As for the dry matter content in the young shoots of rare oilseeds, the differences observed were statistically significant (\(p\)\(\leq\) 0.05) depending on the harvest date (Table 1). \begin{table}

Table 1: Dry matter content (g 100 g\({}^{-1}\) FW) and the chemical composition (g 100 g\({}^{-1}\) DW) in young shoots at different stages of vegetation. Dry matter values were lower after the first harvest than after the second harvest (Table 1). A significantly higher (\(p\leq 0.05\)) dry matter content was observed in nigella, compared to amelina and safflower. The average dry matter content of nigella was approximately twice as high as that of safflower and 3.4 times higher than that of amelina. In turn, the dry matter content was the highest in nigella (average of two harvests--5.9 g per 100 g of fresh weight--FW) and the lowest in safflower (1.7 g/100 g FW). All the young shoots of the examined rare oilseeds differed in a statistically significant way (\(p\leq 0.05\)) in the dry matter content. The ash content of the analyzed young shoots ranged from 15.65 to 19.99 g per 100 g dry weight--DW. The average ash content in the young nigella shoots was 17.73 g/100 g DW. There was no statistically significant (\(p>0.05\)) difference in the ash content depending on the harvest date in the young safflower shoots; however, such a difference in this parameter was observed in the young shoots of nigella and amelina. In the young nigella shoots, a higher ash content (by 20.5%) was noted after the first harvest than after the second harvest. A statistically significant difference (\(p\leq 0.05\)) was observed in the total protein content with respect to the harvest date of the nigella young shoots (Table 1). In this case, the protein content was significantly higher (\(p\leq 0.05\)) after the first harvest (by 17.22%) than after the second harvest.
