Cotton is a multi-purpose crop that is harvested for fiber, feed, and as a food crop.
The cottonseed is crushed and turned into three products: oil, meal, and hulls.
Through research and cooperation with other
universities and specialists, OSU’s Department of Plant and Soil Sciences has created and compiled resources with the intent of helping producers have an efficient and successful harvesting season.
Improper handling of seed cotton may impact profits for producers and ginners. Inclement weather and increased moisture may reduce the color grade and cause rot.

The utilization of the small grain, whether intended as a cover crop, for grazing or forage and/or food use, may impact the cotton harvest aid use rate or plant back restriction to specific types of small grains. The best management option is to determine the end use of the small grain prior to selecting harvest aid products, as some products will eliminate some end use options for the small grain.

The classification system for Upland cotton consists of classer leaf grade and extraneous
matter (if any) and instrument measurements for color grade, fiber length, micronaire,
strength, length uniformity index, color Rd, color +b, and trash percent area. All
measurements currently utilized in USDA Upland cotton classification are from Uster High Volume Instrument (HVI)* systems.
