Summary
A field experiment was carried out with 20 maize hybrids growing on a calcareous chernozem and their chemical composition was determined at the 8–10 leaf stage. The nutrient concentration varied from hybrid to hybrid but were within the sufficiency range. Of the elements studied only N has shown a correlation between the concentration and yield (r = 0.53). The hybrids are characterized by comparatively constant percentage ratios of macronutrients and micronutrients, while the macro and micronutrient totals as well as N/K, K/Ca, N/P, Fe/Zn and Fe/Mn ratios vary. No regular relationship has been observed between the efficiency of the hybrid, assessed on the basis of its ability to accumulate a nutrient, and the yield it produces.
