Reductions Of Wheat Yield And Yield Components And Nitrogen Loss Following Frozen Soil Nitrogen Applications, Carrie Ann Knott, Edwin L. Ritchey, Lloyd W. Murdock
Reductions Of Wheat Yield And Yield Components And Nitrogen Loss Following Frozen Soil Nitrogen Applications, Carrie Ann Knott, Edwin L. Ritchey, Lloyd W. Murdock
Plant and Soil Sciences Research Report
Most wheat producers in Kentucky apply nitrogen (N) as a split application. The first N increment is applied when wheat plants begin actively growing (green-up) in late winter, which is typically in mid- February between growth stages Feekes 2 to 3. The second N increment typically occurs in March when wheat is between Feekes 5 to 6. Many producers in Kentucky, especially Western Kentucky, have become accustomed to beginning first N applications in late January when the ground is frozen and the wheat is still dormant. This practice allows them to apply N to large acreages of wheat while avoiding …
Tillage And Subsoiling Effects On Soil Compaction And Yield Of Burley Tobacco, Edwin L. Ritchey, Robert C. Pearce, John H. Grove
Tillage And Subsoiling Effects On Soil Compaction And Yield Of Burley Tobacco, Edwin L. Ritchey, Robert C. Pearce, John H. Grove
Plant and Soil Sciences Research Report
Historically, tobacco producers have relied heavily on surface tillage to prepare fields for transplanting. This typically involved moldboard plowing, followed by several secondary tillage operations, such as discing then leveling with a soil finisher. Transplanter developments and modifications in the late 1990’s, coupled with new chemicals for weed control, made no-till (NT) tobacco a viable option for tobacco producers in Kentucky (KY).
