| Summary: | The amount of fixed nitrogen per decare was studied in the experimental field of Research Institute of Mountain Stockbreeding and Agriculture-Troyan of bird'sfoottrefoil cultivars, such as Targovishte , Alvena, Lotanova and Frilo (Italy), Polom (Slovakia), Bonnie (France), Bull (Canada). The Lotanova and Polom varieties have increased nitrogen-fixing capacity and level of tuber formation, as well as fixed nitrogen per decare ( 7.40 and 7. 7 N fix, kg/da), which is a prerequisite for increasing soil fertility and the ecological effect. These two varieties could be recommended as suitable for implementation in production from an economic and ecological point of view. The correlation analysis proved a high positive correlation dependence of gross revenue with yield (r=0.9999), production costs (r=0.9982), and the amount of fixed nitrogen (r=0.9998). Plant nitrogen storage through symbiotic nitrogen fixation of bird'sfoottrefoil, as a suitable meadow legume species for mountain conditions, determines its ecological effect. |
