Kohlrabi Trial with Solinure Polymarine in Israel

Solinure Polymarine is a chloride-free fertigation fertilizer with trace elements, Advanced-P, and seaweed extract, boosting crop growth, stress tolerance, and providing both quick and sustained nutrition.

2023

Key Conclusions

  • The Solinure Polymarine and Solinure Polymarine + BIOZ Diamond treatments delivered the best yield parameters for kohlrabi, compared to the commercial practice, with no statistical difference between the two Polymarine treatments.
  • The contribution of BIOZ Diamond bio-stimulant to the yield of the Farmers Practice + BIOZ Diamond (FP+M) treatment is reflected in the application to the soil in subsequent growing season.
  • When comparing the kohlrabi yield as a percentage of the overall biomass, the Solinure Polymarine treatment was significantly higher than all other treatments.

Objective

To examine the effects of Solinure Polymarine and BIOZ Diamond on plant growth and development.

Assessments

Total Biomass, Leaf Yield, Kohlrabi Yield

Treatments

  • Solinure Polymarine (P)
  • Solinure Polymarine (10-6-37+TE+SW+AN) + BIOZ Diamond (PM)
  • Farmers Practice (Arava 12-2.5-5) (FP)
  • Farmers Practice + BIOZ Diamond (FP+M)
  • Control (No fertilizer) (C)

The NPK application rate was identical in all treatments apart from the control (no fertilizer).

Treatments

  • Solinure Polymarine (P)
  • Solinure Polymarine (10-6-37+TE+SW+AN) + BIOZ Diamond (PM)
  • Farmers Practice (Arava 12-2.5-5) (FP)
  • Farmers Practice + BIOZ Diamond (FP+M)
  • Control (No fertilizer) (C)

The NPK application rate was identical in all treatments apart from the control (no fertilizer).

Results

 

  • Treatments P and PM resulted in the highest total biomass, significantly higher than other treatments, but not statistically different from each other.
  • Leaf yield was highest in treatments P and PM, while not statistically different from each
  • The kohlrabi yields from treatments P and PM were significantly higher than the other treatments but were not statistically different from each. Treatment C (No fertilizer) was significantly the lowest for all yield parameters.
