Research Projects

This two-year project, conducted at the Organic Agriculture Innovation Platform, compared the effect of three seeding dates and three seeding rates on chia yields.

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.

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.

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.

Canola and wheat (wheat-corn-canola rotation) were planted in 2016 and 2017, respectively, on 12 experimental plots with tillage practices on the main plots (minimum tillage and chisel plow) and fertilization methods (mineral fertilizers, 25 m³/ha of pig manure and 50 m³/ha of pig manure) in the subplots.

The purpose of this project was to study the vegetative propagation and regeneration capacity of Canada thistle and sow thistle with a view to developing effective weed control strategies.

IRDA—in its capacity as the authorized representative tasked with revising the MAPAQ fertilization reference charts—will plan, coordinate, and monitor all activities involved in updating these charts.

The goal of this project was to develop an “irrigation roadshow” for eight farming regions in Québec.

This project was aimed at identifying and incorporating biological indicators into decision support tools used to assist producers and agroenvironmental regulatory bodies seeking to preserve soil productivity and use sustainable production systems.

The project consists of evaluating soil degradation based on representative samples taken in Québec’s main soil regions and parent materials.

This project was aimed at evaluating the impact of integrated pest management on the profitability of field crop farms.

The project compared the nitrogen uptake effects of green manure crops grown for a full season, in association with a main crop, or after it is harvested.

The project was designed to assess the profitability of various types of cover crops and planting methods at the farm level.

The aim of the project was to estimate the economic impact of herbicide resistance in weeds.
