“…The results recorded in the two seasons (Table 3) show that, in general, the number of flower stalks /plants was significantly increased by most of the tested fertilization treatments. The favourable effect of the different fertilization treatments on flower production is in agreement with the findings of Correa-Junior et al (1999) on Chamomilla recutita plants, and Gouda (2002) on Tagetes erecta.…”

, during the two successive seasons of 2000 and 2001, with the aim of investigating the effect of chemical, organic and bio-fertilization treatments on the growth and chemical composition of Joseph's coat (Amaranthus tricolor L.) plants. The treatments included fertilization with PK (P at 6 g calcium superphosphate, and K at 3 g potassium sulphate / 25-cm clay pot), combined with: (1) N fertilization at the rates of 6 or 12 g ammonium sulphate /pot (N 1 and N 2 , respectively), (2) Bio-fertilization (Bio), (3) Bio. + half the previous N fertilization rates (½ N 1 or N 1), (4) Cattle manure (CM) at the rate of 710 cm 3 /pot (equivalent to 40 m 3 /feddan), or (5) Bio + CM at 355 cm 3 /pot (equivalent to 20 m 3 /feddan). Control plants received PK fertilization only. The bio-fertilizer was applied to the soil as a liquid inoculum containing Azospirillum brasilense, Klebsiella pneumonia and Pseudomonas putida. Most of the fertilization treatments increased the different vegetative growth and flowering characteristics. Among the different treatments, combining Bio with CM (i.e. PK + Bio + ½ CM) was the most effective one, giving the highest values for plant height, stem diameter, leaf area, number of flower stalks/plant, fresh and dry weights of leaves and stems/plant, as well as the the highest contents of chlorophyll "a", total chlorophylls (a+b), carotenoids and anthocyanin in the leaves. Also, this treatment (PK + Bio + ½ CM) gave the highest content of total carbohydrates in the leaves, stems, flowers and roots (in most cases). On the other hand, PK+N 2 gave the highest numbers of branches /plant, and the longest flowering stalks, while the highest number of leaves was found on plants fertilized using PK + N 2 or PK + ½ CM + bio-fertilization. PK + N 1 + Bio gave the highest roots fresh weight in both seasons. Plants fertilized with PK + N 2 had the highest N content in the leaves (in both seasons), stems and flowers (in the first season), as well as the highest P content in the roots (in both seasons) and stems (in the second season). It was concluded that, for best vegetative growth and flowering of Amaranthus tricolor, L. the plants should be fertilized using the previously described mixture of PK, bio-fertilization and half of the full dose of organic (cattle) manure.

The Egyptian chamomile has a good reputation in the export markets due to hand pick of the flower heads and application of organic farming system. However, in the last decade exports of chamomile faced some problems due to inconsistency with the required oil quality. Accordingly, a long term program was initiated for quality improvement of chamomile grown in Egypt. This approach depended on a selection program within the local variety as well as introduction of new sources from other countries to diversify the available product of chamomile in Egypt.This investigation was carried out during two successive seasons to evaluate the growth, productivity and oil quality of four cultivars of chamomile grown in three different locations in Egypt. The used cultivars were; Local (the type locally grown for several decades), Local Improved (resulted from selection program for 6 years), Bode Gold (introduced from Germany) and Syrian (introduced from Syria).The obtained result revealed that the Bode Gold type was superior regarding its productivity per unit area in comparison with the other types of chamomile. Such productivity is the net accumulation of the growth traits; flower head diameter, fresh and dry weight of flowers per plant. The Local improved type came in the second rank. A positive correlation could be observed between the yield of flower heads and the flower head diameter.In most cases cultivation of the different types in different locations did not affect the ranking of these types meaning the stability of these types under different growth conditions. The obtained results revealed that the oil composition of chamomile types under investigation is stable and characteristic for each type even when cultivated in the different locations. The selection programs in the local variety positively affected the growth traits, flower size and yield of chamomile, and to a lesser extend the oil content. There was a noticeable improve in the oil content of the improved cultivar to reach 1.06 and 0.94 % in the two seasons, respectively. It also led to an increment in the total content of the four major constituents to constitute 83.96 % of the oil compared with 72.21% in the original one, as well as remarkable increase in the chamazulene Journal of Essential Oil Bearing Plants percentage to reach 44.31 % compared with 38.34 % in the original local variety.As a result of the present study, several types of chamomile are available for chamomile producers to fulfill the variable specifications for export. The Syrian type of chamomile adapted under the local conditions is a potent one for chamomile oil production.
