ABSTRACT
The present study was carried out at El-Sheikh Zowaid Research Station , Desert Research Center, North Sinai Governorate, during the two successive seasons of 2008/2009 and 2009/2010. The objective of this work was to study the effect of sowing date, applying of chemical, bio and organic fertilizers on the vegetative growth and essential oil productivity of Foeniculum vulgare var. panmorium Mill .( Indian fennel type). The highest values of vegetative growth measurements were obtained with treatment F5 (100% recommended dose+compost (CM) + biofertilizer) which produced the tallest plants, the heaviest fresh and dry weights of herb/plant as compared to other fertilization treatments. The early sowing date (7th October) proved to be the most effective one for producing the best vegetative growth in comparison with the other sowing dates. In addition, the highest number of umbels /plant, fruit yield/ plant (g) and per feddan (ton) and weight of 1000 fruits (g) were recorded by using the treatment F5 (100% recommended dose+compost (CM) + biofertilizer). The highest oil percentage was due to fertilization treatment F4 (biofertilizer +5 ton compost/fed). Whereas, the highest oil yield/plant was obtained from F5 treatment (100%recommended dose) + compost (CM) + biofertilizer. Delaying planting date from 7th Oct to 7th Nov decreased both oil percentage and oil yield/plant. The highest values belonged to the early sowing date of 7th October. Moreover, the highest leaf N, P and P contents were gained with the treatment of F5 (100%recommended dose) + compost (CM) + biofertilizer in both seasons. The main detected component was trans-anethole which is considered an important constituent, followed descendingly by fenchone then estragole. There are other major components including limonene and ,α-pinene that were found in the tested oil. Delaying sowing date decreased anethol content in the volatile oil. Fenchone percentage in the fennel volatile oil was generally increased with delaying sowing date, and also methyl-chavicol (estragole) was higher in delayed dates, while limonene and ρ-cymene recorded the least value with the late sowing date of 7th November.
A dose of (400kg per fed) ammonium sulphate (20.5%N) + super phosphorus, at the rate of 300 kg calcium super-phosphate (16 % P2O5) per feddan +Potassium sulfate, at the rate of 100 kg potassium sulfate (48 % K2O) per feddan was recommnded.
Key words: anethol, estragole, fertilization, foeniculum, Indian fennel, oil constituents, sowing date.
