The crop tolerance of red clover and weed control efficacy of fall-applied herbicides was evaluated in a field trial planted at Melfort, SK, spring 2017.

The aim of the trial was screening of six fall-applied products at 1X and 2X recommended rates of application and compare the application to an unsprayed control (check). The treatments were not replicated and yield data was not collected. However, the researchers at the Northeast Agriculture Research Foundation identified products with potential for use in seed production.

The following projects are in various stages of completion. Check back for updates on projects in our research section.

Although NARF has had an uncertain spring due to Covid-19 we have been able to get more trials in the ground then we would have ever anticipated with all the uncertainty in April/May.

Objective/Rationale: To evaluate the crop tolerance and weed control efficacy of spring-applied herbicides to Red clover, in support of registration under the Minor Use Program.

Objective/Rationale: To evaluate crop tolerance of Alsike clover and weed control efficacy of spring-applied herbicides in support of registration under the Minor Use Program.

Objective/Rationale: To evaluate crop tolerance and weed control efficacy of potential spring applied herbicides for use in established red clover, in support of registration under the Minor Use Program.

Northeast Saskatchewan is the centre of forage seed production in the province. Red clover is the largest forage seed crop after alfalfa. Alsike clover is also commonly grown for seed in the area. These clover crops, when harvested for seed, fit well into crop rotations.

Objectives: This project evaluates and demonstrates the use of direct seeding with the use of pre-seeding herbicide applications or pre-seeding cultivation when establishing forage seed crops.

Objectives: Controlling lesser clover leaf weevil has become an important operation in the production of red clover seed in Saskatchewan, yet producers are often unsure of proper timing of application.

Project Objectives: SFSDC wanted to determine if there are any residual effects of planting meadow bromegrass in alternate rows with wheat on seed yield of the forage in the second year of seed production.

Project Objectives: SFSDC wanted to demonstrate the importance of controlling Noxious and hard to control weeds such as cleavers and wild oats in established forage legume seed crops. The project used registered herbicides, including those registered under the minor use registration program, for weed control.

Project Objectives: SFSDC wanted to demonstrate the effectiveness of using alternate row companion crop planting when establishing forage seed crops. The project demonstrated the agronomic and economic advantages of alternate row planting using presently available equipment technology.

Project Objectives: Reglone is the only registered desiccant for use on red clover seed production. It typically takes longer than anticipated to dry down the crop enough for harvest.

Project Objectives: SFSDC wanted to demonstrate the effectiveness of using alternate row companion crop planting when establishing forage seed crops. The project demonstrated the agronomic and economic advantages of alternate row planting using presently available equipment technology.

In June 2013, we applied foliar EDTA chelated copper to established timothy (3 locations) and hybrid bromegrass (1 location) on replicated mini-plots. This was repeated in June of 2014 and June 2015, but we added 2 other liquid Cu foliar treatments; dropped one unresponsive site and added another potentially responsive hybrid bromegrass site.

Enhanced efficiency fertilizers (EEFs) are intended to reduce nutrient losses to the environment, thereby increasing nutrient availability for plant production. One category of EEFs is nitrogen (N) fertilizer that is stabilized using compounds such as urease and nitrification inhibitors, both of which slow the release of N by controlling key microbially mediated processes.

Weed control is critical in the establishment year for forages grown for seed production. With that in mind we initiated a research trial to identify herbicide options that provide adequate weed control while posing acceptable risk of crop damage for selected forage species where suitable weed control treatments do not currently exist.

No studies have been conducted to determine forage seed yield response to N and P fertilizers as affected by the availability of these elements in northeastern Saskatchewan soils.

Objective: To determine the efficacy of the insecticides Cygon, Decis and Sevin XLR for the control of lesser clover leaf weevil in established red clover.
