We have examined the results of increasing rates of PK fertilization on the Debut test variety of white clover, bred at the IUSBA Troyan (Bulgaria), and grown on light-grey, pseudopodzolic soil. The variety can be classified in the form of giganteum and is intended for both grazing and hay production. The highest fresh herbage yield was obtained after reserve fertilization (duration 3 years) with P240 and K240, as well as after the annual application of P120K120. From an economical point of view, the best results were obtained after annual separate application of either P60 or K60.
