Abstract

The aim of this work was to highlight the effects of row spacing and seed densities on the agronomic performance of flaxseed. The trial was developed in the experimental area of the Regional Institute of Rural Development, which belongs to the Regional University of the Northwest of the Brazilian State of Rio Grande do Sul. The experimental design was randomized blocks, and the treatments were structured in factorial scheme three (spacings) x six (densities) with three replications per treatment, totaling 54 experimental units. We used three spacings between rows, 18 cm, 36 cm and 54 cm, and densities of 30, 60, 90, 120, 150 and 180 seeds per linear meter. The experimental units were three meters wide by 10 meters long, totaling 30 square meters. Morphological and productive variables of the flaxseed crop were evaluated, as well as meteorological variables. Increased spacing contributes to reduced grain yield regardless of the sowing density. The row spacing of 18 cm shows the best results for grain yield in relation to the seed densities used. High magnitude linear associations such as number of stem branches, productive branches, number and mass of capsules and grains per plant, and plant population define grain yield per unit of area.
