| 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). | ||||
