Role of Vermicompost and algae Extract in Improving Growth and Fruit Quality of Mango (Keitt)

This research, spanning the 2021 and 2022 seasons, aimed to explore the impact of vermicomposting on the growth and productivity of Mango trees (cv. Keitt) cultivated in sandy soil at Ahmed Orabi Agricultural region, El-Obour City, Cairo Governorate, Egypt. The selected trees underwent various treatments, including water (control), vermicomposting at 1 or 2 Kg/tree, Spirulina platensis algae extract at (5 or 10ml/l), and their combinations. Optimal results in terms of leaf fresh and dry weight, leaf area, and chlorophyll content were observed with the treatment of 2kg vermicompost + 10ml/l algae extract. Furthermore, the addition of vermicompost along with algae extract improved the leaf status of N, P, K, and Ca. Application of both vermicompost and algae extract, whether individually or in combination, demonstrated positive effects on the physicochemical quality of the fruit. The findings suggest that the simultaneous use of vermicompost and algae extract holds promise as a supplementary material for enhancing the growth, productivity, and fruit quality of Mango trees.
