Using the BioIntensive Technique of Intercropping Teff (Eragrostis tef) into Timothy to Improve the Economic Sustainability of Timothy

June 26, 2013

This project goal is to conduct and disseminate field and lab based hay production quality and economic research on timothy, a perennial cool season grass with teff, a annual warm season crop through intercropping, promoting stability and sustainability for timothy hay producers in Washington State. Intercropping timothy with teff was not successful the first or […]

Developing research information to evaluate camelina and canola in a livestock feeding system

June 24, 2012

Our project will conduct a nutritional analysis of the biodiesel byproduct, and complete an economic analysis using the camelina biodiesel byproduct as ruminant feed. The studies contained in this proposal address the 2012 BioAg priority areas: provide information that is critical in utilization of canola and camelina meals in ruminant diets and thereby promoting livestock […]
