<b>Background and Objective:</b> Biological fertilization in the development of agriculture became one new strategy in the increased production of field crops to decrease the costs of production input and environmental pollution. This study focused on the influence of biochar fertilization on the productivity of faba bean varieties under sandy soils. <b>Materials and Methods:</b> Appreciation of the yield and its components, in addition to measurement of grain protein content as well as carbohydrates (%) of faba bean. <b>Results:</b> The data obtained indicated that the biochar amendment affects plant production at different rates, where the best yield obtained is 90 kg fed<sup>1</sup>. The grain yield increase is significant for the variety's types where, Mariout-2, followed by Nubaria-3 followed by Giza-716 for the addition of 90 kg fed<sup>1</sup> of biochar as referenced by the non-conditioning treatment. Likewise, the protein content was highest in the Mariout-2 variety, followed by Nubaria-3 variety and Giza-716 variety for the addition. This improvement may be regarded to the impact of biochar on the physic-chemical characteristics for the soils, in addition to the biological characteristics. Furthermore, the biochar itself add nutrient to the soil after decomposition. The best improvement happens by the long-term cropping for a long period could be reached up to years. <b>Conclusion:</b> The conclusion that plant growth was better at a high rate (90 kg fed<sup>1</sup>) but the economy of this rate may be questioned, under the condition of the study. However, the validation for different soils may vary with different rates, which needs more research. Also, it is recommended to use Mariout-2 cultivars for their high production under these conditions.
农业生物施肥成为提高大田作物生产力、降低生产成本投入和环境污染的新策略之一。本研究重点探讨了生物炭施肥对沙质土壤中不同蚕豆品种生产力的影响。材料与方法：评估产量及其构成，以及蚕豆的籽粒蛋白含量和碳水化合物（%）。结果：研究结果表明，生物炭施肥对植物生产的影响程度不同，其中获得的最佳产量为 90kg/ fed<sup>1</sup>。对于添加 90kg/ fed<sup>1</sup>生物炭的品种，产量增加显著，Mariout-2 品种次之，Nubaria-3 品种次之，Giza-716 品种次之，而非条件处理。同样，Mariout-2 品种的蛋白质含量最高，其次是 Nubaria-3 品种和 Giza-716 品种。这种改善可能归因于生物炭对土壤物理化学特性以及生物特性的影响。此外，生物炭本身在分解后也会向土壤中添加养分。通过长期轮作，可以达到最佳的改善效果，持续时间可达数年。结论：在研究条件下，高添加率（90kg/ fed<sup>1</sup>）下植物生长更好，但该添加率的经济性可能值得质疑。然而，不同土壤的验证结果可能因添加率的不同而有所差异，这需要进一步研究。此外，建议在这些条件下使用 Mariout-2 品种，因为它们的产量较高。
