“…In soils that are deficient in nutrients, including B, foliar application of B can increase the seed yield of rapeseed crops by even several dozen percent. In a study by Varenyiova and Ducsay (2014), foliar application of B at 200, 400 and 800 g B ha -1 in Slovakia (brown Podzolic soils) increased the seed yield of winter oilseed rape by 31%, 42% and 48%, respectively. In central China, the seed yield of rapeseed grown on sandy soils with a low B content (0.06 mg kg -1 ) increased by 67% in response to foliar application of B and Mo, by 55% in response to foliar application of B and Zn, and by 68% in response to foliar application of B, M and Zn.…”

“…Rapeseed plants are most sensitive to B deficiency during flowering because this micronutrient is essential for pollen production (Xu et al 2001). Yang et al (2009) demonstrated that B fertilization of rapeseed can intensify the transport of photosynthesis products from the pericarp to seeds, which increases seed yield (Krauze et al 1991, Bowszys 2001, Xu et al 2001, Varenyiova and Ducsay 2014, Ma et al 2015, Sienkiewicz-Cholewa and Kieloch 2015 and improves the nutritional and feed value of seeds (Krauze et al 1991, Bowszys 2001, Malhi et al 2003, Eggert and Wirén 2016.…”

This paper presents the results of a 3-year field experiment conducted on soil with moderate levels of boron (B) in north-eastern Poland to determine the influence of foliar application of B (0, 150 and 300 g ha-1) on the yield components, yield, mineral composition, nutritional value and feed value of winter oilseed rape seeds. Foliar application of B at the beginning of bud formation in winter oilseed rape increased seed yield by 0.19 (3%) at the lower B fertilization level to 0.26 Mg ha-1 (4%) at the higher B fertilization level. The observed increase in the yield of winter oilseed rape seeds in response to foliar application of B can be attributed to this micronutrient’s positive influence on seed production in siliques. Foliar fertilization with B increased B content and decreased Zn and Fe levels in the seeds of winter oilseed rape. When B fertilizer was applied at the rate of 150–300 g ha-1, the N and Ca content of the evaluated seeds increased. The fertilizer improved the nutritional value (crude fat content, fatty acid concentrations) of seeds, but deteriorated their feed value (total protein content, acid detergent fiber concentrations, neutral detergent fiber concentrations, quantitative and qualitative composition of glucosinolates).

“…The increase in the N rate appears to be associated with a slight reduction in the oil content in the seed although the differences were not statistically significant and should be associated with the increase in protein content, since the oil plus the protein content tend to be constant in the seed of the rape (Brennan et al 2000). In previous studies a significant reduction was found between N rate and seed oil content (Šiaudinis and Butkute 2013;Varényiová and Ducsay 2016). In any case, the oil content in the seeds was lower than that recorded by Brennan et al (2000), which probably is a reflection of the very poor humidity conditions late in the growing seasons during grain filling (Figure 1).…”

Rapeseed acreage has been increasing fast in the last few decades and cultivated areas have expanded into lower latitudes because of the high value of its seed. This work evaluates the effect of date of sowing and nitrogen (N) fertilization on crop productivity and N use efficiency in a Mediterranean environment. The experiment was arranged in a split-plot design with the dates of sowing as the main-plots and N rates the sub-plots. Rapeseed recovered 128 to 212 kg N hm -2 before top-dress N application in late winter if sown before the last week of September. Seed yield was very dependent on the date of sowing, varying from 3.4 to 6.2 Mg hm -2 on the first sowing date in September to 0.3 to 1.0 Mg hm -2 on the last sowing date in November. The daily loss in seed production was 68.9 kg hm -2 (or 482.3 kg hm -2 per week) or 1.53 % (or 10.7 % per week). N rate significantly increased seed yield within each sowing date but did not allow latesowed plants to regain the productivity levels of those sown earlier. Apparent N recovery and agronomic N efficiency were particularly dependent on the growing conditions associated to different sowing dates. ARTICLE HISTORY

“…The content of fat in seeds is mainly determined by genetics (Tanska et al, 2009;Wittkop et al, 2009;Ambrosewicz-Walacik et al, 2015), although it may change being influenced by habitat conditions (Ozturk, 2010;Spychaj-Fabisiak et al, 2011;Faraji, 2012;Varényiová and Ducsay, 2016). The fat yield was strongly correlated with seed yield (r = 0.…”

Quality features of rapeseeds (Brassica napus L.) and potential for high yielding to a major extent may be defined by improvements in agricultural engineering methods that encompass biological progress. However, this is associated with fertilization and application of pesticides, which may negatively impact on environment and quality. It is thus essential to develop and improve edible oil production systems to satisfy farmer and non-threatening consumer. The aim of this study was to evaluate content of nutrients, fat yield and fatty acid profile of rapeseed grown in two crop rotation system with three levels of agricultural inputs. Three levels of technologies were used: economically (low-input), moderately intensively (medium-input) and intensively (high-input), varied in N amount and S fertilization as well as protection against pests. The medium-and high-input technologies applied in the monoculture contributed to an increased oleic acid in rapeseeds (by 5.7% and 5.5%), whereas low-input and high-input technologies resulted in an increased proportion of linoleic (by 11.6% and 2.1%) and linolenic acid (by 6.6% and 5.0%) in the monoculture rapeseeds. The medium-input level generated an increased proportion of arachidic (from 6.9% to 15.0%), octadecanoic (by 4.9%), linoleic (by 7.0%), linolenic (by 5.1%) and eicosadienoic fatty acids (by 17.7%) in rapeseeds cultivated in the crop rotation system. The increase in technological input level changed the ratio of polyunsaturated fatty acids to linoleic and linolenic acids by 5.1% and 7.4% (p < 0.05) in both crop rotation and by 4.2% and 7.9% monoculture systems. In general, the impact of winter rapeseed in crop sequence systems was found to have an insignificant impact on the content of macronutrients and trace elements in seeds. The highest fat yield was generated with the crop rotation system at the highest input level, whereas the lowest yield was recorded in the low-input monoculture technology.
