The consequences of chicken manure and biochar either singly or together with three levels of NPK-recommended fertilizers on the growth, early and total yield, quality, and chemical components of Globe artichoke (Cynara scolymus L.) cv. Herous were investigated in a field trial performed for two consecutive seasons in 2022/2023 and 2023/2024. The experiment employed three replications in a split-plot design where, the main plots were filled with control, 10 tons of chicken manure per hectare, 5 tons of biochar, and a mixture of chicken manure and biochar (1:1) treatments. The sub-plots focused on NPK fertilizer levels, specifically 100%, 75%, and 50% of the recommended dose. When the chicken manure applied with 75% NPK of the recommended fertilizer dose, vegetative growth; plant height, number of leaves per plant, and chlorophyll content tended to increase. The fresh weight and diameter of the flower heads and receptacles were also noticeably higher with this treatment, yielding better over both seasons. Additionally, compared to the other organic fertilizers, the chicken dung mixed with 75% NPK of the recommended rate had resulted in greater levels of inulin, total phenolic and NPK in leaves. According to these findings, the addition of chicken manure produced the highest yield, quality, and chemical components of artichoke plants. This is probably because of raising the soil organic matter content, available NPK, and consequently the microorganisms, which have a positive impact on plant growth and yield components, beside it reduced the required chemical fertilizers for artichokes by 25%.
