Evaluating photosynthetic responses of sorghum (grain and forage) and soybean to temperature stress
(2019-07)
Physiology, growth and development of crop plants are driven by temperature and temperatures either side of the optimum lead to temperature stress. The objective of this research was to quantify the effect of temperature ...
Adapting Grain Sorghum Management Considerations for Oklahoma in the Presence of Production Challenges
(2019-05-01)
Grain sorghum (Sorghum bicolor (L.) Moench), is a crop commonly grown in Oklahoma and the southern Great Plains mainly because of its resilience and yield stability in the midst of drought conditions. However, due to the ...
Performance of Winter Wheat Varieties with and Without the ALMT1 Gene in Acid Soils
(2019-07)
Aluminum (Al) tolerant wheat cultivars are often utilized in the southern Great Plains to damper the yield limiting impacts of Al toxicity in acidic soils. The tolerance is mainly facilitated by Al-activated malate transporter ...
Evaluating Environmental Influences on Grassland Soil Organic Carbon Temporal and Spatial Distribution
(2019-07)
The soil is the largest terrestrial carbon sink, and soil organic carbon (SOC) accounts for twice as much carbon as is stored in the atmosphere. A large portion of recent atmospheric carbon increases is due to the loss of ...
Introducing grazable cover crop to wheat systems in Oklahoma
(2019-12)
Winter wheat is a valuable crop in Southern Great Plains (SGP) of the U.S. that grows from fall to spring; then the cropland is kept fallow during summer. Introducing cover crops to this system may reduce soil erosion and ...
Modeling soil treatment area requirements for conventional septic systems across a climate gradient
(2019-12)
Roughly 19% of homes in the U.S. use onsite wastewater treatment systems (OWTS) for the treatment and dispersal of domestic wastewater. In Oklahoma, upwards of 40% of single-family homes rely on OWTS for effluent removal. ...
Indirect response to yield selection for end-use quality and wheat-sensitivity indicators in hard winter wheat (Triticum aestivum L.) across six breeding cycles and three lineages
(2019-12)
A rising global population necessitates continued genetic improvement of wheat (Triticum aestivum L.), but not without oversight of intended and untended consequences along the way. This oversight is partly to blame for ...
Assessing glyphosate injury and forage bermudagrass regrowth using Canopeo
(2019-12)
Applications of glyphosate for weed control in bermudagrass pastures are permitted; however, product labels are vague regarding use after spring green-up. In-season weed control with glyphosate could be a feasible option ...
