Frustrations have been expressed about the numbers of Japanese beetles and their soybean defoliation this season. This compounds the weather woes that soybean has endured, i.e., too wet, too dry, too hot, yellowing from nutrient deficiencies, and the herbicides seemingly torching them.

– Corn produces individual male and female flowers on the same plant.
– The ear represents the female flower of the corn plant.
– Severe soil moisture deficits can delay silk emergence and disrupt the synchrony of pollen shed and silk availability, resulting in poor kernel set.
Excessive rainfall and flooding often result in the loss of applied and soil-derived nitrogen (N).
Providing sufficient but not excessive nitrogen (N) to corn is difficult especially with fall and early spring fertilizer applications where N loss can vary substantially with the timing of the application relative to the occurrence of warm soil and excessive rainfall.
