abstract
The present work was conducted on Dutch fennel plant strains during the two successive seasons of 2014/2015 and 2015/2016 in El-Maghara region, North Sinai Governorate, Egypt to detect the effect of sowing dates, organic fertilization, foliar spray of Spirulina platensis algae extract and the interaction among treatments on fruits and essential oil productivity. The experiment was planned in split split plot design. The interaction results showed that the significantly maximum increments in growth, fruits and oil yields were obtained when plants were sown in the early sowing date (15^th of October) and received the higher level of compost manure (20 m³/fed.) combined with foliar spray of Spirulina platensis extract. The major chemical constituents of extracted essential oils were trans-anethole, estragole, l-fenchone and d-limonene.
