Impact of Field Rolling on Soybean Performance

Greg Endres and Bob Henson


Soybean plant damage from rolling.

A trial was conducted to determine the effect of timing of field rolling on soybean injury, stand, and yield. The trial was conducted on Heimdal loam soil with 3.4% organic matter. Experimental design was a randomized complete block with four replications. RG200RR was solid-seeded (7-inch rows) on May 27. A 3000 lbs., 15-ft wide, 18-inch diameter, 3-point hitch mounted Bison roller was used for field rolling during afternoons on a dry soil surface preemergence and during early emergence, cotyledon, and first trifoliate soybean growth stages (Table). The trial was harvested with a plot combine on October 1. Soybean plant injury increased as post-emergence rolling was delayed. Soybean stand, lodging, and yield were generally similar to the untreated check.  Plant moisture status (time of day, soil moisture content), location of plants in ridges/furrows, presence of surface residue, speed of rolling, and other factors may also influence plant tolerance to rolling.
