2Flo, the yield increased up to 16% compared to grower practice (100% irrigation) and reduced irrigation water by 20%.
- The total yield increased, especially in the 22+ caliber.
- H2Flo provided an extra income of €2,413 per ha, compared to normal grower practice (100% irrigation), achieved from extra yield. Reduced costs from less irrigation water, pump costs etc., are not included.
