Abstract:
The present study was conducted to determine the “effect of salt tolerant bacteria on five different varieties of Vigna radiata L. (Mung bean) to enhance the germination, growth and biomass under salinity stress”. The adverse effect of salinity stress on five different varieties of Vigna radiata L. (Mung bean) at five different levels of salinity stress viz. 3dSm-1, 6dSm-1, 9dSm-1, 12dSm-1, and 15dSm-1 with and without salinity resistant bacteria assessed. With the increase in salinity stress, there was a delay in germination, growth, yield and physiological parameters as salinity level increased. When plants grown without salinity resistant bacteria, there was a delay in germination, growth, yield and physiological parameters. While the plants grown with salinity resistant bacteria, there was the increase in germination, growth, yield and physiological parameters. In case of growth, yield and physiological assessment, length, fresh weight, dry weight of roots and shoots, height, the number of nodules on root per plant, number of pods per plant, number of seeds per pod and per plant, the weight of seeds per pod, weight of seeds per plant, rate of photosynthesis, transpiration rate and stomatal conductance under different concentrations of sodium chloride decreased in plants without bacterial inoculum while increased in plants with bacterial inoculum. It was investigated that plants without bacterial inoculum showed a decrease in all parameters while inoculation of salinity resistant bacteria enhanced germination, growth and yield of Vigna radiata (Mung bean) plants. It was also concluded that the Inqelab variety tolerate more stress than other varieties NIFA-19, NIFA-17, Sona mung and Ramzan while Ramzan variety was the least tolerant.
