Climate change with increasing droughts and excessive rainfall, challenges forage production for livestock industry. Intermediate wheatgrass (IWG) is a stress-tolerant grass, being introduced in Sweden as a perennial forage and grain crop. We aim to develop recommendations for nitrogen (N)-fertilization rate, harvest time, and silage conservation of IWG for optimum forage yield and feed value for livestock. A replicated field experiment will be established at three locations in Sweden to evaluate N-fertilization rate and harvest time of first cut and N-fertilization rate and regrowth interval on dry-matter yield and feed value of IWG. Fermentation quality, DM losses and aerobic stability of ensiled IWG with and without additive will be studied. N-fertilization rates and harvest regimes will be tested at demonstration fields on farms across Sweden to evaluate IWG performance under practical conditions and results will be communicated at field days, conferences, and in scientific papers.
