BACTERIAL INOCULATION EFFECT UPON YIELD CAPACITY IN ALFALFA AND ORCHARD GRASS PUBLISHED

Carmen Dragomir, Alexandru Moisuc
This work presents the bacterial inoculation effect upon the mixed alfalfa and orchard grass crop. The bacterial inoculation with strains of Rhizobium meliloti, for alfalfa, and strains of Beigerinckia and Azospirillum, for orchard grass, increases this mixture’s yield capacity with 24.5%, in the first year of vegetation, and with 23% in the second year. The most important effect was noticed in the case of the species Beigerinckia, which proves higher resistance to acid soils. A synergism relationship appears between the three bacterial species, enhancing the capacity of fixing atmospheric nitrogen.
