Trials were conducted in Prague (50 NL, 15 EL) to study the effect of sowing rates on the production parameters of the "K343" amaranth. No significant differences in the leaf area index (LAI) were recorded between stands sown at rates of 16 and 65 plants per 1 m2: at the former sowing rate the LAI was 3.6 m2.m-2, at the latter it was 3.2 m2.m-2. There were considerable differences in the number and size of the leaves. LAI compensation by ampler branching was observed at the lower spacing. Increased branching in the thin stand also influenced the proportion of leaves and stems in the total dry matter and the over-all distribution of dry matter in different organs during the growing season.
