The studies were carried out on the plant material taken from the first and the second regrowths in the second harvest year of Trifolium repens. Fertilization in experiment equated to a dose of 90 kg ha⁻¹ N, 44 kg ha⁻¹ P and 66 kg ha⁻¹ K. Three cultivars of white clover: 'Rema', 'Rawo' and 'Alice' were chosen for chemical analyses. Clover plants were divided on leaflets, petioles and heads with peduncles. The content of N was determined by the Kjeldahl method, P colorimetrically, K, Ca, Mg and Na by spectrophotometry of atomic absorption. There was confirmed that the content of nutrient in Trifolium repens was varied in dependence on white clover cultivar, a part of plant and canopy structure in the following plant regrowths. 'Rema' cultivar accumulated more N, P and K while 'Rawo' cultivar more Ca and Mg. Leaflets of white clover were conspicuous by N and Ca content. Its petioles contained more K, Mg and Na and heads with peduncles were abundant in P. Higher concentration of the main macroelements in the plants of spring regrowth and abundance of Ca, Mg and Na in dry matter of summer plant regrowth were the consequence of changes in canopy structure during vegetative period.
