Abstract

Field trials were conducted during 2011and 2012 seasons in the
private farm of Kom Ombo, Aswan Governorate, Egypt to study the
effect of various rates of chemical N and foliar spray) treatments and
the combinations between them on growth, yield and chemical
constituents of damsissa (Ambrosia maritima, L.) plants. Nitrogen
(ammonium sulphate) with three levels (0,100 and 200 kg/fed) was
used and Nutri- Leaf (N20-P20-K20)+Me treatments (0, Lf 100 and Lf
200 ppm.) added as foliar spray three days after irrigation till run-off, 3
times during preparing the experiment field. The data shows that
treading plants with nitrogen and Nutri-Leaf significantly increased the
vegetative growth compared with control. Likewise, all fertilization
treatments greatly raised the percentage of N, P and K in the herb, as
reached by the increased fertilization maximum. As for fresh and dry
herb, the data showed that using nitrogen and 200 kg and Nutri-Leaf at
200 ppm. can be used to significantly increase these parameters and
active substances (ambrossin, damssin and sesquterpene).
