N2  - This study investigated the effects of vermicompost, biochar, and 
compost on the growth, yield, and fruit quality of Sweet pepper plants under 
greenhouse conditions during two consecutive seasons. The treatments were as 
follows: T1 (100% vermicompost), T2 (75% vermicompost + 25% biochar), 
T3 (50% vermicompost + 50% biochar), T4 (50% biochar + 50% compost), T5 
(75% compost + 25% biochar), and T6 (100% compost as control), Each 
treatment was arranged in three replicates. Results showed that vermicompost, 
either alone or integrated with biochar, significantly improved vegetative 
growth parameters (plant height, leaf area, and number of leaves). Moreover 
vermicompost treatments markedly increased fruit yield and improved fruit 
quality by elevating antioxidant compounds (total phenols, β-carotenoids, and 
ascorbic acid), while reducing nitrate accumulation in fruits. Although compost 
with biochar also produced positive effects, vermicompost-based treatments 
consistently outperformed all other treatments. These findings highlight 
the potential of vermicompost and biochar as sustainable and efficient organic 
amendments for sweet pepper production. By improving plant growth, boosting 
yield, and enriching fruit quality, these organic amendments provide 
 promising alternatives to synthetic fertilizers, thereby supporting sustainable, 
environmentally friendly, and resource-efficient agriculture.; أُجريت الدراسة لتقييم تأثير الفيرمي كمبوست والبيوشار والكمبوست، سواء منفردة أو في خلطات مختلفة، على نمو وإنتاجية وجودة الفلفل خلال موسمين بالصوب. أظهرت النتائج أن الفيرمي كمبوست منفردًا أو مع البيوشار كان الأكثر فاعلية، حيث حسّن النمو الخضري ورفع المحصول الكلي ومكوناته، وزاد محتوى الفينولات والبيتا-كاروتين وحمض الأسكوربيك والمواد الصلبة الذائبة مع خفض النترات لمستويات آمنة. كما أوضحت النتائج أن معاملات الفيرمي كمبوست تفوقت بوضوح على باقي المعاملات في جميع الصفات المدروسة. وتؤكد هذه النتائج أن الفيرمي كمبوست يمثل نهجًا زراعيًا مستدامًا ويدعم تحسين النمو والإنتاجية والجودة.
