“…In spring Brassica oilseed crops, S fertilization improves NFUE only if the applied N rate is highly effective. Such observations were made by Lošák et al [47], Jiang et al [48], Wysocki et al [49], and Jankowski et al [34] in camelina; by Ahmad et al [45] in Indian mustard and field mustard; by Kovács et al [46] in white mustard; by Sokólski et al [44] in crambe; and by Wielebski et al [43] in winter rapeseed.…”

“…In the current study, an increase in the N rate from 0 to 120 kg ha −1 decreased NFUE by 48% (4.22 vs. 2.19 kg of seeds per 1 kg of N). Higher N rates also decreased NFUE in the production of camelina [34,62], crambe [44], white and Indian mustards (regardless of grade), field mustard, spring rapeseed [35], and winter rapeseed [43].…”

“…Sulfur deficiency decreases TP content, increases nitrate concentration, and promotes proteolysis in plants [41]. In turn, an adequate S supply increases nitrogen fertilizer use efficiency (NFUE) and nitrogen agronomic efficiency [41][42][43]. Sokólski et al [44] demonstrated that in crambe cultivation, S fertilizer increased NFUE by 22-39%.…”

Nitrogen (N) and sulfur (S) fertilization significantly affect seed yield and quality in Brassica oilseed crops. The effect of N and S management on the crop parameters (plant height, stem-base diameter, and number of branches), yield (seed yield components, seed and straw yields, harvest index—HI), and the quality of the seeds and oil (crude fat—CF, total protein—TP, crude fiber—CFR, fatty acids profile—FA, acid detergent fiber; and neutral detergent fiber) of oilseed radish (Raphanus sativus L. var. oleiformis Pers.) was analyzed in the study. The effect of N and S fertilization was evaluated in a field experiment in Bałcyny (north-eastern Poland) in 2020–2022. The experiment had a split-plot design with two factors and three replications. The first factor was the N rate (0, 30, 60, 90, 120 kg ha−1) and the second factor was the S rate (0, 15, 30 kg ha−1). Nitrogen fertilization stimulated stem elongation and branching. The average oilseed radish (OSR) seed yield ranged from 0.59 to 1.15–1.25 Mg ha−1. Seed yields increased significantly, up to 90 kg N ha−1 and 15 kg S ha−1. The N fertilizer use efficiency (NFUE) of OSR decreased with a rise in the N rate (from 4.22 to 2.19 kg of seeds per 1 kg N). The application of S did not increase NFUE. The HI ranged from 10% (0–30 kg N ha−1) to 12% (60 kg N ha−1). The contents of CF, TP, and CFR in OSR seeds (kg−1 dry matter—DM) were 383–384 g, 244–249 g, and 97–103 g, respectively. Nitrogen fertilization decreased the CF content (by 5%) and increased the contents of TP (by 5%) and CFR (by 16%) in OSR seeds. Sulfur fertilizer applied at 30 kg ha−1 decreased the CF content (by 2%), but it did not alter the content of TP or CFR. Oilseed radish oil contained 68–70% of monounsaturated FAs (MUFAs) (erucic acid accounted for 2/3 of the total MUFAs), 24–25% of polyunsaturated FAs (PUFAs), and 6–8% of saturated FAs (SFAs). Nitrogen fertilization increased the proportions of SFAs and PUFAs in OSR oil. Nitrogen rates of 60–90 kg ha−1 increased the contents of alpha-tocopherol (α-T), beta-tocopherol (β-T), and gamma-tocopherol (γ-T) in OSR seeds by 32%, 40%, and 27%, respectively. Sulfur fertilization increased the content of PUFAs and decreased the content of MUFAs in OSR oil, while it increased the contents of α-T (by 15%) and γ-T (by 19%) in OSR seeds. Proper N and S management in OSR cultivation can improve crop productivity and the processing suitability of seeds.

