Pedersen: Shorting Your Growing Season is a Yield Limiting Variable
January 27, 2010 – 10:10 pm | No Comment
Assistant Professor, Soybean Extension Agronomist

Ever since I moved to Iowa in 2003 I have worked extensively on the importance of soybean growth and development and its correlation to yield. Through the soybean checkoff and the Iowa Soybean Association we have been able to address what it takes to raise high yielding soybean, and where we need to focus our research in the future to move the yield potential up even further. One thing that has been interesting to work on is the importance of early vegetative growth. Previously, we had never really paid much attention to what is happening prior to flowering, but that seems to be a mistake.

I do not believe that there are any farmers in Iowa that have not heard me talking about the importance of soybean planting date. And there is a reason. Soybean planting date is in some way our “soybean yield stimulus package”. By planting early we will stimulate the plant to achieve a higher yield potential. Unfortunately, we are not doing a good enough job. Our data shows that we need to be done planting soybean anywhere in Iowa by May 15 but based on USDA and the planting progress data over the last 5 years we often only have 50% of our acres planted by that day.

One of the major reasons why early planting is so important is we want to be sure the plant intercept as much solar radiation as possible since a soybean plant is a source limited plant. That means there is a close relationship between seasonal canopy photosynthesis and yield. So, by shorting our growing season we will reduce the yield. That is also why I do not recommend you to plant in 30 inch rows – the canopy closure takes too long time if there is some kind of a stress. Read the full story »
