Methodology

Prairie Brand PP120 was no-tilled into corn residue on 6/10/15 at 148,000 seeds with 3 gal 10-34-0 in-furrow ac-1.  In addition to fungicide and insecticide, the seed was also treated with Bioboost+, an inoculant containing Delftia acidovorans and Bradyrhizobium.  A foliar application of 28-0-0 was applied to the three treatment strips at 2 gal ac1 on Aug 12 at R3 to provide 6-0-0 lbs ac-1, with 72% of that N in the triazone form for increased crop safety.  The field received approx. 10.2 in. of rain from June 1 through August 31, accumulating 1.6” 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.  Overall, the fertilizer application did not significantly increase yields (Table 2).  However, within the same field on the same date, an application of 10-0-2 lbs ac-1 showed more potential.
