Results and Discussion:Significant differences were noted for lint turnout and net value (Table 1). Lintturnout averaged 22.2% with a high of 23.8% and low of 20.4% for Deltapine1044B2RF and Stoneville 5458B2RF, respectively. After subtracting ginning,seed costs and technology fees, the net value/acre among varieties ranged from ahigh of $94.44/acre (Deltapine 1044B2RF) to a low of $63.50/acre (Phytogen375WRF), a difference of $30.94.Significant differences were observed among varieties for micronaire, elongation,leaf, and reflectance (Table 2). Micronaire values ranged from a low of 3.0 forStoneville 5458B2RF to a high of 3.9 for All-Tex Epic RF. Elongation averaged7.0% across varieties with a high of 7.8% for Phytogen 499WRF and a low of 6.3%for Stoneville 5458B2RF. Color grade components of Rd (reflectance) and +b(yellowness) averaged 80.4 and 8.5, respectively.These data indicate that differences can be obtained in terms of net value/acre dueto variety selection. Additional multi-site and multi-year applied research isneeded to evaluate varieties across a series of environments.Acknowledgments:Appreciation is expressed to Cody Walters for the use of his land, equipment andlabor for this demonstration..Disclaimer Clause:Trade names of commercial products used in this report are included only forbetter understanding and clarity.
