Improving baking quality, nutritional value and safety of organic winter wheat / Améliorer la qualité technologique, nutritionnelle et sanitaire du blé biologique, Principaux leviers agronomiques et technologiques Organic Eprints
David, Christophe; Abecassis, Joël; Carcea, M.; Celette, Florian; Corre-Hellou, Guénaëlle; Friedel, J.; Hiltbrunner, J.; Mäder, Paul; Messmer, Monika; Narducci, V.; Peigne, Joséphine; Thomsen, I. K..
The organic bread wheat market has been diversified over time through the emergence of different sale channels. Processors require organic bread wheat of higher quality and safety in order to meet the consumers’ demand. The overall objective of the AGTEC-Org project was to identify agronomical and technological ways to improve the performance of organic wheat and flour. The findings would contribute to enhanced baking quality and nutritional value of organic flour, as well as prevention of mycotoxin contamination. The project involved 9 research centers or universities from 5 European countries for a total budget of about 1.5 million €. More than 400 experimental treatments were analyzed from 23 agronomic trials and 4 lab-experiments on food technology....

Organic Bread Wheat Production and Market in Europe Organic Eprints
David, C.; Abecassis, J.; Carcea, M.; Celette, F.; Friedel, J.K.; Hellou, G.; Hiltbrunner, J.; Messmer, M.; Narducci, V.; Peigné, J.; Samson, M.-F.; Schweinzer, A.; Thomsen, I.K.; Thommen, A..
This chapter is a first attempt to analyse bottlenecks and challenges of European organic bread wheat sector involving technical, political and market issues. From 2000, the organic grain market has largely increased in Western Europe. To balance higher consumer demand there is a need to increase organic production by a new transition and technical improvement. Bread wheat is grown in a variety of crop rotations and farming systems where four basic organic crop production systems have been defined. Weeds and nitrogen deficiency are considered to be the most serious threat inducing lowest grain yield under organic production. The choice of cultivar, green manure, fertilization and intercropping legumes – grain or forage – are efficient ways to obtain high...

The influence of long-term inputs of catch crops and cereal straw on yield, protein composition and technological quality of a spring and a winter wheat Organic Eprints
Thomsen, I.K.; Samson, M.-F.; Carcea, M.; Narducci, V..
Under conditions of restricted nitrogen (N) input such as in organic farming systems, crop N uptake must rely on N mineralised from applied animal manure, crop residues and native soil organic matter. Scarcity of N may impede the production of quality grain for bread production, and input and retention of N in soil are therefore important parameters for soil fertility. Toretain N in the crop-soilsystem, catch crops may be grown in breaks between main crops where they provide a significant sink for N mineralised in late summer and autumn (Thomsen, 2005). In corporation of straw may likewise retain mineralised N by microbial immobilisation (Christensen, 1986) and will also directly add to the N mineralisation potential when the N supplied in the straw...

Vinterhvede og vårhvede - efterafgrøder påvirkede udbyttet men ikke kvaliteten Organic Eprints
Thomsen, I.K.; Carcea, M.; Narducci, V..
Kvælstofoptaget i afgrøder stammer dels fra minerali-sering fra jordens organiske materiale dels fra evt. tilført gødning. Jordens evne til at frigive kvælstof ved mineralisering, og dermed dens evne til at forsyne en afgrøde med kvælstof, påvirkes bl.a. af dyrknings-systemet, herunder hvor meget organisk materiale der tilføres jorden f.eks. i form af afgrøderester. Planters evne til at udnytte mineraliseret kvælstof afhænger bl.a. af vækstsæsonens længde. Det forven-tedes derfor, at afgrøder med lang vækstsæson bedre er i stand til at udnytte en høj mineralisering end afgrøder med kort vækstsæson.

Wheat yield and quality as influenced by reduced tillage in organic farming Organic Eprints
Peigné, J.; Messmer, M.; Aveline, A.; Berner, A.; Mäder, P.; Carcea, M.; Narducci, V.; Samson, M.-F.; Thomsen, I.K.; Celette, F.; David, C..
Organic farmers are interested in soil conservation by reduced tillage, techniques well known in conventional agriculture to protect soil quality and limit labor time and energy costs. However, organic farming and reduced tillage can modify weeds, soil structure, and thus soil nitrogen (N) mineralization which strongly influences wheat yield and quality. The main objectives of this study were to analyze how reduced tillage applied to organic wheat influenced (1) grain yield, protein concentration, and weed infestation; (2) deoxynivalenol (DON) contamination on grain; (3) technological quality parameters such as dry gluten, zeleny index, falling number, and gluten index; (4) protein composition (F1, F2, F3, F4, and F5 fractions, and UPP, gliadin/glutenin...
