A Look at CRP Land: Returning to Cotton Production

Joe Johnson, Keith McGregor, Seth Dabney


Producers need options for tillage production systems to use when Conservation Reserve Program (CRP) contracts expire. A study was conducted on the Brown Loam soils on North Misssissippi to evaluate production practices for cotton on land in sod managed similar to those in CRP. Tillage practices used for the trials were 1) Fall Hipped and rehipped the next spring; 2) Spring hipped and rehipped two weeks later; 3)Conventional tillage [disk, chisel, disk, hipped]; 4) No-till; 5)No-till+cultivate at four and eight weeks after planting. There was a 12% reduction in plant population for the plots that were planted no-till versus those that had at least one spring tillage. Plant were shorter and canopy closure later for the no-till planted plots. Weed population was higher at the end of the growing season for the no-till planted plots versus the plots that had a least one spring tillage.Residue levels were below 30% at planting for all the plots that had at least one spring tillage.
