Corn plants for most of Minnesota have been short of moisture or under high temperature stress for the past four weeks. Since most fields are past tasseling and silking, one can now determine the success of the pollination and fertilization process. The objective here is to describe a simple method to determine the fertilization success and to discuss the effect of stress on plant recovery and grain yield.
