Research Projects

This project evaluated the impact of various corn, soya, and wheat fertilization methods on marketable yields, harvest quality, nitrate losses, and movement of microorganisms potentially pathogenic for humans.

This three-year project looked at optimal ways to use a mix of flowering plants against caterpillar pests of crucifers.

Biofumigation could be an attractive option for increasing the mortality of dormant seeds.

Managing potato residues is therefore a big challenge, which will only increase with the enforcement of the Québec Residual Materials Waste Management Policy.

Using a split-split-plot design, this study tested three variables: soil tillage, crop rotation in organic production, and fertilization with manure or compost.

The data generated by this project was used to develop a new NPK fertilization chart that reflects technical, agronomic, and environmental issues.

This project was aimed at determining the nutrient needs of beets based on soil texture and phosphorus and potassium levels under Québec growing conditions.

The aim of this project was to gather data on the nutritional requirements of barley to better equip producers, extension agents, and other industry stakeholders.

The aim of this project was to gather data on the nutritional requirements of oats to better equip producers, extension agents, and other industry stakeholders.

The aim of the project was to determine whether the witches’ broom symptom on blueberries is really caused by the rust Pucciniastrum geopertianum, which attacks balsam.

The fungal pathogen Helminthosporium solani causes silver scurf, a disease that is hard to detect, both in the soil and on harvested potatoes.

This project was set up to test the nutrient balance sheet method as a tool for estimating phosphorus output from pullets and laying hens.

To provide information on the fertilizing value and environmental impact of spreading pig manure at different times, the project compared the effect of mineral fertilizer in early fall, late fall, and in the spring.

This economic analysis measured the technical efficiency of Québec wild blueberry farms.

The aim of this project was to test the general hypothesis that exclusion nets, when properly used, can prevent attacks by most apple pests and reduce disease incidence with no major adverse effects on fruit quality.
