Fight Weeds All Season Long Using These Tips for a Successful Burndown, Farm Record Keeping Made Simple with the FBN® App, How Does Your Farm Stack Up? Row spacing is more important than seeding rate for increasing Rhodes grass (Chloris gayana) control and grain yield in soybean (Glycine max).

A disease called “white mold” can be a problem. soybeans are generally planted by using split-row units placed between the 30-in. Choosing the right soybean row spacing and population is critical when it comes to maximizing soybean yields on your farm.