“…Groth et al [43] reported a 3-4% increase in WOR yields in response to an S rate of 40 kg S ha −1 . In turn, Wielebski et al [66] found that 30 kg S ha −1 was the most effective S rate in WOR production (seed yields increased by 5%), whereas 60 kg S ha −1 did not induce a further increase in yields. In the present study, the greatest increase in seed yields (11%) was observed in treatments fertilized with 40 kg S ha −1 .…”

“…Numerous researchers have demonstrated that the effectiveness of N fertilization (in particular at high N rates) in the production of Brassica plants is enhanced when crops are adequately supplied with S [43,49,66,67]. Wielebski et al [66] found that in treatments fertilized with 220 kg N ha −1 , the application of 60 kg S ha −1 increased WOR yields by around 8%. In a study by Jankowski [59], the highest N rate (240 kg ha −1 ) increased yields only when combined with an S rate of 30 kg ha −1 applied in early spring.…”

The aim of this study was to analyze agronomic management in the production of winter oilseed rape (WOR) in different tillage systems. The field experiment (Poland, 2016–2019) had a 35–1 fractional factorial design with two replications, where five fixed factors were tested at three levels. The experimental factors were as follows. A—tillage: (A0) strip-till, (A1) low-till, (A2) conventional tillage; B—weed control: (B0) pre-emergent, (B1) foliar, (B2) sequential; C—growth regulation: (C0) none, (C1) in fall, (C2)—in fall and spring; D—rate of spring nitrogen (N) fertilizer: (D0) 160, (D1) 200, (D2) 240 kg ha−1; E—rate of spring sulfur (S) fertilizer: (E0) 0, (E1) 40, (E2) 80 kg ha−1. Seed yields were the highest in the strip-till system (5.95 Mg ha−1). The effectiveness of weed control methods varied across different tillage systems. Foliar herbicides exerted the highest yield-forming effect in the strip-till system, pre-emergent and sequential herbicides were most effective in the low-till system, and pre-emergent herbicides were most effective in the conventional tillage system. Seed yields increased up to the N rate of 200 kg ha−1. The highest N rate of 240 kg ha−1 was justified only when S was applied in spring. Sulfur significantly increased seed yields (by 17%). The results of the study indicate that low-till and strip-till systems can be viable alternatives to the conventional tillage system in WOR production.

The article presents the results of a three-year field study that was conducted in Poland to evaluate the yield and quality of seeds and oil from traditional (SAM) and canola-quality white mustard (SAC) in response to different N fertilizer rates (0, 40, 80, 120, and 160 kg ha–1). Seed yields were 25% higher in SAM than SAC. The seeds of SAC contained more crude fat (by 3%) and crude fiber (by 6%) than the seeds of SAM. In turn, the seeds of SAM were a richer source of total protein (by 7%). The content of glucosinolates (GSLs) was 8–10 times lower in the seeds of SAC than SAM. The seeds of both mustard cultivars were most abundant in γ-tocopherol (γ-T) (90–94%). The seeds of SAC were characterized by a higher content of γ-T and a lower α-T/γ-T ratio than SAM seeds. White mustard oil contained mostly MUFAs (69–75%). However, C22:1 accounted for more than 50% of MUFAs in the oil SAM. In the oil SAC, the proportion of C22:1 did not exceed 6%, whereas C18:1 accounted for nearly 85% of total MUFAs. Nitrogen fertilization induced a significant increase in seed yields (by 33%), a decrease in crude fat content (by 3–4%), and an increase in total protein content (by 4%), and crude fiber content (by 7%). Nitrogen decreased GSL levels by 31% in SAM seeds. In SAC, N fertilization induced differences in the qualitative composition of GSLs, but did not affect the total GSL content of seeds. Higher N rates increased the content of α-T and γ-T, the α-T/γ-T ratio, and total T content. Nitrogen fertilization decreased the content of C18:3 in the seeds of the SAM. In SAC, the application of N decreased the content of C18, C18:1, and C18:3, and increased the biosynthesis of C18:2, C20:1, and C22:1.
