Abstract
Several new canola varieties have much higher yield potential than those grown in the past. For example, the yield potential of highest yielding varieties listed in the Varieties of Grain Crops booklet for 2001, published by Saskatchewan Agriculture and Food are as much as 35% greater than for the check variety AC Excel. One question that arises is whether such varieties require greater inputs of fertilizer nutrients, particularly nitrogen (N), to realize optimum economic returns.
