“…The authors showed that on a treatment without biostimulants, the concentration of harmful compounds was the highest and averaged to 10.15 µM·g −1 . In other studies by Jankowski et al [18], intensified foliar fertilization significantly reduced progoitrin levels by 41% on average and gluconapin by 46% on average, while in subsequent studies [19], the foliar fertilizers used increased the content of alkene and indole glucosinolates in the dry matter of seeds. Similarly, Filipek-Mazur et al [21], after applying fertilizers containing sulphur, while Davoudi et al, [23] after applying selenium, showed an increase in glucosinolate content in rapeseed.…”

“…After applying foliar fertilization with sulphur and boron in combination with amino acids (4), the value of this feature increased by an average of 1.25 µM/g, while the smallest (average of 1.00 µM·g −1 ) increase in the GLS concentration was recorded in treatment 3, where sulphur and boron were used. Jankowski et al [17], thanks to the effect of foliar feeding with boron, observed a significant increase in the content of alkene glucosinolates (progoitrin) and a decrease in indole GLS (4-OH-glucobrassicin), and in later studies of the authors [19], under the influence of autumn macro and micronutrient feeding, an increase in the content of alkenyl and indole glucosinolates in rapeseed seeds was observed.…”

“…Sikorska et al [14] showed that the population morphotype is characterized by the lowest concentration of these compounds, while Rajtczak et al [13] stated that half-dwarf hybrids. Many authors [19,21,23] under the influence of foliar fertilization showed an increase in the GLS content in rapeseed, while Yang et al [24], Jankowski et al [18], and Sikorska et al [14] found a reduction in the concentration of these compounds in rapeseed.…”

“…Glucosinolates play an important role in the plant in increasing the resistance of plants to stress caused by environmental factors and protecting against pests and diseases. The glucosinolate content depends on the genetic factor [12][13][14][15], agrotechnical procedures [16][17][18][19][20][21], and environmental conditions [14,22]. Sikorska et al [14] showed that the population morphotype is characterized by the lowest concentration of these compounds, while Rajtczak et al [13] stated that half-dwarf hybrids.…”

The study was carried out in 2016–2019 at the Zawady Agricultural Experimental Station (52°03’ N and 22°33’ E) belonging to the University of Natural Sciences and Humanities in Siedlce, in Poland. The field experiment was established in a split-plot design with three replicates. The studied factors were: I. Three winter rape morphotypes: population morphotype (Monolit variety); restored morphotype with traditional growth type (PT248 variety); restored morphotype with a semi-dwarf growth type (PX115 variety); II. Types of foliar nutrition: (1) control variant—sprayed with water, without foliar nutrition and amino acids; (2) biostimulant Aminoplant; (3) foliar fertilizer Siarkomag + foliar fertilizer Bormax; (4) foliar fertilizer Siarkomag + foliar fertilizer Bormax + biostimulant Aminoplant. The aim of the study was to determine the effect of foliar application of sulphur, boron, and amino acids on the content of glucosinolates in seeds of three winter rape morphotypes (Monolit, PX115, and PT248). The foliar feeding applied reduced the feed value of winter rape seeds. On treatments (2, 4), where only amino acids were used or in addition in combination with sulphur and boron, the increase in glucosinolate concentration (GLS) was the largest. Regardless of the type of foliar fertilization used, the Monolit variety contained the lowest concentration of these compounds. The content of glucosinolates in rapeseeds of the studied cultivars varied during the years of the experiment. Studies have shown that the value of this feature increased with the growth of water stress occurring before harvest.

“…; Sokólski, M.; Szatkowski, A. [2], were conducted a 3-year field experiment in north-eastern (NE) Poland to determine the influence of the autumn application of foliar macronutrient and micronutrient fertilizers on the growth and development of winter oilseed rape plants, nutrient accumulation, overwintering success, yield components, yield, nutritional value, and feed value of seeds confirmed that the application of foliar macronutrient and micronutrient fertilizers in autumn increased seed yield (by 0.25 Mg ha−1), contributed to a significant increase in the crude fat content of seeds (by 1.3-7.4 g kg−1 dry matter (DM), increased the content of oleic acid, decreased the concentration of linoleic acid, and increased the content of glucosinolates.…”

It is made the comparison estimation of winter rapeseed quality properties depending on the fertilization level and sowing date in this article. The literature on the research problem is elaborated; there are presented the study importance and relevance of growing technology elements influence on the quality properties of winter rapeseed seeds. It is analyzed the results of sowing periods and different rates of mineral fertilizers influence on the quality indicators of winter rapeseed seeds under the conditions of Right-Bank Forest-Steppe in Ukraine. Significant influence of the studied elements of technology on the main indicators of seed quality was noted; it was found that the change in the yield level obtained by the hybrids led to a change in the oil quality indices. Four the most important oil quality indicators were analyzed in this article. They are: acid value, glucosinolates amount, oil and protein contents. They were affected by different fertilizer rates and sowing dates, which were the experiment conditions. So, the lowest acid value – 1.08 provided hybrid Excel, when fertilizer rate was N240P120K24; when sowing dates were analyzed, the lowest indicator – 1.24 was obtained by Exagon hybrid in the first sowing date – 10th of Aug. the correlation between acid value and rapeseed yield was negative and oscillated from r = - 0.9327 to r = - 0.9843; the magnitude of the approximation reliability oscillated in the range of R2 = 0.87 – 0.97, which evidence the strong dependence between indicators. The lowest content of glucosinolates – 12.51 μmol / g had Excel hybrid under the conditions without fertilizers; when sowing dates were analyzed, the lowest indicator 15.06 μmol / g was obtained by Exagon hybrid in the first sowing date – 10th of Aug. The highest oil content had Excel hybrid – 46.27%, it was obtained in variant of N240P120K240. The protein content of each hybrid was increasing with fertilizer rates expansion. So, the highest indicator of it was obtained in the variant where N240P120K240 was used and it was Exagon – 22.10%. The highest protein content – 21.13% was obtained by Excel hybrid in the second sowing date – the 21st of Aug. when sowing dates were analyzed, and the highest oil content – 46.75% were obtained by Excel hybrid in the third sowing date – 5th of Sept. Key words: winter rapeseed, sowing dates, fertilizers, acid value, glucosinolates amount, oil and protein contents.
