Rupturing the tillage pan with a chisel and planting directly over the chisel mark increased dry pea yields by as much as 50%. Chiseling and not rupturing the pan depressed yields. Root disease was not influenced by chisel tillage. T: Pea yield with and without chisel treatments. Pea root disease index. Soil water status as influenced by chisel tillage.

Silt loam soils in the Pacific Northwest which had been cropped for over 20 years to a wheat-pea rotation had soil hard pans below the tillage layer at 20 to 35 cm.
