The results of seven years of research conducted mainly on the Gold Rush and Russet Burbank cultivars at IRDA’s Deschambault station demonstrated the impact of sound irrigation management on the rate of nitrogen use by potatoes and reinforced the link between nitrogen rates and marketable yield. However, this data was generated mainly with a single cultivar under experimental conditions and over multiple years with variable soil and climatic conditions, which produced considerable variability in the data. It was important, therefore, to measure the impact of irrigation management on nitrogen uptake and available soil nitrogen during the season under commercial production conditions at the same place and on several cultivars at the same time and to link this impact to total and marketable yields and post-harvest residual nitrate.

Aerial spraying to optimize the release of trichogramma wasps in order to control the European corn borer over large areas of sweet corn crops in Québec.
There is a great need to test green manure as a main source of nitrogen for potatoes as they help to maintain soil quality and control weeds.
