Methodology

Prairie Brand PP160 was no-tilled into soybean residue on 6/3/15 at 148,000 seeds with 3 gal 10-34-0 ac-1 in-furrow.  In addition to fungicide and insecticide, the seed was also treated with Bioboost+, an inoculant containing Delftia acidovorans and Bradyrhizobium.  A foliar application of 18-0-8 was applied at 2 gal ac1 on Jul. 30 at R3 to provide 4-0-2 lbs ac-1.  For increased crop safety, 72% of the N and 100% of the K2O were in the triazone and acetate forms, respectively.  The field received approx. 10.2” of rain from June 1 through August 31, accumulating 3.5” after the application.

Results

Yield differences within each treatment strip (Figure 1) were calculated by subtracting untreated yield from treated yield, where untreated yield was estimated from data surrounding both sides of the treatment strip.  However, a treatment where 10-0-2 lbs ac-1 were applied in the same field on the same day showed more potential.
