Replicated Dryland RACE Variety Demonstration,Floydada, TX - 2012Cooperator: Gary NixonMark Kelley, Chris Ashbrook, Ethan Fortenberry, and Dustin PatmanExtension Agronomist – Cotton, Extension Assistant – Cotton,CEA-ANR Floyd County, and EA-IPM Crosby/Floyd CountiesFloyd CountyObjective:The objective of this project was to compare agronomic characteristics, yields, ginturnout, fiber quality, and economic returns of transgenic cotton varieties underdryland production in the Texas High Plains.Materials and Methods:Varieties:Experimental design:Seeding rate:All-Tex Edge B2RF, Deltapine 1044B2RF, Deltapine 0912B2RF,Dyna-Gro 2400RF, FiberMax 9170B2F, NexGen 4111RF,PhytoGen 499WRF, and Stoneville 5458B2RFRandomized complete block with three (3) replications.2.3 seed/row-ft in 40 inch row spacings. (John Deere 1700 Vacuumplanter)Plot size: 8 rows by variable length (1320-1542)Planting date:Weed management:Rainfall:25-MayRoundup PowerMax was applied over-the-top at 28 oz/acre withAMS on 12-June and 2-July.Based on the nearest Texas Tech University – West TexasMesonet station at Floydada, rainfall amounts were:April: 0.31” August: 1.02”May: 0.63” September: 2.17”June: 2.26” October: 0.44”July: 0.12”Total rainfall: 6.95”112
