| The development of environmentally friendly strategies to support crop productivity is increasingly vital in modern horticulture. This study assessed the impact of a novel biostimulant composed of effective microorganisms (EM), Spirulina platensis, and earthworm humus on the physiological performance, defense response, and yield of strawberry (Fragaria × ananassa cv. Albion) grown in pots. The experiment was carried out under semi-controlled conditions at CREA in Pescia, Italy, with biostimulant applications delivered via fertigation every two weeks for a duration of two months. Various plant growth indicators, antioxidant enzyme activities, and fruit production metrics were recorded. Treated plants exhibited significant increases in leaf expansion, chlorophyll content, and flowering compared to untreated controls. Enzymatic assays revealed elevated activity levels of phenylalanine ammonia-lyase (PAL), peroxidase (POD), and superoxide dismutase (SOD), alongside a notable increase in total phenolic content, indicating enhanced activation of natural defense mechanisms. Fruit yield improved by approximately 25% without compromising sweetness or fruit size. Although °Brix and individual fruit weight remained unchanged, the uniformity and marketability of fruits improved. These findings suggest that the synergy between EM, S. platensis, and vermicompost effectively supports both metabolic function and productivity in strawberry cultivation. The use of this biostimulant formulation may offer a practical and sustainable tool for improving horticultural output while minimizing dependence on chemical inputs. Further trials in field conditions are recommended to validate these results across diverse environments and production systems. | ||
