Why should you rush to plant your 2012 soybeans early? According to Dr. James Specht, a University of Nebraska researcher, the following list is why you should plant soybeans early:
To capture more seasonally available solar radiation (sunlight)
To transpire a greater fraction of the seasonally available water
More nodes – after V1, a new node develops every 3.7 days
These three factors (1-3) give to us the opportunity to increase soybean yields for no additional out-of-pocket expense.
