- Abstract/Summary: Trials were established at Yorkton, Indian Head, Swift Current, Scott, Melfort, Prince Albert, and Redvers to determine if delaying the crop’s access to nitrogen could decrease lodging, increase protein, and maintain test weight and yield of milling oat. Applying a portion of the total N as dribble banded UAN (4 leaf vs boot stages) or side banded ESN was compared to side banding all the N as urea. These comparisons were made at total N levels of 110 and 140 lb/ac (soil + fertilizer). Some benefits from managing N were detected, however, they were rare and inconsistent. While yield and protein did not typically differ between levels of N management at most sites, applying a portion of the total N as UAN at the boot stage decreased both yield and grain protein at Indian Head. This highlights the environmental risks associated with split applications. However, there were a couple instances where supplying a portion of the N as ESN or dribble banded UAN did increase grain protein by providing late season N to the crop. Levels of lodging were very low at most locations, making it difficult to detect any differences between N management. However, even at sites where lodging was high, no significant effects were detected. Maintaining oat test weight with UAN at the boot with the use of ESN was detected in a couple of instances at Swift Current. However, these effects were not detected at any of the other locations despite test weight being responsive to added N at 4 of the locations. In conclusion, there was limited evidence that applying a portion of the N requirement as ESN or dribble banded UAN could maintain yield and test weight, increase grain protein, or reduce lodging. Effects were inconsistent between sites and even between levels of total N within a site.

Abstract/Summary:
Principal Investigator Dr. Randy Kucher led the project, which was undertaken by student Jessa Robb. This oat nursery project entailed two parts:
Evaluation of up to 10 oats cultivars for susceptibility or resistance to bacterial leaf streak (BLS), caused by Xanthomonas translucens.
Using one cultivar of oat, the pathogen will be applied to the whole trial. Two treatments will be applied and compared: (1) only water [no bactericide] and (2) CuS04 (formulated as Bordeaux mixture).
This project was funded by the Saskatchewan Oat Development Commission (SaskOats).

- Abstract/Summary: Herbicide resistance of tough to control weeds, such as kochia and wild oats, is an ongoing problem on the Canadian Prairies. Herbicide resistance surveys conducted over the last two decades on the Prairies continue to demonstrate the increasing prevalence of herbicide-resistant weeds. With increasing incidence of herbicide resistance, utilization of different herbicide groups for control of resistant types is essential to ensure farmers don’t lose crop yield to weed pressure. Herbicide resistant weeds cost farmers a significant loss in income every year, at an estimated $340 million in Saskatchewan alone.

Abstract/Summary:
In Canada, kochia can now exhibit resistance to up to five herbicide modes of action (including Groups 2, 4, 5 (in the USA), 9, and now, 14). Very few herbicide options remain to control multiple herbicide-resistant kochia, and the ones that are available have rather limited use cases.
This project aims to understand which of the remaining herbicide options are available, especially before crop planting, and what approach can lead to better stewardship of these remaining active ingredients to mitigate further selection for resistance to new modes of action.
Objectives (note: wherever PPO-inhibitor-resistant kochia is mentioned, this refers to Group 14 resistance):
1. Determine cross-resistance to PPO-inhibiting herbicides in PPO-inhibitor-resistant kochia confirmed in SK.
2. Determine cross- or multiple-resistance to other herbicide modes of action in PPO-inhibitor-resistant kochia.
3. Determine the mechanism conferring resistance to PPO-inhibiting herbicides in kochia.
4. Continue monitoring kochia survey samples for PPO-inhibitor resistance across the Canadian Prairies.
5. Assess efficacy of alternative herbicides to manage multiple herbicide-resistant kochia prior to crop seeding.
6. Determine the mid/long-term utility and sustainability of strategic tillage for kochia management.
7. Assess the impact of timing and implement/depth of soil disturbance on kochia emergence, density, and the soil seedbank.
8. Determine the mid/long-term impact of winter cereals and perennials in crop rotations on multiple herbicide-resistant kochia.

- Principal Investigators: Brianne McInnes, NARF
- Project Dates: 2024-2025
- Abstract/Summary: The main objective for this project was to demonstrate the yield and quality response of new milling oat varieties to enhanced fertility as compared to a commonly grown and accepted variety.

- Project Status: In Progress
- Principal Investigators: Dr. Linda Gorim, University of Alberta
- Project Dates: 2024-2027
- Abstract/Summary: The overall objective of this three-year project is to assess the interaction between PGRs, increased seeding rates and shattering in tall and short oats varieties. Both PGRs (listed below) have been registered for cereals but recent research (on barley) has demonstrated that only Moddus® is effective in barley. Therefore, it is important to assess the effect of both PGRs on oats. Oat varieties that will be evaluated are: AC Morgan and CDC Arborg (tall varieties); and, CS Camden and Summit (short varieties). POGA will update producers on the progress of this research as annual status and final reports are received.

Abstract/Summary:
Project Lead Dr. Jaswinder Singh (McGill Department of Plant Science) is working with collaborators Dr. Nick Tinker, Wubishet Bekele, Kirby Nilsen, and Jean-Sebastien Parent.
The objectives of this project are:
Identification of regulatory sequences in the identified gene/chromosome region, and refining of gene editing in oat.
Development of specific CRISPR constructs.
Transformation of the said constructs into oat for developing mutant lines.
Genotypic and phenotypic screening of oat mutant lines.
This work could help zero in on problems faced by Prairie oat growers. Oats grow well on the Canadian prairies, but even varieties that flower and mature early can be susceptible to lower yield and disease risk. If CRISPR modifications can produce reliable DNA editing that can predict the influence on all traits, then in the future oat breeders* could engineer superior germplasm by modifying a single specific gene that would help producers harness the crop's biological potential. *Note: If there is a desire by both producers and oat buyers for use of the technology in oats.
