Organic strawberry farming in Morocco faces major challenges related to pest and fungal disease management. This study assessed the agronomic and qualitative performance of two short-day strawberry varieties, Palmeritas and Victory, under organic treatments in the Loukkos region during the 2023–2024 growing season. A total of 384 plants (192 per variety) were selected using a stratified random sampling method. Treatments included biostimulants and GC-Mite, a biopesticide composed of clove, garlic, and cottonseed oils. Palmeritas recorded a higher yield (1.72 t/ha vs. 1.58 t/ha for Victory) and superior sugar content (8.30°Brix vs. 7.89°Brix), while both varieties showed significant reductions in aphid and fungal disease incidence. Sensory analysis highlighted differences in fruit texture and taste. These findings underscore the potential of tailored organic strategies to enhance strawberry production by improving yield and fruit quality while reducing pest and disease pressure. Multi-season and multi-location trials are needed to confirm these observations and support the large-scale adoption of sustainable practices.

摘要

Organic strawberry farming in Morocco faces major challenges related to pest and fungal disease management. This study assessed the agronomic and qualitative performance of two short-day strawberry varieties, Palmeritas and Victory, under organic treatments in the Loukkos region during the 2023–2024 growing season. A total of 384 plants (192 per variety) were selected using a stratified random sampling method. Treatments included biostimulants and GC-Mite, a biopesticide composed of clove, garlic, and cottonseed oils. Palmeritas recorded a higher yield (1.72 t/ha vs. 1.58 t/ha for Victory) and superior sugar content (8.30°Brix vs. 7.89°Brix), while both varieties showed significant reductions in aphid and fungal disease incidence. Sensory analysis highlighted differences in fruit texture and taste. These findings underscore the potential of tailored organic strategies to enhance strawberry production by improving yield and fruit quality while reducing pest and disease pressure. Multi-season and multi-location trials are needed to confirm these observations and support the large-scale adoption of sustainable practices.
