Abstract
Among the bio-tools that contribute to making the strawberry production system more sustainable are arbuscular mycorrhizal fungi (AMF), which can be used as biofertilizers. Thus, five doses of phosphorus (P) applied to plants with AMF and a control (100% P, no AMF) were analyzed in order to differentiate the horticultural potential of the ‘Camarosa’ cultivar. We used an on-farm inoculant made up of six fungal species. The univariate and multivariate analyses showed that the addition of AMF to the growing substrate made it possible to reduce the P supply in the nutrient solution by 75% without compromising the fruit yield. In addition, this combination improved the phytochemical quality of strawberries, the plant’s root system morphology, and the accumulation of nutrients in plant organs (roots, crowns, aerial part and fruits). We conclude that the use of a multi-species on-farm inoculant based on AMF associated with a reduction in the P supply in the nutrient solution modifies the horticultural potential of the ‘Camarosa’ cultivar. We confirmed the action of a native AMF community as a biofertilizer.
