Key Conclusions
Application of H2Flo to tomatoes generated a substantial €390/ha return on investment (ROI) in energy savings from 25% less irrigation, while maintaining, or even increasing, yield.
Objective
To demonstrate that applying H2Flo wetting agent results in a reduction in irrigation volume while maintaining, or increasing, yield.

Assessments
Yield, water conservation, and return on investment (ROI)
Treatments
- This was a randomised complete block trial with 4 replications
- Plots consisted of 12 meter long rows with 40 plants/plot.
- Tomatoes planted in single rows with one drip tape per plot.
| Time | H2Flo | |
|---|---|---|
| weeks after transplanting | L/ha | |
| ICL treatment | 0 | 1.2 |
| 1 | 0.6 | |
| 3 | 0.6 | |
| 5 | 0.6 | |
| 7 | 0.6 | |
| Total of 5 applications of H2FLo | 3.6 | |
| Farm practice | No water conservation/surfactants. 3 irrigation programs (100%, 75% and 50% ETo) |
|
Soil volumetric water content (VWC) readings were taken at a depth of 15 cm on bed centres, and 15 cm from the west edge (50 observations during the season).
- Plant height (3 weeks after transplanting [WAT])
- Foliar dry biomass/plant (3 and 15 WAT; 5 plants/plot)
- Marketable yields (10 and 12 WAT)

Results
- A positive €390/ha return on investment (ROI) in energy savings from 25% less irrigation.
- Yield maintained with 25% water saving, 1M L/ha water saved.
- Plots treated with H2Flo at the 50% ETo level increased yield by more than the 100% ETo.
