Pot marigold (<i>Calendula officinalis</i> L.) is an annual ornamental plant which is also grown for herbal raw material (flower heads) used in the pharmaceutical and cosmetic industries. A field experiment was carried out in the years 2006-2008 in the Experimental Farm of the University of Life Sciences in Lublin. The study was conducted on loess soil with the granulometric composition of silt loam. The aim of the experiment was to determine the effect of different nitrogen rates (0, 40, 80, 120, 160 kg N × ha<sup>-1</sup>) on some morphological features of flower heads as well as on yield and quality of pot marigold raw material. Flowering of pot marigold was shortest in the control treatment (32 days) and longest (43 days) in the plot where nitrogen fertilization had been applied at the highest rate (160 kg N × ha<sup>-1</sup>). Nitrogen fertilization had a significant influence on the number of flower heads per plant, but no significant difference was found in diameter as well as in ligulate flowers and tubular flowers in the flower head. It was found to increase significantly raw material yield after the application of 80 kg N × ha<sup>-1</sup>, compared to the control treatment. Yield of flower heads did not differ markedly for fertilization rates from 80 to 160 kg N × ha<sup>-1</sup>. Nitrogen fertilization modified slightly essential oil content (this content increased with increasing nitrogen rates), but at the same time it decreased the percentage of flavonoid compounds.

Pot Marigold

This paper presents the results of a study on the effect of different N fertilization and seeding rates on yield and some quality parameters (of seeds) of pot marigold. A field experiment was carried out during 2014–2016 under soil and climatic conditions of Belarus (Priluki Research Station near Minsk). The experiment included the following factors: N fertilization rate 40, 60, 80, 100 kg ha–1; plant density per 1 m2 (30, 50, 70, 90).  The experiment was set up as a randomized block design in five replicates, with a single plot area of 8.0 m2. The soil in Priluki was characterized by medium nutrient availability (at the level: P = 120–127, K = 164–174, Mg = 59–66 mg kg–1 soil). Regardless of the experimental factors, weather conditions had a significant impact on pot marigold productivity. The year 2016, characterized by an even distribution of rainfall during the growing season and moderate air temperatures, proved to be most beneficial for pot marigold productivity and quality. Hydrological conditions in the other years (2014 and 2015) there was a slight drought. The year 2014 should be considered to be cold, whereas the second year of the study (2015) was moderately warm. Best production effects (seed yield, fat yield) were obtained at rates of 60–80 kg N ha–1. This rate of nitrogen fertilization also modified the fatty acid composition, contributing to a higher content of linoleic acid and calendic acid (∑ α-calendic and β-calendic acids). A nitrogen rate of 100 kg N ha–1 proved to be irrational in terms of the quantity and quality of pot marigold yield. A density of 50–70 plants per 1 m2 resulted in the highest seed and fat yield per unit area. A plant density of 50 plants per 1 m2 resulted in the highest content of C18 unsaturated acids (stearic acid, oleic acid, linoleic acid) in the oil.

Summary In 2007-2009, a pot experiment was carried out in a greenhouse at the University of Warmia and Mazury in Olsztyn on cv. Promyk pot marigold (Calendula officinalis L.). The aim of the study was to assess the impact of nitrogen and magnesium in plant growth and development and yield of marigold. The experiment included two factors: nitrogen fertilization (g.pot-1): A-0 (control), B-0.3, C-0.6 (0.6+0), D-0.9 (0.6+0.3), E-1.2 (0.6+0.6) and magnesium fertilization (g.pot-1): a-0 (control), b-0.5. The experimental part of the research was designed according to the independent series method and set up in 4 replicates, 4 pots in one replicate, in modified Kick-Brauckmann pots. The experiment demonstrated a significant effect of nitrogen fertilization on the plants hight, number of pot marigold inflorescences, fresh inflorescences weight, fresh and airdry ligulate weight. Magnesium fertilization had a positive effect on all the analyzed traits. No statistical correlation was proven between the nitrogen and magnesium fertilization

SUMMARYSoya beans grown on land planted the previous year with inoculated soya beans produced more nodules, lodging, seed yield, 1000 seed weight, and protein content and less seed oil concentration as compared to those grown on land that was planted with non-inoculated soya beans. Nitrogen fertilization (120kg N/ha) reduced the total number of nodules per plant. Increasing inoculation rates of the seed increased the dry weight of nodules per plant. Location, nitrogen fertilization, and inoculation increased or decreased the levels of certain amino acids but had no significant effect on the sulphur amino acids, cystine and methionine.
