The breakdown
What happened, measurement by measurement.
Every chart below is transcribed from the report you can open above. Green means the AgriTec program won the measure outright; grey means it came in statistically even, which on a quality measure is the result you want — the yield came without a give-back.
Harvested weight per plot
Full-rate Bio-Act carried the most weight off the plot.
Test weight
Quality held across both rates.
Stand at 14 days
Near-complete emergence on every treatment.
Everything else that was measured
Including the measurements that did not move. A trial that only reports what improved isn't a trial.
Harvested weight per plot
12.11 a / 11.24 b / 11.79 ab lb
P(F) = 0.022 · LSD 0.55 lb · +0.88 lb/plot for the full rate
Stand at 14 days
137,940 to 139,392 plants/ac
P = 0.14 · not significant · 98 to 99.6% of the seeding rate emerged
Moisture

What the report says
- Bio-Act rate paid. Moving from 32 to 85 fl oz per application, and adding the at-plant broadcast pass, was worth 4.0 bu/ac.
- The gain showed up on the scales: treatment 1 was the only one significantly heavier per plot, 12.11 vs 11.24 lb.
- Adding 3 gal/ac of Nitro-Maxx+ at R5 to R6 recovered +2.6 bu/ac on the reduced-rate program, though not statistically separable from either other program.
- Emergence was uniform at 137,900 to 139,400 plants/ac, so the yield difference came after the stand was set.
- Treatment 1 applied four times the total Bio-Act of the reduced programs, 255 vs 64 fl oz/ac.
Trial notes & scope
- There was no untreated check. All three treatments are AgriTec programs sharing the same Pro-Cal + 3-18-18 base, so the +4.0 bu/ac is full-rate vs reduced-rate Bio-Act, not vs untreated ground.
- Treatment 3 was not statistically separable from either treatment 1 or treatment 2.
- One year, one site. Pair these results with your own soil test before setting rates.
- Stand, moisture and test weight showed no treatment effect.
- The report prints two harvest dates: November 29 in the header and timeline, November 22 in a results heading.
