 |
Objective: Determination of the most profitable rotations for no-till production of winter wheat in central and western South Dakota | |
|
Duration: Present plans call for performing at least two rotation cycles (1991-2001) | |
|
|
Progress
Report/Accomplishments: The no-till rotation study is located on a half
section of land approximately 17 miles southeast of Ft. Pierre on and Opal-Promise soil
series. Research procedures utilize field scale equipment, weigh wagon yields, and
best management practices. Fifteen no-till rotations are included in the study and 1997 yields are as follows. Click on the corresponding number to view the crop inputs and machinery operations. |
