Abstract

The present study was carried out in field during the growing
seasons 2004/2005 and 2005/2006 to investigate the effect of
macronutrients at the rates of N (75 and 100 kg /fed). P2O5 (32 and 50
kg./fed.) and K2O (24 and 36 kg./fed.) and the mixture of micronutrients
(Fe, Mn and Zn at the rate of 2%) on growth, yield and chemical
constituents of chamomile plants. The data obtained from the study
show that the treated plants with the high rates of macronutrients (NPK)
either alone or in combination with each others increased all the studied
characters such as growth parameters (plant height, number of branches,
fresh and dry weights of plant), yield (number of inflorescences/plant,
fresh and dry weights of inflorescences/plant and dry yield /fed.) and
some chemical constituents such as (N, P, K, Fe, Mn, Zn, pigments and
total carbohydrates). Also yield of oil (oil percentage, oil yield/ plant
and fedann) Generally, the maximum increase of the previous characters
was obtained by the treatment which contain the high rate of NPK
fertilizers (100, 50 and 36 kg/fed., respectively) either alone or in
combination with spraying chamomile plants with micronutrients (Fe,
Zn and Mn) at the concentration of 2%.
Therefore, under newly reclaimed soil conditions prefer fertilization
chamomile plants with (100, 50 and 36 kg/fed. from NPK fertilizers,
respectively in combination with micronutrients (Fe, Zn and Mn) at the
concentration 2% to obtain the good yield from the plants.
