Effects of different phosphorus and potassium fertilization on contents and uptake of macronutrients (N, P, K, Ca, Mg) in winter wheat I. Content of macronutrients

Abstract

The aim of the study carried out under field conditions was to evaluate the effect of phosphorus and potassium fertilization level on nutritional status of winter wheat at stem elongation and flowering development stages as well as on contents in yield obtained (grain and straw). The research was conducted in within an individual agricultural holding, on soil with medium and high richness in potassium and phosphorus, respectively. The contents of nitrogen, phosphorus, potassium, magnesium and calcium in wheat changed depending on the organ assessed and plant development stage.
