Four Year Study of Corn Leaf Area
This study in eastern Colorado is an ongoing study dating from 2002 to the present. Leaf area is measured when corn has reached maximum height at 100 days after emergence. All leaves are measured excluding the leaf structures that encompass the ear of corn.
Our field measurements are compiled to allow growers to determine what are the effects of tillage management alternatives in relationship to corn leaf area in the Western Corn Belt. The first four groupings (left side) on the bar graph represent conventional tillage.
* This particular study defines conventional tillage as: 2 passes with a disc, 1 pass with a chisel, and 1 field finish operation prior to the planting operation. The second four groupings (right side) on the bar graph represent conventional tillage.
* This study defines strip-tillage as one pass prior to the planting operation.
