The arrangement of plants in paired spacing is one of the management practices being used in some crops resulting in increased yield. Aiming to evaluate the arrangements and plant density on agronomic characteristics, yield components and yield of two wheat cultivars, one experiment was carried out on a Haplic Cambisol Tb typical dystrophic soil, with two cultivars, in the city of Ponta Grossa, PR,. The design experimental was randomized blocks in a factorial design 2×4, with four replications. The treatments consisted of two plant arrangements (single and paired spacing) and four plant densities (45, 60, 75 and 90 plants m-1), applied in two wheat cultivars (Marfim and BRS-Tangara). At Paired spacing the number of spikes per square meter and yield were lower than single spacing, even with higher grain weight in both wheat cultivars. The paired spacing did not result in increased yield for both wheat cultivars.

 

Key words: Triticum aestivum, tillage, paired spacing.
