| Abstract | ||
| Strawberry is one of the most Egyptian important vegetable crops for exports. So, a field experiment was conducted over two growing seasons (2021/2022 and 2022/2023) using a split-plot design to investigate the impact of two soil amendments as the main plots, including biochar at a rate of 5.0 m3 fed-1 and fulvic acid 10 kg fed-1. Also, the study aimed to investigate the benefits of foliar applications, in the sub-main plots involving organic carbon (1.0 cmL-1), seaweed extract (1.0 cmL-1), and potassium silicate (2.0 cmL-1), in addition to control. The study involved measuring some parameters, including foliage fresh and dry weights, no. of branches plant-1, leaf area (cm2 plant-1), chlorophyll content, as well as the percentage of NPK in the leaves. Additionally, the research included the evaluation of fruit characteristics, such as average fruit weight, fruit dry matter, No. of fruits plant, fruit firmness, total soluble solids, total sugars, vitamin C content and anthocyanin. Results showed that plants grown in soil treated with fulvic acid were the best than biochar, while the control plants had the least effective results. As for the foliar applications, with potassium silicate demonstrated the best performance, followed by seaweed then organic carbon as compared with control. The combinations of fulvic acid and potassium silicate appear particularly promising for achieving optimal results and enhance strawberry production for local and export market growth. | ||
