In the paper reaction of potatoes on PRP SOL fertilization was investigated. Experiments on the assessment of potato variety Satina response to the use of PRP SOL were conducted in 2007-2011 in the field in Złotniki belonging to the Experimental Station Gorzyń, Department of Agronomy, University of Life Sciences in Poznań. The trial was established as one factor, in random block design, in four replications. In the cultivation of potatoes, phosphorus-potassium fertilizers can be replaced by fertilizer PRP SOL, as indicated by no significant differences in tuber yields obtained in tested technologies and yield increase trends occurred in four of the five years of research. The leaves of plants fertilized with PRP SOL characterized in each year of the study a higher greenness index, expressed in SPAD unites, which indicates a better nutritional status of plants. The use of PRP SOL fertilizer can be especially useful for potato seed production, because after using it increases the fraction of potato seed in tuber yield.
