Tomato Trial with H2Flo 2014
25
Florida, USA 2014
25
Key Conclusions
Application of H2Flo to tomatoes generated a substantial $170/acre 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 randomized complete block trial with 4 replications
- Plots consisted of 40 feet long rows with 40 plants/plot.
- Tomatoes planted in single rows with one drip tape per plot.
Time | H2Flo | |
---|---|---|
weeks after transplanting | gal/acre | |
ICL treatment | 0 | .13 |

3 | .05 | |

7 | .05 | |
Total of 5 applications of H2FLo | .38 | |
Farm practice | No water conservation/surfactants. 3 irrigation programs (100%, 75% and 50% ETo) |
Volumetric Water Content: Soil volumetric water content (VWC) readings were taken at a depth of 6″ on bed centers, and 6″ 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)
Timing: Spring 2014
Location: Commercial field west central Florida, USA
Crop: Tomato, variety “Charger“, 12 weeks growing season
Soil type: Central Florida Sands
Measurements: Marketable yields (pounds/acre).

Results
- A positive $170/acre return on investment (ROI) in energy savings from 25% less irrigation.
- Yield maintained with 25% water saving, 100,000 ga/acre water saved.
- Plots treated with H2Flo at the 50% ETo level increased yield by more than the 100% ETo.
