A cool, wet April has Illinois farmers behind in getting their corn crop in the ground. With nearly eight-inches of rain last month, farmers were only able to get one percent of the corn crop planted. That's far below the average of 43-percent planted by the end of April. The Illinois Department of Agriculture says last year, when April was dry and warm, 76-percent of the corn had been planted by this time. The state says even with the late start, the corn crop yield could be average or above.
