Protecting Yield Potential from Heat and Drought Stress

Posted by Agricen

With many areas of the country in need of moisture, Agricen’s Scott Lay spoke with WITY Radio's Dennis Michelsen about Terramar, a new technology for the row crop market that can help growers protect their yield potential from heat and drought stress.

Dennis - WITY Radio: When it comes to wanting a little more rain and being concerned about stress in our corn and soybeans this time of year, that’s where Terramar comes into play.

Scott - Agricen: Right. Terramar is a new technology for the Midwest corn and soybean markets. We’ve already had it commercially available in high-value fruit and vegetable crops in Florida, California and the coastal areas.

Terramar is a combination of a biological extract of kelp and a carbon source that does two things. One, it helps to minimize effect of heat and drought stress in the plant. We’re trying to protect the yield potential that exists by minimizing yield robbing factors, like heat and drought stress, which are all too often an impediment to yield as the crop matures.

Three Ways to Combat Drought Stress in Corn

Posted by Agricen

Drought stress can cause significant corn yield reductions, particularly when it occurs after the V13 growth stage.

At V13 and beyond, drought stress can negatively impact silking, pollination, and kernel fill, with the greatest loss in yield associated with drought stress that occurs around the silking (R1) period. Drought stress causing four or more consecutive days of visible wilting during this period can lead to yield loss as high as 9 percent per day. Plants weakened by drought stress are also more susceptible to disease and insect damage, which can further compound yield losses.

What Options Do Corn Growers Have for Combating Drought Stress?

Although farmers can't control the weather, they do have options that can help them improve plant health and strengthen their crop's stress tolerance in the face of drought.
