Evaluating Yield Potential and Yield Loss

Published on Wednesday, August 31, 2016

What a year it has been. Many areas have experienced both hot and cold temperatures, as well as wet and dry spells. As we evaluate the crop in August, we have a great opportunity to take a hard look at yield potential and yield loss suffered this year. Walk your corn fields, pull ears and check for pollination problems. If there are some, think back to pollination time. Was it dry, wet, hot, or cold? If you lost a lot of nitrogen early, ears could be stunted. We saw some early disease pressure in corn as well. How well are your hybrids holding up? If certain hybrids have more pressure than others, talk to your seed advisor about fungicide next year. We had insect feeding from armyworm and corn borer in July, do you have damage? This may affect which fields you harvest first.

Rains in August can make great soybeans. Walk your soybean fields to look for diseases and insects. Sudden Death Syndrome (SDS) could be common this time of the year. If you see feeding on pods, an insecticide application may be necessary. Also, look at weed pressure. If you have a lot of escapes from your glyphosate program, think about moving to a LibertyLink® program or using residuals. I hope to see all of you at Becknology™ Days!
