28 Oct Economic performance of legume intercrops varied

Posted at 20:57h in Agronomy

The economic returns of cereal, oilseed and legume intercrop crops varied by location. Generally, intercropping reduced losses or outperformed less profitable monocrops but high value monocrops like corn and soybean outperformed intercrops. Net return stability also varied by different intercrop types and growth conditions. Legume intercrops...

28 Jul Legume intercrops with oat or mustard in organic cropping systems

Posted at 21:41h in Agronomy

Under drier than normal conditions, this study shows that intercropping legumes and non-legumes can outperform organic crop monocultures in productivity, grain weight and grain protein in the semiarid region of the Canadian prairies. Organic intercrops with non-legumes also play a role in reducing weed pressure,...

30 Aug Agronomic benefits of black medic cover crops

Posted at 21:52h in Agronomy, Soils and Fertility

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...

26 Jul Managing perennial broadleaf weeds in oat

Posted at 21:28h in Weeds

Combining a post-emergent herbicide application with a subsequent pre-harvest glyphosate application resulted in the best dandelion control. Growers should consult with their oat buyer to ensure that they will accept oats treated with pre-harvest glyphosate. The objective of this study was to determine if cultural practices...

15 Jul Researching pre-harvest glyphosate on oat

Posted at 16:41h in Agronomy

Compared to direct combining without pre-harvest glyphosate, research found no effect on oat quality when glyphosate is applied at a seed moisture content at 40% or less. When applied at the recommended seed moisture content of 30%, pre-harvest glyphosate had a similar impact on oat...

10 Mar Impact of seed size and seeding depth on barley and oat production

Posted at 18:03h in Agronomy

Large seed and shallow seeding independently improved organic barley and oat production. In organic production, pre-seeding tillage is an important weed management strategy, however this can cause drier seeding conditions. To compensate, greater seeding depths are often used, which may reduce crop performance. A 2-year research project...

10 Mar Maximizing economic return in oats

Posted at 17:24h in Agronomy

A nitrogen fertilizer rate of 89 lbs. N/ac provided the most consistent economic returns when oat prices were between $2.50 and $3.00 per bushel. Fungicide application did not provide a benefit at any N application rate. In an effort to maximize yield and quality, some oat...

25 Jun Breeding for oat leaf blotch resistance

Posted at 17:11h in Disease

A 4-year research project at the University of Saskatchewan’s Crop Development Centre set the platform that will assist plant breeders in developing leaf blotch resistant oat varieties. Growing resistant varieties in combination with adequate crop rotation intervals will be the most effective, economical and eco-friendly...

29 May Large oat seed improves emergence, vigour and yield

Posted at 15:52h in Agronomy

Seeding large seeded oats improved early season oat biomass by 16% and 29% at two locations in eastern Saskatchewan. Large seeded oats also improved wild oat competition and resulted in 4 days earlier maturity. Yield was 8% higher at one site with large seed. Field trials...

30 Oct Improving tame oat competitiveness with wild oat

Posted at 14:58h in Weeds

Seed 35 seeds per square foot and apply at least 13.4 lbs. P205 per acre to improve wild oat competitiveness and increase tame oat yield. A three-year study was conducted at Agriculture and Agri-Food Canada Indian Head to determine if side-banded phosphorus (P) in combination with...
