During our research we investigated the marigold's (Calendula officinalis L.) nutrient requirements with different fertilization setting in small-plot trial. 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.

During our research we investigated the marigold's (Calendula officinalis L.) nutrient requirements with different fertilization treatments in small-plot trial. We measured the harvested marigold's drug's raw and dry weight on a weekly basis from July 6th until August 17th. We were using SPME (Solid phase microextraction) and GC-MS (gas chromatograph-mass spectrometer) to examined the effects of the different fertilization settings for the herb's main active ingredients of essential oil's percentage. It was concluded, based on the results, the N30P40K60 fertilization setting is ideal in terms of the quantity of the marigold drug. Both the raw and the dry weights' measurements of the case, this fertilization setting have the most important effect on the herb's yield. The analysis of variance didn't show significant differences between the plots with different fertilization settings. We discovered relationship between the drying loss and the increasing quantities of nutrients. We think it may be possible the Alpha-thujon's and Alpha-cadinol's production and the drying loss's data are connected, which appear to confirm the N15P20K30 treatment's data.

During our research we investigated the Mediterranean summer savory’s (Satureja hortensis L.) nutrient requirement with different fertilization settings in a small plot trial. We measured the medicinal plant’s raw and dry drug mass, and the presence of the main essential oil active agents under the different fertilization settings using SPME (Solid phase microextraction) and GC-MS (Gas Chromatograph mass spectrometer). From the drug’s raw and dry mass perspective, based on the obtained results, in our opinion, the N30P40K60 nutrient requirements were ideal in 2015, while the N60P80K120 nutrient requirement showed the best values in 2016. A significant relationship is assumed between the different fertilization settings and the essential oil active agents’ distribution. During the analysis of data, we compared three of the savory’s essential oil active agents’ percentage of presence in the nutrient requirement samples.

The Impact

Introduction. Marigold (Calendula officinalis L.) is an annual plants belongs to Asteraceae family. The species is widespread in the world and have a long tradition of medicinal use with multidirectional action. Aim. The field experiments were carried out to assess the impact of genetic (cultivar) and environmental factors on yielding variability and biosynthesis of essential oil in conditions of conventional cultivation of marigold after using different methods of plantation weeding. Material and methods. The research material were two cultivars of marigold such as Orange King and Indian Prince. The following activity were tested: 1) spraying of Fusilade Forte 150 EC (1 l • ha-1), 2) spraying Fusilade Forte 150 EC (1 l • ha-1) + manual weeding, 3) manual weeding, 4) no weeding – control. The scope of the research included assessment of marigold yield (inflorescence) and determination of the essential oil contents in dry mass of raw material. Results. Regardless of the cultivar, a non-chemical methods (mechanical weeding in interrows and manual in rows) gave the highest efficiency of weed control. Similar results observed after using chemical weeding with manual weeding. In these cases the yields were at least 2.5 times higher than obtained from the control. The total yield of dry mass of inflorescence for the above methods was 6.35 and 5.53 q • ha-1 for Orange King cultivars, slightly lower result obtained for cultivar of Indian Prince (4.81 and 4.12 q • ha-1). It was also shown that the content of essential oil in the raw material ranged from 0.25 to 0.37% and was independent from the cultivar. Conclusions. The Orange King cultivar of marigold yielded better than Indian Prince in analogous methods of plantation weeding. The highest effectiveness of weed plantation was found using a non-chemical method (mechanical weeding in interrows and manual weeding in rows) and using chemical weeding with manual weeding. It was shown that the content of essential oil in the inflorescences of both examined cultivars was similar.
