A seeding rate of 50% chickpea and 50% flax resulted in maximum combined yield and land productivity, and reduced Ascochyta blight disease severity by 50 to 67% compared to monocrop chickpea, but flax competed with chickpea and reduced chickpea yield. Ascochyta blight, caused by Ascochyta rabiei,...

Using fungicide and a high nitrogen (N) rate most consistently increased flax yield (11% increase). The combination of high plant density, narrow row spacing, high N fertilizer, and fungicide produced the highest yield response (23% more), but not in unfavorable growing environments. The most well-rounded...

A flax rotation that included 3 years of alfalfa with reduced herbicide applications provided similar wild oat and cleaver control as a flax-barley-flax-oat rotation with recommended herbicide applications. Including 2 successive winter cereal crops in a 5 year rotation also improved wild oat control. Wild oat...

Generally, a black medic cover crop reduced the proportion of small aggregates and increased the proportion of large aggregates. Medic offers a natural way to maintain soil health in low external input cropping systems. Black medic is a self-regenerating cover crop that grows under the crop...

Seeding a tall cultivar at 80 seeds/ft2 in early May along with the application of an in-crop wild oat herbicide resulted in the greatest stand establishment and crop biomass, as well as the lowest weed biomass in flax. Flax is a poor competitor with weeds, and...

On sites testing low in nitrogen (N) fertility, flax yields were 39% higher with rates of 90 lbs. N side-banded per acre. Flax response to phosphorus (P) averaged 7% and rates of no more than 18 to 36 side-banded P2O5 per acre were justified. Phosphorus...

Of the seven unregistered herbicides assessed, flax has excellent crop tolerance to fluthiacet-methyl, pyroxasulfone, and topramezone. Flumioxazin caused severe crop damage in high moisture situations and is not recommended for further trials. Field experiments were conducted in 2015 and 2016 at the Kernen Research Farm and...
