Potential Causes of Poor Soybean Emergence in Cool Wet Soils

Potential Causes of Poor Soybean Emergence in Cool Wet Soils


Hi, I’m Damon Smith, Extension Field Crops
Pathologist for the University of Wisconsin Madison. Today, we’re in a soybean field looking at
different planting populations. One thing to consider early on when you’re
planting your soybeans is the planting population that you’re gonna go at, and also, early season
disease management. Diseases such as pithium can cause seed rot
issues and poor emergence. In those cases, when you’re planting into
cool, wet soils, you’re gonna want to plant more seeds per acre, especially if you don’t
have a seed treatment. You’ll see here in this particular section
of the field, we do have poor emergence. Probably due to both pythium seed rot and
also crusting that we have in the field after we had a hard rain on top of this particular
stand after planting. In a situation like this where we’re planting
into cool, wet soil, we definitely want to consider the disease potential here. Things like pythium here in Wisconsin can
be a problem early on in the season. If we don’t have a seed treatment, we would
want to plant at a population higher than 140,000 seeds per acre. With a seed treatment, our target planting
population would be about 140,000 seeds per acre to achieve an acceptable stand. For more information about seedling rots of
soybean, or early season diseases of soybean, feel free to visit the links at the bottom
