摘要

Greenhouse experiments were conducted to investigate the effect of humates on the growth of tomato plants in hydroponic systems. The investigations were carried out using different substrates (perlite, coconut fibre and peat-based substrates) and different concentrations and forms of humates (K-, Na- and NH4-humates). In general, treatments with humic acid increased seed germination, improved plant growth, and increased the content of Ca in shoots, leaves and fruits of tomato. However, significantdifferences were observed with different concentrations and forms of humates and the type of substrate used.
