Methodology

This experimental field was in Lake County, South Dakota. Soybeans two different varieties were planted in 30-inch rows in strips on May 3, 2021. The purpose of this experiment is to compare two different varieties. This experiment had 2 replications for each variety. Soybean were harvested on September 26, 2021. For analysis purposes, the field was classified into three different yield zones: low yield zones (less than 35 bu/ac), mid yield zones (35-55 bu/ac), and high yield zones (more than 55 bu/ac). This analysis was performed for mid yield zone.

Results

Overall, there was no significant different in yield comparing two varieties (Figure 1 & Table 1). Variety 2 performed better comparing variety 1 however the increase in yield was not statistically significant. On average Variety 2 had 5.42 bu/ac increase in yield. More research at multiple sites with more replications are required to better explain the contrast between two different treatments in different environmental conditions.
