Significant onion data from 23 commercial field trials
Over the past four years, Maxstim has conducted 23 rigorous commercial onion trials across the UK to help growers achieve higher yields and profitability. Testing red varieties such as Red Baron and Red Tide and brown varieties including Donna and Nation, our trials provide clear evidence of the power of our innovative bioflavonoid and complex biostimulant technology.

Key results include:
- 5.73% average yield increase: Marketable yields showed consistent growth across trials.
- Higher margins: Growers saw additional margins of £350–£600/ha. Equivalent to $263–$444/acre.
- Reliable yield increase of marketable grades 50mm – 80mm+.
