Abstract

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