In brief

A later-stage programme that separates root-zone system suitability, nutrient strength, N×K interaction, fruit chemistry and sensory quality.

Why strawberry is phase two

\n

Strawberry requires a longer cycle, flowering and fruit set, stronger root-zone oxygen control, pollination management and post-harvest standardisation. A 2025 system comparison found the tested substrate system outperformed the tested water-culture systems, so the FlavoRotor root zone must be validated before flavour treatment claims.

\n

Two different literature anchors

reported the two-thirds treatment as the best compromise for the tested Kuemsil crop, but that result is not universal.

Programme sequence

\n
  1. Validate survival, flowering, fruit set and root-zone oxygen under one conservative recipe.
  2. Compare root support/medium configurations before nutrient-strength optimisation.
  3. Test nutrient strength in one named cultivar.
  4. Run an N×K factorial only after stable baseline production.
  5. Measure yield, °Brix, titratable acidity, firmness, volatiles and blinded sensory profile together.
\n

supports the N×K interaction design; supports combining volatile, quality and sensory analysis across cultivars.
