It looks like Colby split the shuck during the first week of September (photo at right).
It may be hard to see in this photo but you there is a slight crack in the green hull were the shuck has split along the raised suture of this James pecan (photo at left).
Norton was fully ripe this week. The shuck is still holding onto the pecan but all four sutures on every nut are split open (photo at right).
Peruque usually ripens during the last week of September at the Pecan Experiment Field. However, as of September 11 our Peruque crop is full mature (photo at left).
