Yet, no standards exist for optimum plant density. The aim of the study was to determine how crop density affects amaranth morphology, biological grain production and combine yield. A field experiment was conducted under semiarid conditions (9.8 °C, 546 mm) in Eastern Austria during 2002, 2004 and 2005. Two adapted genotypes (Amaranthus cruentus, Amaranthus hypochondriacus) were established at five densities (8, 17, 35, 70, 140 plants m?2) by hand thinning at a row spacing of 37.5 cm. The obtained densities at harvest averaged across years and genotypes were 8, 15, 32, 54, 89 plants m?2. Plant samples were hand-harvested for the determination of morphological characters, grain and total shoot biomass. Subsequently a plot combine was used for harvesting the plots. Rising plant population reduced the number of branches and the stem diameter from 11 plant?1 and 19 mm for the lowest density to 2 plant?1 and 8 mm for the highest density, respectively. Overall plant height decreased with rising density except for 2004 when plan
