Description: Das Projekt "Rhizo4Bio (Phase 1): Produktion von Weizen und Gerste bei reduziertem Input im organischen Landbau" wird vom Umweltbundesamt gefördert und von Universität Gießen, Institut für Angewandte Mikrobiologie, Professur für Allgemeine und Bodenmikrobiologie durchgeführt. Wheat and barley production will be optimized under low energy input in organic farming at two experimental field stations of University Giessen and University Hohenheim. Effects of root densities (row distance), two nutrients fertilization regimes and seed inoculation of the plant growth promoting bacterium Hartmannibacter diazotrophicus will be analyzed in wheat as an important winter crop and in the summer crop barley. Quality parameters of produced grains differ for the two crops. For baking wheat protein quality and quantity is important while for malting barley high starch content is required. These parameter of the grains will be related to their root system and rhizosphere microbiome under the different treatments. The seed, root and rhizosphere bacterial and fungal microbiome will be analysed and it is expected to be specific for the two crop plants and less affected by the two soil types and locations. We aim to analyze the implication of root competition, nutrient limitation and seed inoculation on the microbiome under field conditions. Root competition will be analyzed using two different row distances under a low and optimal nitrogen fertilization regime. The plant root system might further profit from the inoculum and benefits would be derived from a more efficient root system that could capture N from fertiliser-soil sources more effectively, as well as more efficient N cycling might occur. Root architecture and biomass will be linked to microbiome analysis and grain quality and quantity. Before seeding and after harvest soil samples are analyzed for parameter estimating the sustainability of crop production. Such parameter include bacterial and fungal diversity, microbial respiration rate, soil N concentrations, protease and nitrification activity, phosphate concentration and phosphatase activity. Our results will be used for identification of optimal parameter for sustainable wheat and barley production and will lead to a bioeconomic evaluation.
