Effect of Chitosan and Micro-Carbon-Based Phosphorus Fertilizer on Strawberry Growth and Productivity

High fertilization rates and pesticides are required for the intensive production of strawberries, which offer several therapeutic health benefits. Recently, chitosan (CHI), phosphorus fertilizer based on Micro Carbon TechnologyTM (MCT-P) were applied to encourage strawberry sustainable enhance phosphorus-use efficiency. Field trials conducted throughout 2020/2021 2021/2022, evaluate effectiveness MCT–P CHI in improving cv. Fortuna growth yield as well their quality. Foliar spraying MCT-P considerably improved plant (i.e., height, secondary crown number per plant, leaf area foliage fresh weight), photosynthetic pigment concentration (chlorophylla, chlorophyllb, carotenoids), its quality (early fruit yield, total average weight, firmness, dry matter %, soluble solid content, sugars (%), ascorbic acid, acidity, anthocyanin). Compared untreated plants, 1200 mgL−1 1000 mg/L supplementation was most effective all studied characteristics. The interaction between had a greater impact examined It is recommended spray with plus every two weeks, from 60 days after transplanting until weeks before end harvesting season best
