Is There an Economic Advantage to Planting Diverse Summer Annual Forage Mixtures?
This study examined economic implications of planting summer annual mixtures of grasses, legumes, and forbs at varying nitrogen rates. No differences in yield occurred between the three mixtures, indicating that mixtures with lowest seed cost will be most economical. Applying N resulted in yield increases of 12.26 lb DM per lb N applied. Although yield responses to N were positive, sensitivity analyses showed that applying N resulted in positive net returns only when hay prices were high and N prices were low. When utilization rates are accounted for, enterprise budgets determined grazing to be 18% cheaper to implement than haying.
期刊介绍:
The Journal of Extension (JOE) expands and updates the research and knowledge base for U.S. Extension professionals and other outreach educators to improve their effectiveness. JOE also serves as a forum for emerging and contemporary issues affecting U.S. Cooperative Extension education. JOE is a refereed journal. Feature, Research in Brief, and Ideas at Work submissions undergo double-blind review, and Commentary and Tools of the Trade submissions are reviewed by the editor, Dr. Laura Hoelscher.
