Abstract:
... Canola ( Brassica napus L. and B. rapa L.) is an important cash crop in the Prairie Provinces of Canada. The majority of canola is grown in the Parkland zone where many soils are deficient or potentially deficient in plant-available S for optimum seed yield of canola. Because canola has high S requirements and S is immobile in plants, its deficiency can occur any time during the growing season and ...
