  7. 7. PREC Tillage Study ‘08-‘12There is no statistical yield difference between “Plow”and “Zone Till”There is a statistically significant decrease in yieldbetween… “Plow” and “No-Till” for all commodities except, Beansand 3 year corn following beans.… “Zone Till” and “No-Till” for all commodities exceptcorn in the 3 year rotation.

  15. 15. ConclusionsBased on the PREC Tillage Study Results: There is a difference in yield between “No-Till” andother tillage practices. Despite differences in yield “No-Till” Corn and DryBeans have a lower breakeven prices. “No-Till” Sugarbeets cost $4.90/ton more toproduce than “Plow” tillage.
