Cotton planting date effects in the U.S. Southern High Plains (SHP) were evaluated based on 11 years of May-planted and June-planted irrigated variety trials. Multiple cultivars planted in each year’s trial allowed for the calculation of 153 yield effects and 162 effects in 5 fiber quality parameters. Yield and quality effects were considered in the context of related changes in total growing season degree days (GDDS) and total cool hours (CHRS) during a boll formation period 80 to 110 days after planting. May planting increased GDDS and significantly increased yields in 8 of 10 years that comparisons could be made. Micronaire and fiber elongation were the most sensitive quality parameters to planting date. June planting resulted in increased CHRS every year and a significantly higher incidence of low micronaire in 7 of 11 years. In 7 of 11 years May planting significantly reduced fiber elongation relative to June planting. Analysis of SHP temperature data show that late-April to early-May planting dates may increase yield and micronaire by maximizing GDDS and minimizing CHRS. Although this practice may be optimal to the SHP environment it may also require high-vigor seed and pre-planting irrigation. Adapting genetics to an early planting strategy might include selecting for improved seed vigor and cold germination with acceptable yield and fiber quality traits.

Field experiments were conducted in 1999 and 2000 to evaluate and adapt the Herbicide Application Decision Support System (HADSS®) program for Texas Southern High Plains cotton production. Weed management systems (in glyphosate-resistant, bromoxynil-resistant, and nontransgenic cotton varieties) included trifluralin preplant incorporated (PPI) followed by (fb) HADSS postemergence-topical (POST) recommendations (PPI fb POST HADSS), HADSS recommendations alone (POST HADSS), and Texas Agricultural Experiment Station (TAES) recommendations for the Texas Southern High Plains. In both years, effective season-long weed control was achieved with all weed management systems in the glyphosate-resistant variety, but only the PPI fb POST HADSS and TAES weed management systems controlled Palmer amaranth and devil's-claw in the bromoxynil-resistant and nontransgenic varieties, compared with POST HADSS alone. No differences in cotton lint yield or net returns over weed control costs were observed with weed management systems across variety in 1999; however, in general, the glyphosate-resistant and nontransgenic varieties produced higher yields and net returns than the bromoxynil-resistant variety. In 2000, plots from the TAES weed management system produced higher lint yields than the plots of PPI fb POST HADSS recommendations in the glyphosate- and bromoxynil-resistant varieties, but plots of all management systems yielded similarly in the nontransgenic variety. In 2000, plots from the TAES system produced the highest net returns in the glyphosate- and bromoxynil-resistant varieties. In the nontransgenic variety, the PPI fb POST HADSS and TAES weed management systems produced higher net returns over weed control costs than the POST HADSS system.

Fiber Length Distribution

The lint yield and fiber quality of cotton produced in the Southern High Plains of the USA have improved over the last decade, renewing interest in finding harvest and ginning practices that better preserve fiber quality. Previous research showed that picker harvesting and roller ginning may better preserve fiber quality, but conventional roller ginning was too slow to be adopted as the primary ginning system used for Upland cotton. Advancements in roller ginning technology have increased the ginning rate per unit width of rotary-knife roller gins to approximately equal that of saw gins. Research has shown that improvements in nep content and fiber length characteristics afforded by conventional roller ginning compared to saw ginning are maintained by the new high-speed roller gins (HSRGs). The objective of this work was to compare the fiber quality, seed quality, ginning rate, and lint turnout of Upland cotton produced in the Southern High Plains, harvested using a picker or a stripper, and ginned using saw or HSRG systems. The findings of this work indicate that the HSRG substantially improved the length characteristics of the Upland cultivars tested regardless of harvest method. Turnout was higher for the HSRG and for picker harvested cotton. Nep content was reduced for picker harvested cotton and the HSRG. The fiber length distribution and nep content improvements from the HSRG system make this fiber more attractive to ring spinning mills that produce high-count yarns for high-value products.

Incidence of High Plains Disease (HPD) in a susceptible corn cultivar was examined in relation to planting dates, insecticide treatments, and wheat heading dates during 1994 to 1996. In the High Plains of Texas, this disease of susceptible corn was related to corn planting dates and winter wheat maturity. The incidence of HPD varied greatly from year to year; however, corn planted between 16 and 20 May had the highest disease incidence. Corn planted 10 to 30 days after wheat heading had the highest incidence of the disease. Chemical control of the vector, Aceria tosichella, was ineffective, except by the use of granular insecticides applied at planting, which had some beneficial effects. Results of this study suggest that producers can reduce the incidence of HPD by planting corn before or after the peak migration of wheat curl mite from wheat.
