The aim of the study carried out under field conditions was to evaluate effect differentiated phosphorus and potassium fertilization level on nutritional status winter wheat at stem elongation (BBCH 31) flowering 65) development stages as well macronutrient contents in yield obtained (grain straw). research conducted 2007-2010, within an individual agricultural holding, lessive soil with medium high richness phosphorus, respectively. nitrogen, potassium, magnesium calcium changed depending organ assessed plant stage. At BBCH 31, regardless level, plants observed were malnourished control site – also nitrogen. Furthermore, there found significant correlation relationships among nutrient pairs: nitrogen-potassium, nitrogen-phosphorus, nitrogen-magnesium nitrogen-calcium. content nitrogen grain straw differed mainly due weather during study. Irrespective years observation, rates P K applied had no N accumulation full ripening In contrast significantly straw. case calcium, factor indicated only regards this grain.
