The Case
Commercial pak choi production contains multiple compounding yield losses that most operators manage separately — or not at all. Saturn's Hydronomy crop science team ran three parallel studies at the Offenham R&D facility to systematically quantify the performance levers: variety genetics, root-zone nutrition treatment, and propagation method. Benchmarked against Goku F1, the UK commercial standard.
The Integration Highlight
Root-zone nutrition treatments were found to affect plant architecture — not just mass. Boost treatments produced tighter, more upright heads with fewer protruding leaves, improving yield and structural resilience simultaneously. Silicon supplementation measurably improved snap resistance. No single lever achieves the combined result — variety, nutrition, and propagation must be optimised together. That is Saturn's methodology.
Key Achievements
- ● Variety selection: 3 of 11 varieties achieved more yield AND less packaging trim than Goku F1 — with You Qing choi delivering compact, snap-resistant heads that outperform on both dimensions. Head architecture and yield must be assessed together; raw headweight alone does not predict commercial performance.
- ● Root-zone nutrition: boost treatments delivered bigger yield gains than varietal switching alone, and improved plant architecture simultaneously. You Qing choi + Root-zone Conditioner reached 250g trimmed weight — +97% above the Goku F1 untreated baseline. Silicon supplementation measurably improved snap resistance across varieties.
- ● Propagation: Ellepot biodegradable plugs produced visibly more vigorous root systems than Rockwool, with an establishment advantage that compounds through the entire crop cycle. Propagation method is a yield driver — not a logistics choice.
