Effect of irrigation regimes on weed control in organic cranberry production

-A +A
Travail de recherche

Projet financé par Agriculture et Agroalimentaire Canada dans le cadre de la grappe scientifique biologique II.

The American Cranberry (Vaccinium macrocarpon Ait.) is one of three berries native to North America. Canada, particularly Quebec, is the leading producer of organic cranberries in the world. One of the major issues that compromises organic cranberry production is weed management.

The purpose of this activity is to test the effect of optimized irrigation regimes on weed suppression in a cranberry field under establishment and in a field in production. The proposed optimized irrigation regimes in this activity consider soil-moisture tension, canopy temperature and the amount of water needed by the cranberry crop to form roots during establishment. The recovery rate of the cranberry and the recovery rate of the weeds will be compared in the different study plots. The identification of weed species based on irrigation regime will be carried out. Cranberry yield based on fruiting will be estimated once the crop is established.

At the end of the activity, recommendations will be made regarding the effect of irrigation management on weed suppression and an innovative, effective solution could be proposed to farm businesses for weed suppression in cranberry crops.
