The starting material for the production of natural dyes are mainly plants. Coloring substances are usually obtained from various parts of plants: flowers, berries, roots, leaves containing pigments, the color of which is due to the presence of compounds such as anthocyanins, carotenoids, chlorophyll, flavonoids, etc. The most promising plant from the point of view of obtaining a yellow colorant is a medicinal calendula (Calendula officinalis L). Coloring pigment is mainly in the epidermis of the corollas of flowers and belongs to the group of carotenoid dyes, giving a yellow color. Its content in the flowers of calendula depends on the variety and growing conditions. Inflorescences of calendula officinalis contain carotenoids 2.8 %, the organic acid is 7.8 %, tannins to 0.02 %, essential oil of 0.03 %, mucus 4 %, ascorbic acid was 4.2 %. The chemical composition of calendula flowers, allows them to be used for dye. A method of extracting coloring substances from the inflorescences of calendula is developed.

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.

The cultivation of catch crops left on the surface of the field in the form of mulch promotes sustainable farming practices, while protecting the biodiversity of agricultural landscape. The paper presents results of research from 2013–2016, aimed at determining the usefulness of catch crops of millet, buckwheat, white mustard, bird’s-foot and Egyptian clover for soil mulching in winter garlic cultivation. The effect of soil litter on the amount of garlic crop in cultivation for bunch harvest and nutritional value determined by chemical composition of edible parts was determined. In the edible part of garlic, the content of dry matter, total and reducing sugars, L-ascorbic acid, total ash, crude fiber, phenolic acids and essential oil was evaluated. The control consisted of plots without mulch plants. In the cultivation of garlic under organic mulch, there was no decrease in commercial yield and no negative competitive effect on yielding. Garlic plants cultivated with mulch plants were characterized by increased height and developed more leaves. The catch crops used in the form of mulch did not affect the dry matter and total ash content in garlic bulbs. In the cultivation with plant litter, the concentration of phenolic acids and essential oil in the leaves was higher and the content of crude fiber was lower, compared to the cultivation without litter. Biomass from catch crops from clover and mustard increased the content of L-ascorbic acid, at the same time reducing the content of total and reducing sugars in the edible part of garlic, except for mulch plants of the bean family. The chemical composition of garlic was affected by different thermal and precipitation conditions in the years of research. In 2016, the year with the highest total rainfall, plants accumulated more dry matter, L-ascorbic acid as well as total and reducing sugars than in 2014 and 2015, years with less rainfall. Our research indicates that there are prospects for practical application of catch crops in the form of mulch for garlic cultivation to enhance the level of nutrients, without compromising the yield.

Pot Marigold (Calendula officinalis L.) is an annual ornamental plant with yellow to orange flowers which belongs the the Asteraceae family, its flowers are used in the pharmaceutical, cosmetic and food industries. The commercial samples of seeds (n=24) of C officinalis were cultivated in home gardens in Estonia. Total carotenoid contents, determined spectrophotometrically (λ=455 nm) in the inflorescences, varied from 0.7 to 2.7%, the cultivar with the highest carotenoid content was ‘Dracon’. The total content of flavonoids, determined spectrophotometrically (λ=370 nm), varied from 0.8% to 1.7%. The best cultivar contained almost maximum amount of total carotenoids (2.5%) and flavonoids (1.7%) was ‘Radio”. The oil yields of eight cultivars of C officinalis obtained were from 0.10 to 0.43%, the highest yield (0.43%) of the oil was obtained from the cultivar ‘Double Ball’. A total 70 compounds were identified and analysed by GC-MS in the essential oil of C officinalis, representing over 95% from total oil. The major components of the oils (>5%) of C. officinalis cultivars were α-cadinole (18.4-32.0%), γ-cadinene (9.7-18.9%), viridiflorol (2.0-10.0%), τ-cadinole (4.7-7.9%), δ-cadinole (3.3-5.6%), and γ-muurolene (0.8-5.1%). There is no clear relation between the colour of the inflorescences of C. officinalis and the total content of flavonoids and carotenoids. The chemotypes of essential oils of C. officinalis were not found among the cultivars studied.
