Methodology

Treatment Information
Ascend® plant growth regulator, which contains which contains
kinetin, gibberellic acid, indole butyric acid, copper,
manganese, and zinc was applied at R3 on August 1 at 6.4 oz ac-1 to
the two treatment strips (Figure 1).

Agronomic and Weather Information
Soybeans with a 1.4 maturity rating were no-tilled into corn residue
in 15” rows on May 10 at 162,000 seeds ac-1. Seed was treated with
insecticide, fungicide, and a B. japonicum inoculant. The field
received approx. 8.95 in. of rain and accumulated 2595 GDDs from
June 1 through August 31. This was similar precipitation, but warmer
than the average of 9.15 in. and 1715 GDDs.

Results

Results
On average, this product appeared to decrease yields (Table 2), but
not at the 95% CI. With only two reps, statistical significance is very
difficult to achieve. Ascend has shown favorable results in previous
trials conducted at SDSU. Therefore, additional trials are needed to
help us better-understand when and where these types of responses
can be expected.
