Yield and height of alfalfa (Medicago sativa L.) effected by rhizobial inoculation

Forage crops constitute the major component of dairy feeds and legumes have been viewed as excellent sources of N in agriculture.Biological nitrogen fixation by leguminous plants is a significant source of available N in both natural and managed ecosystems and that unique ability makes legumes especially valuble in forage program.Alfalfa is one of the most important protein sources for nutrition of livestock.As a legume, alfalfa forms symbiotic relation with nitrogen fixing bacteria Sinorhizobium meliloti, which symbiotic efficiency is determined by their individual genotype.The aim of this study was to determine the infuence of cultivar type of alfalfa and S.meliloti strain on forage yield and height of plants.Results of 2 years experiment revealed that DM yield was significantly higher with cultivars OS 88 and Mirna compared to other two cultivars (Posavina and OS 66). The effect of cultivars by strains was not significant, so inoculated cultivars performed significantly better DM yields in comparison to control (no inoculation).
