Effect of Azospirillum Inoculation on Growth and Yield of Lentil

Abstract

A field experiment was conducted in 2005 to evaluate the effect of some isolates of Azospirillum brasilense and Azospirillum lipoferum on growth and yield of lentil (Lens esculenta). Azospirillum inoculation significantly enhanced the early emergence of lentil seeds in the field. The inoculation caused the increase in height of the lentil plants at various stages of growth. Due to inoculation fresh weight and dry weight of lentil plant were increased during pre-flowering and post-flowering stages. Significant increase in the number of pods per plant and grain weight due to Azospirillum inoculation was observed. It was also found that the population of Azospirillum increased significantly in the inoculated root samples of lentil plants.
