Extension Crop and Pest Reports (Sept. 21-25)

Gary Lesoing

Extension Educator in Nemaha County

Harvest is beginning in earnest in southeast Nebraska. In traveling across Nemaha County and southeast Nebraska, there were a number of farmers harvesting, both corn and soybeans. Reports of excellent corn yields, with soybean yields more variable. Some soybean yields were reduced by the dry conditions in August and early September. The rains we received the second week of September benefited some of the later maturing soybeans. Corn yields on an on-farm research experiment in Nemaha County averaged over 200 bu/ac on a rainfed field.

The dry conditions continue in southwest Nebraska. Some early soybean harvest has begun, while other fields are still clinging to the last yellow leaves. Corn silage and cane harvest is progressing. Most cane hay looks to be done and baled already. Milo is ripening but still several weeks away from harvest. Some field edges have been harvested but are at a higher moisture. Wheat planting is beginning and a number planters are moving around the areas. I haven’t noticed as much volunteer wheat in fields this year, probably due to the dry conditions. Here is a photo from the sorghum test plots in Hitchcock county, the field was looking pretty good!

Soybean harvest is in full swing with irrigated beans drying down this week. I am hearing about irrigated yields from 70-90+ bu/ac and non-irrigated beans doing 40-60 bu/ac in spite of the hot, dry August. I am also hearing many comments about small soybean seed size. Seed corn harvest is about ¾ done and corn harvest is beginning with higher moisture corn. 

Woolly bear caterpillars in addition to stink bugs, grasshoppers, and loopers are present in soybean fields. Late season and/or later planted soybean fields should be scouted for insect defoliation and pod feeding. Hybrids vary in response to corn stalk rot with wind-damaged fields and plants that had ears droop prematurely succumbing at a higher rate. 

I am also seeing rye being drilled into newly harvested soybean fields which can help with weed control, erosion control, and provide grazing. Wheat planting will also occur this coming week.
