The aim of this study was to determine the effect of nitrogen (0, 30, 60, 90, 120 kg ha⁻¹) and sulfur (0, 15, and 30 kg ha⁻¹) fertilization on the morphometric parameters of plants, seed yield components, seed and straw yield, N fertilizer use efficiency (NFUE), and quality of crambe seeds. The experiment had a randomized complete block design, and it was carried out in Bałcyny (northeastern Poland) in 2017–2019. In northeastern Poland, the average seed yields ranged from 0.96 to 1.64–1.82 Mg ha⁻¹ (hulled seeds). Seed yield increased significantly in response to 120 kg N ha⁻¹ and 15 kg S ha⁻¹. The NFUE of crambe decreased by 28% with a rise in N rate. Hulled crambe seeds accumulated 324–394 g kg⁻¹ DM of crude fat, 208–238 g kg⁻¹ DM of total protein, and 118–137 g kg⁻¹ DM of crude fiber. Nitrogen fertilization decreased the crude fat content (by 6%), and it increased the total protein content (by 11%) and the crude fiber content (by 14%) of crambe seeds. Sulfur fertilization increased crude fat content (by 4–5%) without inducing significant differences in the total protein content and the crude fat content of seeds.

Crambe：氮和硫对种子产量和品质的影响-以波兰东北部为例

这项研究的目的是确定氮（0，30，60，90，120 kg ha ^-1）和硫（0、15和30 kg ha ^-1）施肥对植物，种子形态参数的影响产量组成，种子和稻草产量，氮肥利用率（NFUE）和蛤ram种子的质量。该实验采用随机完整块设计，于2017–2019年在Bałcyny（东北波兰）进行。在波兰东北部，平均种子产量为0.96至1.64–1.82 Mg ha ^-1（去壳种子）。响应120 kg N ha ^-1和15 kg S ha ^-1，种子产量显着增加。随着N含量的增加，克拉姆布的NFUE下降了28％。脱壳的蛤seeds种子累积了324–394 g千克^-1 DM粗脂肪，208–238 g kg ^-1 DM总蛋白，和118–137 g kg ^-1 DM粗纤维。施氮减少了蛤seeds种子的粗脂肪含量（降低了6％），并增加了总蛋白质含量（提高了11％）和粗纤维含量（提高了14％）。硫肥可增加粗脂肪含量（4-5％），而不会引起总蛋白质含量和种子粗脂肪含量的显着差异。
