Impacts of Sulfur Fertilization on Yield, Grain Quality, and N Use Efficiency of Wheat

Grants and Contracts Details


An adequate supply of sulfur (S) is critical for plants to grow healthy and complete their life cycle. Historically, S has not been widely applied in crop production because crops were able to obtain enough from the soil and atmospheric deposition. However, the combination of higher yielding crops, cleaner air, and purer fertilizer products has led to increased frequency of S deficiency in many parts of the world. We propose a literature review project and field study to determine the effects of S fertilization on yield, baking quality, and nitrogen (N) use efficiency of wheat in Kentucky. The literature review study will identify the conditions in which yield and quality responses to S fertilization have been observed in wheat around the world and how grain S content relates to baking attributes. The field study will include different rates of S and N applied to several different wheat varieties at two locations in Kentucky. The results of this study will help inform Kentucky Small Grain Growers about the potential benefits of applying S.
