Influence of nitrogen timing on winter wheat grain yield and evaluation of nutrient management on the stratification of soil parameters in no-till
(2021-12)
Visual symptoms of nitrogen (N) deficiency is common in winter wheat fields. Whether it is due to unavailability of suitable application equipment or unfavorable application conditions, the crop may go a significant period ...
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 ...
Improving the drought risk assessment and preparedness for winter wheat farming in Oklahoma
(2022-07)
Droughts pose a persistent threat to agriculture in the Southern Great Plains (SGP). Oklahoma is a major contributor to dryland winter wheat farming in the SGP, acrop that is highly susceptible to drought episodes. Modern ...
I. Evaluation of seed treatments and nitrogen on soybean nodulation and grain yield.II. Influence of pre-plant nitrogen and phosphorus on winter wheat grain yield and quality
(2021-05)
Soybeans (Glycine max) are known to form symbiotic relationships with soil microbes and conduct biological nitrogen fixation (BNF). However, only 50-60% of the crop's nitrogen (N) requirement is met through this process. ...
Soil nitrogen storage and mineralization potential in a winter wheat system under long-term nitrogen fertilization
(2022-05)
In winter wheat systems, crop nitrogen(N) uptake is sourced primarily from inorganic N fertilization and N mineralization from soil organic matter(SOM). N mineralization is a dynamic N cycling process that relies on many ...
Integrated management of Bromus Species in grain only winter wheat production of the southern Great Plains
(2021-11)
Bromus spp. including rescuegrass, cheat, and downy brome are difficult to manage winter annual grass weeds in southern Great Plains winter wheat. Producers can manage Bromus spp. in herbicide-tolerant wheat, but control ...
