1. Effects of Phosphorus and Potassium Application Timing on a Wheat Double Crop Soybean System The wheat-double crop soybean system is a popular choice for Oklahoma producers, as it allows for two crops in one year, and therefore, more revenue in less time. With favorable conditions and proper management, double crop soybeans are yielding as well as full season soybeans. Weather pattern shifts over the last few years have raised the question for growers if they should invest more into the summer double crop, as there is growing potential for profit. While attempting... H. Lovewell, B. Finch, R. Sharry , M. Smith, J. Souza, B. Arnall Download paper
2. Effects of Potassium and Boron on Cotton Lint Yield The importance of potassium (K) is numerously documented as it’s essential for photosynthesis, stomatal regulation, enzyme activation and chlorophyll development. While a majority of cotton production occurs in the southwest portion of Oklahoma, producers from south to northwest are implementing rotations of cotton and wheat. In the western portion of the state soil pH becomes increasingly alkaline [whereas areas in wheat production are predominantly acidic]. Although K becomes more available... M. Smith, B.

3. Evaluation of N Source in No-till Winter Wheat Nitrogen (N) source efficacy is dependent upon product used, application timing, and the condition of the environment in which it is placed. This study serves to look at how different N sources can be affected across different regions of Oklahoma, specifically in a heavy residue, no-till environment. N sources that were included in the study were Urea, Urea-Ammonium Nitrate (UAN), UAN + Anvol, and SuperU. The N sources were evaluated across nine site-years (SY) where each product had four... J.

4. Nitrogen Management of Cotton Following Corn in the High Plains Nitrogen (N) management in cotton (Gossypium hirsutum) is challenging given physiological dynamics in an indeterminate crop. Cotton performance may be harmed due not only to under fertilization of N, but also excessive fertilization. This is especially pertinent when managing cotton for earliness. Often these challenges occur in the form of delaying the onset of reproductive structures due to the crops indeterminate nature, leading to problems associated with "finishing"... R. Sharry, M.
