Determining excess moisture effects on different flax varieties (2016)

Crop Types: Flax

Centre(s): PESAI

Over the growing season, flax water use may be as high as 41 cm (16 in.). During the seedling stage, water use will range from 1 to 3 mm/day, rising to a high of 7 mm/day during the flowering stage. The critical water requirement period for flax is from flowering to just prior to seed ripening (Saskatchewan Flax Development Commission). However, excess water at early crop stages might affect flax adversely. Chlorosis can occur on flax when soil moisture is high, particularly on calcareous (high lime) soils and it can significantly affect flax productivity. The flax variety AC Emerson has shown the greatest tolerance to chlorosis conditions (Manitoba Agriculture). Flax reaction to excess moisture varies considerably depending on crop stage and soil type. A recent study from Manitoba shows that irrigation increased total average yield of flax, even when conditions of excess moisture were prevalent in 2016 (Cavers et al, 2017). The current study was undertaken to understand excess moisture effects on different flax varieties. Eight commonly grown flax varieties were planted in a replicated trial both under irrigated and non-irrigated set up to see if there is any irrigation-variety interaction towards flax productivity.

Flax Council of Canada Agronomy Evaluation (2016)

Crop Types: Flax

Centre(s): PESAI

There is a sizeable gap between the yield potential of flax and the average yields observed in the Prairies. Whereas the 10-year average yield for Manitoba is 21 bu/acre (Yield Manitoba 2016), Flax Council of Canada (FCC) has set up an ambitious goal to raise yield levels up to 32 bu/acre by 2025. In order to achieve higher yields on a commercial scale, best management practices (BMPs) are required. FCC planned four flax research trials to develop BMPs for the following elements: A) Seed treatment and fertilizer rates; B) Seeding date, rate and row spacing; C) Herbicides and fungicide use; and D) Crop stubble and flax production interaction.

Manitoba Crop Variety Evaluation (MCVET) (2018)

Crop Types: Barley, Flax, Oats

Centre(s): PCDF

The purpose of the MCVET variety evaluation trials is to grow both familiar (checks or reference) and new varieties side by side in a replicated manner in order to compare and contrast various variety characteristics such as yield, maturity, protein content, disease tolerance, and many others.

Manitoba Crop Variety Evaluation Trials (MCVET) (2017)

Crop Types: Barley, Fababeans, Flax, Oats, Peas, Rye, Soybean, Wheat

Centre(s): CMCDC, PCDF, PESAI, WADO

Manitoba Crop Variety Evaluation Trials (MCVET) facilitates variety evaluations of many different crop types in this province. PCDF’s unique position on the Manitoba Saskatchewan border provides it with opportunities to also work with the Saskatchewan Variety Performance Group. The purpose of the MCVET and SVPG trials is to grow both familiar (checks or reference) and new varieties side by side in a replicated manner in order to compare and contrast various variety characteristics such as yield, maturity, protein content, disease tolerance, and many others. During 2017, PCDF did variety trials in Spring wheat, Fall Rye, Oats, Barley, Faba beans, Flax, Soybeans (both RoundUp Ready and conventional) and Peas. The Winter Wheat trial was discontinued due to spray drift damage, and one Spring Wheat trial was discontinued due to weed issues. From each MCVET site across the province, yearly data is collected, combined, and summarized in the ‘Seed Manitoba 2017’ guide. Hard copies are available at most Manitoba Agriculture and Ag Industry Offices.
