The nutritive value of fodder chicory is close to the quality of fodder alfalfa, i.e. under certain technological conditions, fodder chicory has a higher nutritive value and more raw protein. Studies show that over three experimental years, the content of raw protein reached values ranging between 23.69 and 25.26% with mineral fertilisation and between 21.88 and 22.81% with organic fertilisation, compared to only 21.06% in the control variant. Depending on the content of raw protein, the amount of raw protein increased with 40.7% with mineral fertilisation and with 22.4% with organic fertilisation, compared to the control variant.

Increasing the biological nitrogen fixing capacity through inoculation with improved stems of nitrogen fixing bacteria is an important measure of increasing total nitrogen content in legumes due to the supply of fixed nitrogen. Research on perennial legume species sowed in pure culture or in mixture with perennial grass species showed that in the variants inoculated the content of total nitrogen was close to the content of total nitrogen in the variants fertilised with N100. Mean data for the three vegetation years show that bacterial inoculation of the legumes contributes with 11.5% to the increase of the content of total nitrogen in the plants, while fertilisation with N100 has an almost similar contribution (11.0%).
