Replicated LEPA Supplemental (Limited) Irrigation Cotton Variety Research Trial -2012Cooperator: Cheuvront FarmsManda Anderson, Extension Agent - IPMDr. Mark Kelley, Extension Agronomist - CottonGaines CountySummary:Objective:Significant differences were observed for all yield, economic, and some HVI fiberquality parameters measured. Lint turnout ranged from a low of 30.9% and ahigh of 36.2% for All-Tex Nitro-44 B2RF and Phytogen 499WRF, respectively.Lint yield varied with a low of 258 lb/acre (FiberMax 2989GLB2) and a high of326 lb/acre (PhytoGen 499WRF). Lint loan values ranged from a low of$0.4738/lb (FiberMax 2989GLB2) to a high of $0.5355/lb (All-Tex Nitro-44B2RF). Net value/acre among varieties ranged from a high of $134.62(PhytoGen 499WRF) to a low of $81.71 (FiberMax 2989GLB2), a difference of$52.91. Micronaire values ranged from a low of 4.2 for All-Tex Nitro-44 B2RF toa high of 4.9 for FiberMax 2989GLB2. Staple averaged 32.4 across all varietieswith a low of 30.6 for FiberMax 2989GLB2 and a high of 33.7 for All-Tex Nitro-44B2RF. Strength values averaged 27.7 g/tex with a high of 30.5 g/tex for All-TexNitro-44 B2RF and a low of 24.1 g/tex for FiberMax 2989GLB2. These dataindicate that differences can be obtained in terms of net value/acre due to varietyand technology selection.The objective of this project was to compare agronomic characteristics, yields,gin turnout, fiber quality, and economic returns of transgenic cotton variety undersupplemental irrigated production in Gaines County.Materials and Methods:Varieties:All-Tex Nitro-44 B2RF, Deltapine 1044B2RF, FiberMax 2484B2F, FiberMax2989GLB2, NexGen 1511B2RF, PhytoGen 499WRF89
Experimental design: Randomized complete block with 3 replicationsSeeding rate:Plot size:Planting date:Soil Texture:Irrigation:Harvest:Gin Turnout:Fiber Analysis:Ginning cost andseed values:Seed andtechnology fees:3 seeds/row-ft in 36-inch row spacing6 rows by variable length of field (712ft to 1744ft long)17-MaySandyThis location was under a LEPA center pivot. This trial receivedapproximately 9.1 inches of irrigation and rainfall throughout the growingseason.Plots were harvested on 22-October using a commercial stripperharvester. Harvest material was transferred into a weigh wagon withintegral electronic scales to determine individual plot weights. Plot yieldswere adjusted to lb/acre.Grab samples were taken by plot and ginned at the Texas A&M AgriLifeResearch and Extension Center at Lubbock to determine gin turnouts.Lint samples were submitted to the Fiber and Biopolymer ResearchInstitute at Texas Tech University for HVI analysis, and USDA CommodityCredit Corporation (CCC) Loan values were determined for each varietyby plot.Ginning costs were based on $3.00 per cwt. of bur cotton and seedvalue/acre was based on $250/ton. Ginning costs did not includecheckoff.Seed and technology costs were calculated using the appropriate seedingrate (3 seed/row-ft) for the 36 row spacing and entries using the onlinePlains Cotton Growers Seed Cost Comparison Worksheet available at:http://www.plainscotton.org/Seed/PCGseed12.xlsResults and Discussion:Significant differences were observed for all yield, economic, and some HVI fiberquality parameters measured (Tables 1 and 2). Lint turnout ranged from a lowof 30.9% and a high of 36.2% for All-Tex Nitro-44 B2RF and Phytogen 499WRF,respectively. Seed turnout ranged from a high of 49.6% for FiberMax 2989GLB2to a low of 46.5% for Deltapine 1044B2RF. Bur cotton yields averaged 863lb/acre with a high of 911 lb/acre for All-Tex Nitro-44 B2RF, and a low of 75490
