Arizona Upland Cotton Variety Testing Program, 2002

Each year the University of Arizona conducts variety trials across the state to evaluate the performance of Upland cotton varieties. These tests provide unbiased data on the performance of varieties when tested side-by-side under typical production practices. In 2003, a total of 11 trials were planted. Two in the Yuma region (Yuma County), two in the western region (La Paz and Mohave counties), four in the central region (Maricopa and Pinal counties), one in the southern region (Pima county), and two in the eastern region (Graham, Greenlee, and Cochise counties). We tested eight to fourteen commercially available varieties at each test site. This article presents the results of the 2003 variety tests conducted at each location.
