Severe weather such as wind and hail forces a portion of Southern High Plains Cotton producers every year to make re-plant decisions. The objective of this study was to evaluate early maturity cotton varieties in a simulated re-plant situation.
2006: The design was a randomized complete block with 4 replications. The test was dry-planted on 13-June and watered up. Plots were harvested 28-November and weighed individually. Then a grab sample was taken for HVI fiber quality analysis. Per acre lint yields ranged from 1,014 lbs to 1,474 lbs, with the entire test averaging 1,294 lbs. (Ten inches irrigation + 9.76 inches rainfall from June to November produced 65 lbs lint yield per acre inch). Net value was calculated considering CCC loan value of lint, seed value, ginning costs, and seed/technology costs. The varieties with the highest net value per acre were All-Tex Excess RR and Phytogen 370 WR. Those with the lowest net value were All-Tex Xpress RR and Americot 1521 B2RF. The eight varieties in this test exhibited a net value difference of $314.54.
2005: The experimental design was a randomized block design with 3 replications. The varieties used in this test were Beltwide Cotton Genetics 50 R, All-Tex Xpress RR, All-Tex Excess RR, All-Tex Quickie, Fibermax 5045 BR, AFD 3511 RR, Paymaster 2145 RR, and Stoneville NG 1533 R. Plot size was 150 feet by two rows. The test was planted on June 13 on 40 inch rows and was irrigated with subsurface drip placed every forty inches under the bed.
Although Stoneville NG 1533 R and Fibermax 5045 BR had lower micronaire values, these varieties provided the highest gross return per acre with $640.62 and $630.11, respectively. All-Tex Quickie had the lowest gross return per acre with $476.63.
