Soybean emergence in the cereal rye block was a couple days later than in the no-till block regardless of treatment. Final stand counts were similar for each block.
Soybean crop response from Valor® SX herbicide (i.e. leaf crinkling) was evident in the no-till block but absent in the cereal rye block.
Cereal rye suppressed the emergence and growth of small- and large-seeded broadleaf weeds compared to the no-till block (Table 2). Grass control was similar between the two blocks.
When averaged over all five treatments, utilizing a cereal rye cover crop resulted in an average 9 bu/acre yield advantage over no-till.
