Osmotic adjustment (OA) is an important adaptive response to water stress (WS) in wheat (Triticum aestivum L.). The objectives of this study were to determine the relationships between (1) OA and drought susceptibility, (2) OA and biomass, and (3) bi

Winter wheat (Triticum aestivum L.) in the Texas High Plains often follows a crop or fallow period where atrazine was used for weed control. A study was conducted in 1991-1992 and repeated in 1993-1994 to determine if differences exist among commonly

The temperature and exposure period required to kill seed of johnsongrass, (Sorghum halepense); pigweed, (mixture of Amaranthus sp. primarily hybridus and Palmeri); kochia, (Kochia scoparia (L.) Schrad); barnyardgrass, (Echinochloa crus-galli (L.) Be

This research compared seven field bindweed control treatments to a check in a 3-yr winter wheat-sorghum-fallow rotation. Treatments included 3 wk intervals of sweep tillage combined with one or two annual applications of 2,4-D (tillage and 2,4-D). T

Field bindweed infests millions of hectares in the Great Plains greatly reducing productivity and value of land. The standard practice for field bindweed control is sweep tillage at 3 wk intervals combined with one or two annual 2,4-D applications du

Jointed goatgrass, downy brome, and horseweed are increasingly troublesome winter annual weeds during fallow periods in conservation-tillage systems in the southern Great Plains. These experiments determined the optimum weed size, vigor, and minimum

Precipitation is limited in the Southern Great Plains, and farmers must minimize production costs and control erosion. The purpose of this research was to determine economic feasibility of dryland no- and reduced-tillage systems compared with sweep p

Transpirations of cotton and velvetleaf plants competing for water and light were estimated with heat balance stem flow gauges in a controlled environment. Cotton and velvetleaf plants were grown together in pots and monitored during fluctuations in

Ammonium sulfate enhanced the initial control of johnsongrass by glyphosate and SC-0224 applied in the fall or summer. Glyphosate at 0.42 kg ha-1in combination with ammonium sulfate at 3.33 kg ha-1provided levels of fall johnsongrass control and spri

When can tillage be resumed after herbicide treatment of field bindweed (Convolvulus arvensis L.) without reducing control ? This question was answered with experiments on a clay loam soil in the semi-arid southern Great Plains in mid-summers of 1979
