However, the partitioning of shoot dry matter was not significantly affected by subsoiling (p [less than or equal to] 0.72), and there was not a significant interaction between surface and subsurface tillage treatments (p [less than or equal to] 0.19).
The effects of surface and subsurface tillage on shoot dry matter accumulations were similar to those found for grain yields (Table 6).
Neither surface tillage nor the surface tillage by subsurface tillage interaction was significant for grain N concentration.
* Use conservation tillage or subsurface tillage tools, such as rodweeders and subsurface sweeps, to leave crop residues on the soil surface.
Subsurface tillage tools that leave crop residues on the surface reduce this problem.
O'Leary showed that a stubble-retained no-tilled (SRNT) practice had greatest potential for groundwater recharge compared to subsurface tillage or conventional tillage practices.
CONVENTIONAL tillage utilizing moldboard plows or disks as primary tillage implements followed by shallow subsurface tillage with sweeps is the predominant method of weed control in the winter-wheat producing areas of eastern Wyoming.
