Background: Two cultivars (Balady and Dukat) of dill plants were grown in the Experimental Farm Station of Agriculture Faculty, Cairo University, during two seasons of 2014/2015 and 2015/2016. This investigation aims to determine the response of two dill cultivars to seven fertilizer treatments, i.e., control, 100% mineral fertilizer, 100% biofertilizer, 100% organic fertilizer, 50% organic fertilizer, 100% organic fertilizer with biofertilizer, and 50% organic fertilizer with biofertilizer. Data on plant height, leaf number, and some chemical composition such as antioxidant and nitrate accumulation were recorded in the vegetative growth stage. Results: The results demonstrated that dill cv. Dukat gave the highest plants (cm), maximum leaf number per plant, pigment content (mg/g), total carbohydrates (%), nitrogen, and phosphorus percentages in the vegetative growth stage. Meanwhile, dill cv. Balady recorded the maximum potassium percentage and low content of nitrate accumulation (mg/kg) in the vegetative growth stage. Both dill cultivars contained antioxidants without significant differences between them. The best fertilization treatments were 100% organic fertilization with biofertilizer and 100% chemical fertilizer for plant height (cm), leaf number per plant, pigment content, antioxidant percentage, total carbohydrate percentage, and N and P percentages of two dill genotypes. On the other hand, 50% organic fertilization with biofertilizers was recorded as the best treatment for nitrate accumulation and K percentage with two dill cultivars. Conclusion: These results prove that chemical fertilizers could be completely replaced by organic sources supplemented by NPK Symbion without any negative effect on dill vegetative growth and or nutrient contents.
