### Nutritional Composition of Camelina Oilseed Cake  
The influence of the soil tillage system and organic fertilization on the dry matter (DM) content of amelina oilseed cake is shown in Table 5. During the two-year experiment, DM content was not affected by soil tillage systems; however, the experiment results showed that the mean values of this trait offered strong evidence of the effect of varied organic fertilization treatments. In particular, the highest values were presented for compost fertilizer (93.54% and 93.70% in 2015 and 2016, respectively), followed by vermicompost (93.11% and 93.46% for the corresponding growing seasons). Both soil tillage and organic fertilization had a significant impact on crude protein (CP) content (Tables 3 and 5). Concerning the soil tillage effect, the CP content mean values in conventional tillage plots (35.60% and 35.18% DM in 2015 and 2016, respectively) were substantially higher than that in minimum tillage plots (33.99% and 33.71% DM for the corresponding growing periods). As regards the fertilization effect, the highest mean values of CP content were discovered in plots with compost (35.53% and 35.16% DM in 2015 and 2016, respectively) and vermicompost (34.91% and 34.64% DM for the respective years) fertilizers, whereas the lowest values (33.94% and 33.54% DM for the corresponding growing seasons) were achieved in the unfertilized (control) plots. \begin{table}

Table 4: _Cont._The current study found that soil tillage had a substantial impact on the crude fat (CF) content of amelina oilseed cake during the experimental periods (Table 5), with the minimum tillage plots achieving higher values of this measure (17.93% and 16.01% DM in 2015 and 2016, respectively) in relation to the conventional tillage treatment (15.47% and 14.87% DM for the corresponding growing seasons). As regards organic fertilization, this also had a considerable effect on the CF content, with greater values (17.88% and 16.02% DM in 2015 and 2016, respectively) observed in plots fertilized with compost fertilizer followed by vermicompost (16.69% and 15.79% DM for the corresponding experimental years).
