“…Differences of N and S supply in wheat may influence protein content and composition as well as grain characteristics and dough properties (Jahn-Deesbach et al 1970, Moss et al 1981Randall and Wrigley 1986;Sarandon and Gianibelli 1990;Haneklaus et al 1995;Zhao et al 1999;Wooding et al 2000). The current practice of applying large amounts of N fertilizers to cereal crops without considering S requirements is becoming a concern for crop quality (Tea et al 2007).…”

To increase grain quality, optimal nutrient management is desirable. Recently, atmospheric S emissions from industry have decreased leading to reduced grain quality. Fertilization of N primarily affects protein concentration and biomass production while S fertilization affects the fine tuning of storage protein composition. Additionally, high N supply increases the N/S ratio to the extent that the grains could be classified as S-deficient. Although total protein amounts were not changed by the fertilizer treatments, the amounts of individual gluten proteins were altered. High resolution proteomic analysis of S-containing gluten protein fractions demonstrates that under high N supply, low or high S fertilization significantly changed 41 and 66 of the gliadin and the glutenin proteins. In particular, this change may lead to different dough and baking quality. In conclusion, a high N fertilization induces S deficiency together with a change in gluten proteins and a loss of nutritional quality of grains.

Increasing prices for wheat products and fertilizers, as well as reduced sulfur (S) contributions from the atmosphere, call for an improvement of product quality and agricultural management. To detect the impact of a time-dependent S fertilization, the quantitative protein composition and the baking quality of two different wheat cultivars, Batis and Turkis, were evaluated. The glutathione concentration in grains serves as a reliable marker of the need for added S fertilizer. The quantitation of gliadins and glutenin subunits by reversed-phase high-performance liquid chromatography confirmed that S-rich proteins significantly increased with S fertilization, whereas the S-poor proteins significantly decreased. Proteome analysis by means of high-resolution protein profiles detected 55 and 37 proteins from Batis and Turkis changed by late S fertilization. A microscale baking test using wholemeal flour was implemented for the evaluation of baking quality, and late S fertilization was found to improve the composition of gluten proteins and baking quality.

“…Dough properties and bread‐making quality differ in function of cultivar, growth conditions1–5 and fertilization regime. Yield and quality responses of winter wheat to nitrogen (N) application alone have been well documented for a wide range of cultivars, sites and climates 6–9. Although the metabolism of N and sulfur (S) are closely interrelated10 and an optimal N/S ratio in grain has been shown to improve bread‐making quality,11, 12 interactions of N with S fertilization have not been extensively studied.…”
