The effect of polyphosphate on total plant yield was similar as of triple superphosphate applied with potassium chloride. Yearly doses resulted in significantly higher yields irrespective of the fertilizer used when compared with the fertilization for future. Phosphorus content in plants and utilization of this element depended on the method of fertilization, but potassium content was higher in the plants fertilization with potassium polyphosphate
