Field experiments were conducted at Fort Vermilion and Beaverlodge, Alberta, and at Melfort and Tisdale, Saskatchewan to determine the effect of direct seeding on nodulation of field pea. There was significant reduction in soil temperatures and an increase in nodule numbers and weight under direct seeding at Fort Vermilion. Nodulation was also enhanced at Melfort and Tisdale. However, the enhanced nodulation did not always translate into increased grain yield. In no case was nodulation reduced with direct seeding. Soil temperature under reduced tillage systems does not appear to be a limiting factor in nodulation of field pea.
