It is due to lack of pollination - probably too windy when pollination occurred. After the tassels have opened up run your hand up the tassel collecting the pollen and then rub on the silks of the cob. Do this when there is little wind in the morning. The pollen is microscopic. Try and plant in a spot that is protected from the wind a bit if you can.
