We measured SPME (Solid phase microextraction) and GC-MS (gas chromatograph-mass spectrometer) we examined the effects of the different fertilization settings for the herb's main active ingredients of essential oil's percentage. Based on the results, it was concluded, the essential oil agents' percentage breakdowns significantly depending on the cropping technologies. Besides that it is possible, based on Pearson's correlation test the marigold essential oil agents relationship can also be a major factor.application/pdfherbnutrient supplymarigoldessential oilactive agentfolyóiratcikkOpen Accesshttps://doi.org/10.34101/actaagrar/70/1818Acta Agraria Debreceniensis70Acta agrar.
