Objectives
To demonstrate the effects of low, medium and high seeding rates at early and late seeding dates on flax establishment and seed yield.
Project Description
Indian Head Agricultural Research Foundation conducted a field demonstration on behalf of SaskFlax to demonstrate the effects of seeding date and seeding rate on flax establishment and seed yield. A factorial combination of two seeding dates (early May and late May) and three seeding rates (40, 55 and 70 kg/ha) were arranged in a split plot design with seeding date as the main plot, seeding rate as the sub-plot and four replicates.
Flax performed well at both seeding dates. Days to maturity was substantially reduced with delayed seeding and was also reduced significantly with increasing seeding rate. Despite the higher populations achieved with delayed seeding, the yield response to increasing seeding rate was similar to that observed with early seeding.
