The paper studied the impact of integrated plant nutrients management strategy (IPNM) on the agricultural return during current Syrian crisis through the application of camel manure and chemical fertilizers on the black cumin quantitatively and qualitatively. The fertilization treatments were denoted as T₂ [N₁₂₀-P₃₀-K₃₀], T₃ [N₁₂₀-P₃₀-K₃₀], T₄ [5 t. ha_-1 camel manure], and T₅ (½ [T₃ + T₄]), respectively. The no-fertilizer treatment (T₁) was considered as control. Soil fertility, irrigation water use efficiency (IWUE), and oil content were considered. Results have showed that organic manure(camel dung)decreased soil pH and OC/ON ratio and increased the availability of nutrients in the soil. What led the black cumin to respond by significantly increasing the following productive parameters: plant height, roots depth, number of primary and secondary branches,..etc. The treatment T₅ recorded the highest IWUE values (5.2 and 6.2 kg.ha_-1.mm_-1) and the best oil content (33.3% and 34.2%) in the two seasons, respectively. Furthermore, the applied IPNM strategy had remarkably increased fertilization efficiency and economical feasibility (profit/ total costs) in the order of T₅>T₄>T₃>T₂ compared to T₁.
