Influence of soil pH on cotton morphology, lint yield and lint quality
(2021-07)
The influence of commodity prices has led to an increase in cotton production in Oklahoma over the past decade. With this increase in production there has been growing interest in growing cotton in fields that have been ...
Upscaling soil moisture measurements from in situ sensors
(2021-07)
Accurate, field-scale soil moisture information is needed to match the spatial scale of land and water management decisions related to agricultural production and environmental protection. Soil moisture measurements at the ...
Optimum nitrogen rate and placement in hard red winter wheat (Triticum aestivum L)
(2021-05)
Nitrogen use efficiency (NUE) in cereal crops is at 33% on a global scale. Winter Wheat (Triticum aestivum) is one of the major cereal crops being affected by low NUE. Winter wheat is grown across the United States and the ...
Cotton harvest aid efficacy and cotton fiber quality as influenced by application timing
(2021-12)
Harvest aid chemicals are used to terminate cotton growth and promote boll opening, with optimal application timing recommended at four nodes between the uppermost first position cracked boll and the uppermost first position ...
Retrospective simulation analysis of dual-purpose and grain-only wheat production across Oklahoma with parallel gridded DSSAT-CSM.
(2021-07)
Wheat grain and forage production is an important aspect of many Oklahoma wheat management systems. Given the high interannual variability in rainfall and temperature conditions during the wheat season, agricultural producers ...
Impact of delayed nitrogen application in grain sorghum
(2021-05)
A majority of grain sorghum production occurs in the central to north west portion of Oklahoma, where the average annual rainfall is at or below 900 mm and precipitation events become less frequent. The environment conditions ...
Influence of dual top-dress nitrogen applications on winter wheat (Triticum aestivum L.) grain yield
(2021-05)
Winter wheat (Triticum aestivum) is commonly grown throughout Oklahoma and is notably the state's top cash crop. Nitrogen (N) is one of the most heavily applied nutrients in wheat by producers across the state as it is ...
Winter wheat varietal tolerance to Metribuzin tank-mixed with pyroxasulfone
(2021-12)
Metribuzin is a herbicide that is widely used in cropping systems. However, its use in winter wheat in Oklahoma has declined due to varietal sensitivity or lack of information regarding the topic. To evaluate modern wheat ...
Evaluating plant density in grain sorghum using GreenSeeker
(2021-05)
Grain Sorghum (Sorghum bicolor(L)Moench,) is a high yielding, drought tolerant crop commonly grown in Oklahoma and the southern Great Plains. Increased knowledge of agronomic production practices, such as planting densities, ...
Implementing new alfalfa technologies into water-limited environments
(2021-12)
Oklahoma is predicted to experience a shift in rainfall patterns and experience prolonged droughts in future years. With a changing environment, producers will search for new technologies to mitigate forage losses in this ...
