Basing on the results and findings of the BLE joint project 'BackProg' (2815409210/2192) the main aim of the project is the increase in efficiency of nitrogen (N) application in baking wheat production and thus improvement of N balance while preserving the yield and quality level. Especially the late high N application prevents at time a N fertilizer reduction and causes high N balance surpluses. Additionally, the introduction of varieties achieving very good bread volumes and baking quality with lower protein contents into agricultural practice is hampered by keeping the protein content as main criterion for variety assessment. Therefore, an expanded variety assessment shall be carried out and the aim to develop a reliable near infrared spectroscopic fast estimation test for wheat baking quality will be continued. By means of a field study at two locations, the proportion of the baking technologically significant glutenin macropolymers (GMP), the wet gluten content as well as the mixing potential of a given variety in different variety combinations in dependence on the N fertilizer level will be determined. The results will be will be used in the development of models for adjusted fertilizer strategies. Different companies will support these approaches. Additionally, the attempts of the preceding project to develop a reliable near infrared spectroscopic fast estimation test for wheat baking quality will be continued and the calibrations will be tested by involved companies with the aim of establishing a market-feasible procedure.
