Impact of production practices on fiber yield of oilseed flax under Canadian prairie conditions.

Flax (Linum usitatissimum L.) cultivars commonly grown in western Canada have been developed primarily for seed production. These cultivars tend to be shorter, have lower fibre content, and have lower above-ground biomass than cultivars developed specifically for fibre production. Linseed production is the dominant flax product in western Canada and fibre is a co-product of oilseed production. The objectives of these studies were to evaluate the effects of northern European fibre flax production practices under western Canadian soil and climatic conditions. A number of cultivars in narrow band and solid-seeded planting geometries to determine if they had similar responses. When flax was planted at recommended seeding rates for linseed production, seed and fibre yields were not affected by planting geometry. Increasing the seeding rate from 40 to 120 kg ha-1 did not affect seed yield regardless of location or seeding date. Even though fibre content was not affected by seeding rate, higher seeding rates inc...
