Abstract

The aim of this study was to evaluate the effect of the weed competition with different spacings in the culture of flaxseed (Linum usitatissimum L.). The experiment was conducted at the Campus of Unioeste - Cascavel, Paraná State, using the split-plot design in which the plots consisted of presence and absence of weeds and subplots consisted of row spacings (0.15, 0.30, and 0.45 m) with six replications. Plant height, number of capsules, stems and seeds per plant and yield (kg.ha-1) were determined. The increase of spacings between rows and the coexistence with the weed community were detrimental to production components of flaxseed.

Key words: Linunm usitatissimu L., competition, spatial arrangement of plants.
