M maize, B broad bean, L white lupine, MB maize + broad bean (17.5:1), ML maize + white lupine (3.33:1), DM dry matter, TN total nitrogen content
Average values of available nutrients and dry matter are displayed (n = 3; ± SE)
The values of nutrient contents were converted to the value of dry matter
Different letters indicate statistically significant differences (p ≤ 0.05) in the ANOVA posthoc Duncan’s multiple range test between individual variants in the content of selected parameter
