Abstract Two field experiments were conducted at Ismailia and El Fayoum sandy soils to evaluate the impact of organic and inorganic fertilization on Nigella sativa yield and its oil quality. The used organic manures are sewag sludge; chicken, compost and biogas with and without ammonium nitrate and superphosphate applications. Soil water constants, bnlk density and available macro and micronutrients content were significantly improved by applying these organic manures, depending on their organic and elemental content. Moreover, Nigella sativa growth parameters, straw, and seed )’ield were significantly increased by applying NP combined with the organic manures. This trend was affected by using the relatively saline irrigation water in Ei-Fayoum location compared with the fresh one in Ismailia. The fixed and volatile oil content and their constituents were also affected by the applied organic and inorganic manures, however, using saline irrigation water decreased the volatile oil content of seeds and increased the fatty acid content in plants grown in EL.-Fayoum area. |
