Two field experiments were carried out at special Farm at El Khatatba region Minofia Governorate , Egypt and in the Laboratory of Horticulture Department, Faculty of Agriculture at Moshtohor, Benha Univ., during 2014 and 2015 seasons to evaluate the effect of some fertilization treatments i.e. control (compost at 10 ton/fed.),100 % full chemical fertilizer dose, 75% chemical fertilizer (NPK) dose + compost at 10 ton/fed. + bio fertilizer (nitrobein + phosphorein) , 50% chemical fertilizer (NPK) dose + organic fertilizer (compost) + bio fertilizer (nitrobein + phosphorein) and 25% chemical fertilizer (NPK) dose + organic fertilizer (compost) + bio fertilizer(nitrobein + phosphorein) and some micro-nutrients i.e. Zn and B each at 100 ppm as well as their combinations on growth, total caffeic acid derivatives and total alkamides as well as chemical constituents of Echinacea purpurea plants. Results showed that different tested treatments of fertilization and micro-nutrients treatments as well as their combination led to significant increase of the studied growth parameters i.e. plant height, number of branches, fresh and dry weights of herb/plant, number of suckers/plant, number of flowering heads/plant, fresh and dry weights of flowering heads/plant as compared with control plants in both seasons. Additionally, the enhanced growth of Echinacea purpurea plants due to the different treatments was accompanied by pronounced increase in leaves N, P and K content of treated plants in both seasons. Furthermore, total caffeic acid derivatives and total alkamides were increased by all fertilization and micro-nutrients treatments as well as their combinations, especially the combined treatment between 75% chemical fertilizer dose + compost at 10 ton/fed. + bio fertilizer and Zn or B each at 100 ppm. Conclusively, from the obtained results, it is preferable to fertilize Echinacea purpurea plants with 75% chemical fertilizer (NPK) + 10 ton compost/fed. + bio fertilizer(nitrobein + phosphorein) in combination with some micro-nutrients (Zn or B each at 100 ppm) as foliar spray to enhance plant growth and chemical composition which led finally to a safe product of high quality suitable for exportation and safe on human health Keywords.Echinacea purpurea, chemical, organic and bio fertilization, micro-nutrients, growth , total caffeic acid derivatives and alkamides contents.
This experiment was carried out at the Shalateen station, Desert Research Center, Shalatin city-Red Sea Governorate, Egypt during the two successive seasons (2016/2017and 2017/2018) to study the effect of plants extracts (Garlic and Aloe vera) and amino acids on the vegetative growth, seed yield, oil yield and chemical constituents of Coriander plant. Results show that amino acids and/or extracts (garlic and/or aloe) stimulate and encourage of growth and yield characters of coriander plants. Also these treatments had a pronounced effect on essential oil (percentage and yield), as well as P and K%. The main constituents of essential oil under this study were linalool, p-cymene and limonene.
Background: Thalassemia major anemia patients require repeated blood transfusions, which improves their survival and quality of life, however it leads to iron overload and cellular damage. Serum ferritin and liver biopsy were used classically to measure iron overload and to monitor patient response to chelation therapy. Magnetic resonance imaging (MRI T2*) has proven to be a noninvasive, effective technique in detecting and quantifying myocardial and hepatic iron overload and in adjustment of iron chelation therapy.
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 (7 th 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 7 th Oct to 7 th Nov decreased both oil percentage and oil yield/plant. The highest values belonged to the early sowing date of 7 th 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 7 th November.A dose of (400kg per fed) ammonium sulphate (20.5%N) + super phosphorus, at the rate of 300 kg calcium super-phosphate (16 % P 2 O 5 ) per feddan +Potassium sulfate, at the rate of 100 kg potassium sulfate (48 % K 2 O) per feddan was recommnded.
