Abstract

Rolling soybeans has become very popular in the past few growing seasons, especially in north central Iowa. Reasons for its popularity include, pushing rocks beneath the cutting height of bean heads, less dirt in the combine and cleaner beans, faster cutting speeds, less damage to cutting systems, and increased soybean yields. The last claim was studied at the Northwest Research Farm in 2009 and 2010 in both tilled and no-till conditions. Both tilled and no-till studies included a control treatment and rolling the soybeans pre-emerge and post-emerge when the beans were in the V1 stage of development. Soybean plots were rolled with a 20 ft Degelman Landroller from Custom Made Products in Humboldt, IA.
