A field experiment was carried out during the two successive seasons of 2012/2013 and 2013/2014 in North Sinai Governorate, Egypt to evaluate the seed productivity and quality of some Russian dill varieties by using organic farming practices. The experiment was conducted in split plot design. The main plots included foliar spray of various concentrations of blue-green algae extract of Spirulina platensis (0, 0.5, 1 and 1.5 liter extract/200 liter water/feddan). The sub-plots included sowing of five different dill varieties (local, Superdukat OE, Max, Salute Bush "Fireworks" and Aurora). The interaction results indicated that cultivation of Aurora variety combined with foliar spray of 1.5 liter of blue-green algae extract produced significantly maximum seed yield per plant and per feddan, volatile oil yield per plant and per feddan in addition to obtaining the highest d-limonene concentration as an important aroma impact component in seed volatile oil over control treatment (cultivation of local type without foliar spray of algae extract) which recorded the lowest parameters.
