In this study nitrogen (N), phosphorus (P) and potassium (K) analysis were carried out during vegetative and generative growth periods. It has been found that above ground parts of plant have higher macroelement concentrations as compared to below ground parts during vegetative growth period. However, below ground parts have higher macroelement concentrations during generative growth phase due merely to top senescence. In addition to this there were significant and mostly negative correlations between plant and soil macroelement concentrations.]]>Allen, S.E., N.M. Grimshaw, J.A. Parkinson, C. Quarmby and J.D.
