Improving profitability of flax production in high moisture environments
The advent of canlin cultivars of flax appears to offer the potential for greatly expanded flax acreage providing yields are high enough. Over the period of time 1988-93 average yields of McGregor flax were similar to those of Global canola under irrigated conditions at Outlook Saskatchewan. Scelerotinia and blackleg do not affect flax and both species appear to have similar effects of subsequent cereal grain crops. Delaying planting has reduced yields by 20 % in years where early frosts did not affect yields. Early planting would generally preclude the use of trifluralin since planting into cold soils is not recommended. Flax planted at the end of May can be up to 10 cm taller than crops planted in early May. High seeding rates reduced yields in all 3 years. High seeding rates sometimes induced more lodging, but this affect was not consistent. Narrow row spacings did not increase seed yields. High yields can be obtained over a wide range of seeding rates and row spacings providing weed control is excellent and seeding is done during the first half of May.
