TEXAS PANHANDLE COTTON VARIETY TRIALS
Mark Kelley, Texas AgriLife Extension Service
Characteristics commonly evaluated in small-plot testing include lint yield, turnout percentages, fiber quality, and earliness. Current small-plot variety testing programs are inadequate in scale and design to investigate the economic impact of new transgenic varieties with value-added traits. The objective of this project was to evaluate the profitability of cotton varieties in producer fields in the Texas Panhandle. For scientific validity, three replications of each variety were included at each of four locations. Trials were conducted under irrigation in Sunray, Dumas, White Deer, and Pampa. Plot weights were determined at harvest using a flat-bed scale trailer and bur cotton yields were subsequently calculated by plot. Grab samples were taken from each plot for ginning and fiber quality. Due to extremely high and extraordinary leaf and color grades from grab samples, leaf and color grades were set at 3 and 21, respectively at all locations.
In 2012 cotton yields were outstanding in spite of the continued drought across most of the Texas High Plains and Northern Panhandle Regions. All locations were well maintained by the cooperating producers. Also, these locations were subjected to an early freeze event on 8-October and contributed to lower than expected micronaire values. At Sunray lint yields ranged from a high of 2225 lb/acre for FiberMax 9058F to a low of 1510 lb/acre for PhytoGen 367WRF. Loan values ranged from $0.5342 for NexGen 1551RF to $0.4677 for Deltapine 1219B2RF. When subtracting ginning and seed/technology costs from total value (lint value + seed value), net values ranged from a high of $1,182.32/acre for FiberMax 9058F to a low of $756.36/acre for Deltapine 1219B2RF. At the Dumas location lint yields ranging from 1702 lb/acre (Deltapine 104B2RF) to 929 lb/acre (NexGen 1551RF), were observed. Loan values ranged from a high of $0.5723 for Deltapine 1212B2RF to a low of $0.5357 for NexGen 1551RF. This resulted in net values with a range of from $1045.54/acre for Deltapine 104B2RF to $531.73/acre for NexGen 1551RF. At White Deer lint yields averaged 1725 lb/acre and Deltapine 104B2RF had the highest with 1932 lb/acre. Loan values ranged from $0.5710 for NexGen 1551RF to $0.4765 for Deltapine 1219B2RF. Final net values ranged from a high of $1,129.83/acre (Deltapine 104B2RF) to a low of $729.84/acre (Deltapine 1219B2RF). At the Pampa location lint yields ranging from 1509 lb/acre (FiberMax 2011GT) to 1008 lb/acre (NexGen 1551RF) were observed. Loan values ranged from a high of $0.5730 for Deltapine 104B2RF to a low of $0.5380 for NexGen 1551RF. Resulting in net values with a range of from $909.80/acre for FiberMax 2011GT to $577.90/acre for NexGen 1551RF.
These data indicate that substantial differences can be observed in terms of net value/acre due to variety and technology selection. The differences in net value/acre, when comparing the top and bottom varieties at the Texas Panhandle locations, differences were approximately $432 (Sunray), $513 (Dumas), $400 (White Deer), and $332 (Pampa). Additional multi-site and multi-year applied research is needed to evaluate varieties across a series of environments.
