The objective of this work was to optimize a soilless growing system for producing tray strawberry plants in sawdust-based (PS25) and aged bark (AB) substrates under greenhouse conditions. More precisely, we aimed to test the potential of plugs to obtain consistent early strawberry yields in AB and PS25 growing media. Planting tray plants resulted in earlier fruiting, increased early and seasonal yields as well as increased average fruit size, in comparison with bare root plants. Interestingly, our results showed that the intense nutrient immobilization in PS25 had no impact of seedlings performance for tray plants, in contrast with bare-root plants. The present study suggests that plug plants can be an interesting economic alternative to bare-root plants for strawberry tray plants production under soilless culture in Northern America.
