Abstract

Week three of the 2006 growing season began cool, but temperatures moderated by mid-week. The total degree-day accumulations for the week lagged slightly behind long-term average accumulations. The cool weather coupled with adverse seedbed conditions have combined to cause some crop emergence problems in scattered areas. Crops grow slower with cooler weather, taking longer to germinate and emerge, which challenges their vigor. Physical problems for the germinating and emerging plants include soil crusting, which physically interferes with emergence, and sidewall compaction that interferes with water uptake and secondary root establishment.
