AbstractTwo separate Upland cotton variety evaluations were conducted in southeastern Arizona during the 2006 cotton growing season. One location was in Graham County (Thatcher), while the second location was in Cochise County (Kansas Settlement). Sixteen varieties were planted at the Thatcher and ten varieties were selected and planted at the Kansas Settlement location. Varieties ranged in maturity from early to full at each of the locations. All plots were arranged in a randomized complete block design with four replications. Both locations were planted on grower-cooperator fields and were managed in accordance to the individual grower styles. Plant measurements were collected over the course of the season at only the Thatcher location. Lint yield was determined by harvesting the entire plot at each location and weighing the resultant seedcotton. Sub-samples were collected also at the time of harvest for percent lint estimates and fiber quality analysis. Crop value was calculated multiplying the lint yield by a lint price determined by a base value of $0.52/lb plus any discounts or premiums based upon fiber quality. Lint yield levels at both locations were high ranging from 1200 to just over 1900 lbs. lint/acre with a new Acala variety from Phytogen (PHY745WRF) producing the highest yield and also the highest crop value at the Thatcher location. In Kansas Settlement lint yields ranged from 1000 to over 1500 lbs. lint/acre with the highest lint yield and total crop value being produced again by the new Acala variety from Phytogen (PHY745WRF).
