One fungicide application at mid-flowering was as effective as a dual fungicide application at early- and mid-flowering stages for disease control, quality parameters and yield increases. A dual mode-of-action foliar fungicide is recommended for fungicide insensitivity management. Pasmo is a fungal disease, caused by the pathogen...
Safflower and sunflower demonstrated potential as trap crops to reduce Lygus damage to faba beans. The Lygus pest complex in the Canadian Prairies is dominated by L. lineolaris, L. keltoni, L. elisus, and to a lesser extent, L. borealis. While Lygus have a broad host range,...
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,...
A long-term study at Indian Head, Saskatchewan evaluated the effect of medic on grain yield, N and P of flax, wheat and oats with three different N treatments. Overall, medic had the greatest impact on crop productivity at the low N rate of 20 per...
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...
Managing flax residue with vertical tillage, tandem disc, or rake and burn did not produce significantly higher yield for three subsequent wheat, pea and canola crops than chopping and spreading straw with the combine. Limited differences in soil attributes were observed, and they were diminished...
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...
