The Effect of Mg Foliage Fertilization on Beetroot (Beta vulgaris ssp. esculenta var. rubra) Morphology, Quality Traits and their Relations

Abstract

Mg-treatment increased solid soluble content in roots probably due to the larger assimilation area. The applied foliage fertilization affected inner colour intensity and uniformity in roots positively. The 2% Mg-sulphate solution affected pigment quantity favourably depending on varieties. Close correlation (r=0,71) was found between the yellow (BX) and red (BC) pigments which indicates a similar biosynthetic pathway of the two compounds. The Mg-sulphate foliage fertilization improves quality considerably but the individual reaction of varieties needs further studies.
