Cultivating Resilience in Bell Peppers with Sili-Fert P

Horticulture Canada
One of the major persistent problems in both tomato and bell pepper cultivation is blossom end rot, often triggered by abiotic stress such as heat. Denva Greenhouses, located in the Kingsville-Leamington region, specialises in the cultivation of bell peppers on an area of 8.5 hectares. The main variety is Silverstone, known for its quality and yield potential, but also highly sensitive to blossom end rot. In recent years, Denva Greenhouses has worked closely with Roam Technology to further strengthen and improve resilience in their bell pepper crops.

THE CHALLENGE

Due to the Silverstone variety’s high susceptibility to blossom end rot and the impact of stress factors, Denva Greenhouses sought a solution to boost plant resilience and substantially reduce crop losses. The aim of this trial was to increase the vitality of the plants, sharply reduce blossom end rot losses, and at the same time increase the total harvest yield.

OUR SOLUTION

Roam Technology set up a trial at Denva Greenhouses, applying Sili-Fert P as a biostimulant. A dedicated section of the bell pepper greenhouse, covering 8,750 m² was treated every two weeks with Sili-Fert P, mixed into the standard spray schedule. An equal-sized control section was left untreated to objectively assess the impact of Sili-Fert P.

The section treated with Sili-Fert P achieved a total yield increase of 1.25%, while losses from crop wastage decreased by an impressive 47.17% compared to the control section.

This trial led to the full implementation of Sili-Fert P, which Denva Greenhouses continues to use to this day.

I think Sili-Fert P has great potential. During our trial, we noticed a significant reduction in waste on the treated side compared to the untreated side. One of the standout advantages is its compatibility. It mixes well with other products, allowing us to apply it without the need for a separate spray, which saves time and labor.

Conclusion

Applying Sili-Fert P resulted in clearly stronger and more vital plants with heightened resilience against external stress factors such as heat stress. Denva Greenhouses not only saw a higher net yield, but also a notable drop in losses due to blossom end rot.

  • Increased resilience to abiotic stress
  • Reduced losses caused by blossom end rot
  • Higher total yield
  • Stronger fruits, leaves and plants

Sili-Fert P

Sili-Fert P is a biostimulant based on silicon and enriched with micronutrients. It ensures plants develop their maximal natural resistance against abiotic stress.

Sili-Fert P can be applied either by foliar application or by dosage in irrigation water.
