Ultra narrow row (UNR) cotton has decreased production costs and increased yields in some areas. The UNR cotton is planted in 7.5- to 10-inch rows and is harvested with a finger-stripper because the row spacing is too narrow for a conventional spindle picker. This study investigated conventional and UNR cotton grown in 10 areas across the Midsouth and Southeast and ginned on a common gin for subsequent textile mill processing evaluation. The following gin machines were used for the UNR cotton: Separator-dropper, dryer, cylinder cleaner, stick machine, dryer, cylinder cleaner, Combination Bur and Stick (CBS) machine, cylinder cleaner, extractor-feeder and saw-type gin stand followed by two stages of saw-type lint cleaning. For the conventional cotton, the CBS machine and one of the stages of lint cleaning were not used. Initial foreign matter averaged 7.8 and 20.9%, for the conventional and UNR cottons; the UNR cotton had over 3 times more foreign matter than the conventional cotton initially. The marketing classifications, including foreign matter, were not statistically different. Ultra narrow cotton received barky calls on 1 of the 10 locations as compared to none for the conventional. Lint turnout differed dramatically for conventional and UNR cottons, and averaged 34.9 and 29.8%, respectively. About 245 more pounds of material were removed from the UNR cottons.
