Flavonoid-based biostimulants and marketable yields: What potato farmers need to know

Recent research published in Frontiers in Sustainable Food Systems provides compelling evidence that Maxstim’s flavonoid-based biostimulant Agriculture+ can increase not only total yield but more importantly, marketable yield, delivering significant financial returns to growers.

Science-backed results from lab to field

Key study findings:

• 33% increase in tuber weight across three potato varieties in container trials
• 10.4% increase in tuber number per plant
• Significant shift toward larger tubers in the marketable size range (45–85 mm)
• 5.2% average increase in total yield across six commercial UK field trials
• Marketable yield improvements consistent across all trial sites
• £700 average increase in profit per hectare

Application across varieties and conditions

The product was tested on multiple potato varieties (Maris Piper, Navan and Lady Rosetta) in both controlled container experiments and field environments.
It showed:

• Consistent improvements regardless of seed type (chitted vs unchitted)
• Positive effects under standard commercial farming practices
• No adverse impact on tuber quality characteristics (e.g., dry matter, specific gravity, starch content)
