THE ROLE OF COBALT IN FORAGE LEGUMES

Abstract

The growth and metabolism of plants, especially on acidic soils, largely depend on the concentration of cobalt (Co) in the soil, i.e. the rhizosphere. An optimal supply of cobalt is essential for N2 fixation of Rhizobium bacteria that are in symbiotic relationships with leguminous plants, influencing their better growth and supplying them with nitrogen. When there is a lack of Co in the plant, the organic production of legumes falls. Indirectly or directly, Co also affects other metabolic processes in plants. The aim of the work was to analyze the importance of optimal provision of forage legumes with cobalt for obtaining high and quality yields of forage and seeds.
