Abstract
Summary. Characterization of nodule growth and functioning, phosphorus status of plant tissues and host- plant growth of nodulated soybean (Glycine max L. Merr.) plants grown under different phosphorus conditions was studied in order to evaluate the role of phosphorus in symbiotic nitrogen fixation. Phosphorus deficiency treatment decreased the whole plant fresh and dry mass, nodule weight, number and functioning. Under conditions of phosphorus oversupply the decrease in plant growth, nodulation and acetylene reduction was stronger. Phosphorus deficiency significantly affected all phosphorus metabolites. Contents of different phosphorus fractions were decreased under the conditions of phosphorus deficiency.
