Agriculture occupies a substantial proportion of the European land, and consequently plays an important role in maintaining natural resources and cultural landscapes, a precondition for other human activities in rural areas. Legumes include many agriculture important grain, pasture and agroforestry species that are well known for their ability to fix nitrogen through root nodules [1, 2].Alfalfa (Medicago sativa) is a major forage legume, with an average annual value of more than $8 billion in the USA alone [].It's high biomass productivity also makes alfalfa a potential bioenergy legume [].
