From Wet Weather To Dry Weather

 

 

 

 

Most areas in Ohio experienced above average rainfall during soybean vegetative stages.  With wet weather, soybeans tend to have reduced tap root growth and increased lateral root growth near the soil surface(photo example).  This is a problem when the weather turns dry...Dry areas in Ohio are reporting drought stress conditions on soybean such as soybean leaves flipping upside down.  August rainfall is very important as soybean seeds begin to fill.  (Soybean yield is determined by the number of plants, number of pods per plant, number of seeds per pod, and seed size).  On average, there are 2,500 individual soybean seeds per pound.  Soybean seeds produced during drought conditions and at high temperatures tend to be smaller than seeds produced under normal conditions.
