Trial Report Summary

Management Practices for High Yielding Spring Wheat

Crop Type(s):
Wheat
Centre(s):
PCDF
Year(s):
2018
Collaborators(s):

Anastasia Kubinec – Manager, Crop Industry Development, Manitoba Agriculture
Anne Kirk and Rejean Picard – Crop Industry Development, Manitoba Agriculture

Objective(s):

The objective of project is to quantify the yield benefit of intensive management practices in spring wheat, and to determine if these management practices provide the same benefit to a variety of cultivars.

Project Findings:

The result on the protein analysis will be available at a later date.  PCDF will post the link when it becomes available.

Background:

The focus of this project is on plant growth regulators (PGRs), fungicides, and higher nitrogen rates.

Targeting higher yields often means increasing nitrogen rates, which brings with it the increased risk of lodging.  PGRs are used to improve crop standability, and may be a good fit for a management system with increased nitrogen rates.  The PGR “Manipulator” (chlormequat chloride) is registered for use in Canada, but uptake has been limited due to the previous absence of an established maximum residue limit (MRL) for the USA.  This limit was set in April of 2018, marking a change in the management practices that are open to Manitoban wheat growers.

Fungicides to control fusarium head blight (FHB) and leaf diseases are commonly used on spring wheat in Manitoba.  Previous research has found some evidence of PGRs reducing protein content in spring wheat, but this is potentially not the case when PGRs are applied with fungicides.

The objective of this project is to quantify the yield benefit of intensive management practices in spring wheat, and to determine if these management practices provide the same benefit to a variety of cultivars.  This information will help producers make decisions on where to focus their input dollars, and will provide an opportunity to highlight the effects of PGR’s in spring wheat production.
