THE relatively small acreage devoted to the culture of alfalfa in comparison to the total hay acreage in the humid Northeastern States is due, to a large extent, to the exacting environmental requirements of this legume for its establishment, survival and continued productivity. Even under the best conditions of soil fertility and management, and without apparent extensive winter injury, a gradual elimination of alfalfa from meadows seeded to mixtures of this legume with red clover, timothy and in some cases, Ladino clover, has been observed frequently in the so-called alfalfa soils of central New York. The present experiments were initiated to determine some of the effects of different ecological factors upon the establishment and survival for a 3-year period of alfalfa in mixtures with other forage species and the subsequent results on hay production. Particular attention was given to the effect of increasing amounts of competing species in the seeding mixture.
