In July 2022, hybrid bromegrass (HBG) AC Success was seeded at Melfort, SK. Three different fertilizer sources of urea with urease and nitrification inhibitors were demonstrated, each applied at three different times (early fall, late fall and early spring).

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.

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.

Chapter 1: Efficacy and mechanisms of communication disruption of the red clover casebearer moth (Coleophora deauratella) with attractive and unattractive pheromone formulations.

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.

Objective: To determine the tolerance of established red clover to a number of post-emergence herbicides. Three studies were conducted in the Arborfield – Carrot River; however, seed yields were obtained only at the two Arborfield sites.

Invasive plant species are non-native plants introduced outside of their natural habitats. In this new environment, free from their natural ‘enemies’, they have an advantage that allows them to out-compete native plants and agricultural crops for space, moisture and nutrients.

Become familiar with plant identification and control strategies. Inspect pastures, holding pens, corrals, trails, salting locations, watering sites, and fireguards regularly. Inspect and clean vehicles, including undercarriage, prior to entering or leaving pastures. Ensure that feed sources are weed-free.

Become familiar with plant identification and control strategies. Inspect fields and surrounding areas regularly to identify plants posing potential risk. Inspect and clean equipment and vehicles regularly. Develop a written biosecurity protocol for bringing in new equipment, seed or feed.

In the Canadian Prairie Provinces, nitrogen (N) and phosphorus (P) are most commonly deficient nutrients, while potassium (K) and sulphur (S) may also be deficient for certain crop and soil conditions. One or more of these four major nutrients may be limiting for optimum forage seed production.
