Kaumera confirmed as effective biostimulant for bell peppers under drought stress

Two recent trials at the renowned research institute Landlab (Italy) confirm Kaumera’s potential as a biostimulant in the cultivation of bell pepper (Capsicum annuum). The studies assessed Kaumera's performance under both optimal and water-stressed growing conditions—scenarios that are increasingly relevant due to climate change.

When applied as a foliar spray under drought stress, Kaumera delivered impressive results:

• +16.4% increase in fruit weight
• +11.5% more fruits per plant

Even under optimal conditions, positive trends were observed in fruit weight and total biomass. Treated plants also showed higher photosynthetic activity and elevated Brix levels, indicating sweeter fruit. Notably, plants under stress displayed reduced root growth, suggesting more efficient energy allocation toward fruit development.

The trials explored two application methods: foliar spray and substrate incorporation. For Dutch greenhouse horticulture, the foliar spray method appears most relevant, while substrate application may hold potential in international markets with alternative growing systems.

Kaumera continues to prove itself as a valuable biostimulant for stress-sensitive crops like bell pepper. Similar effects were previously observed in maize—a dedicated update on those findings will follow soon.

The trials were conducted by Landlab, with materials provided by the Kaumera cooperative.
