Dyna-Gro CT 12222B2RF (tested as DG 11R110B2RF)Location 3: White Deer, TX – Carson CountyTwelve varieties were planted to 30” no-till rows on 19-May with an approximate seeding rate of72,000 seed per acre. Plot sizes were 8 rows wide by 800 feet. Harvest was conducted usingthe producer/cooperator harvesting equipment and the flat-bed scale system. Gin turnouts, HVIfiber quality and CCC lint loan values were determined from grab samples taken at harvest.Varieties planted at White Deer (No-Till LESA irrigation system):1. FiberMax 2011GT2.

All-Tex Edge B2RFLocation 4: Pampa, TX – Gray CountyAt the Pampa location, twelve varieties were planted to 30” strip-till rows on 17-May with aseeding rate of approximately 64,000 seed per acre. This location was under a Low ElevationSpray Application (LESA) center pivot irrigation system. Plot size was 8 rows wide by 800 feetlong. Plots were harvested using producer/cooperator equipment and grab samples were takenby plot and ginned at the Texas A&M AgriLife Research and Extension Center at Lubbock.Resulting lint samples were submitted to the Texas Tech University – Fiber and BiopolymerResearch Institute for HVI fiber analysis and CCC loan values were calculated.97

All-Tex Edge B2RFResultsAgronomic and economic results by variety for all locations are included in tables 1 - 8.Location 1 - SunrayAt the Sunray location, lint turnouts of field-cleaned bur cotton averaged 32.5% (Table1). Bur cotton yields averaged 5447 lb/acre and no significant differences were observedamong varieties. Lint yields ranged from a high of 2225 lb/acre for FiberMax 9058F to alow of 1510 lb/acre for PhytoGen 367WRF, and seed yields averaged 2625 lb/acre.Loan values derived from grab samples ranged from $0.5342 for NexGen 1551RF to$0.4677 for Deltapine 1219B2RF. After applying loan values to lint yields, the testaverage lint value was $861.03/acre. When subtracting ginning and seed/technologycosts from total value (lint value + seed value) net value averaged $935.18/acre acrossvarieties. Net values ranged from a high of $1,182.32/acre for FiberMax 9058F to a lowof $756.36/acre for Deltapine 1219B2RF. Four other varieties were in the statisticalupper tier with FiberMax 9058F, FiberMax 2011GT ($1,119.83/acre), NexGen2051B2RF ($1,080.88/acre), FiberMax 9250GL ($1,028.38/acre), and Deltapine104B2RF ($1,023.98/acre).Classing data from grab samples are reported in Table 2. Micronaire values wererelatively low at Sunray due to the abbreviated growing season experienced in 2012.Values ranged from a high of 3.3 for NexGen 1551RF to a low of 2.4 for Deltapine1219B2RF. Staple was highest for FiberMax 9180B2F (38.3) and lowest for NexGen1551RF (35.3). The highest uniformity, 81.1%, was observed in FiberMax 9180B2F andFiberMax 9250GL had the lowest with 77.5%. Fiber strength values ranged from a highof 33.3 g/tex for FiberMax 9180B2F to a low of 28.7 g/tex for NexGen 2051B2RF.98
