SDSU Research Shows Effects Of Volunteer Corn In Corn And Soybeans
In 2007, researchers at South Dakota State University indicated that volunteer corn is much less competitive in corn than soybean. The South Dakota study (Alms et al. 2007) evaluated the full season effect of a range of volunteer corn densities (800-14,000 plants/acre) on both corn and soybean and reported yield losses that ranged from 0% to 13% in corn and 0% to 54% in soybean.
Drought Stress Symptoms in Soybean
Soybeans in South Dakota are in their moisture-critical reproductive stage. Drought stress during this growth stage can significantly impact yield, so here are some things to look for.
Woody Weeds: Tatarian Honeysuckle
Tatarian honeysuckle (Lonicera tatarica) was brought to North America from Asia in the mid-18th century for ornamental uses. In South Dakota it was also used as a windbreak species until the 1980s.
Multiple Rounds of Severe Weather Bring Heavy Rainfall, High Winds, and Soil Erosion
A combination of tillage, no residue, and lack of crop canopy can lead to severe erosion and topsoil loss in the face of extreme weather patterns in the spring. The most effective strategy for producers to adapt to these extreme events is to improve soil health.
Round Bale Storage Conservation

Flowering in Corn
Corn is at or near the most critical growth condition. Successful flowering and pollination are very important in determining the fate of the kernel setting and development. This article summarizes the pollination process and the effects of dry, hot conditions on pollination.
Check Fields for Palmer Amaranth
Palmer amaranth, is an aggressive weed from the pigweed family, which has been reported with increasing frequency in recent years around Central South Dakota.
Late Summer 2020 Climate Outlook
Drought concerns in South Dakota may be relieved later this summer, according to the NOAA Climate Prediction Center’s seasonal outlook released this week.
Peas Offer Options in 2020
Current events have made decisions around crop options very difficult this spring. Field peas are an option that may have a fit for some producers.
