This research work was conducted to evaluate the efficacy of Rhizobium trifolii in enhancing the salt tolerance of Trifolium alexandrinum (Berseem or Egyptian clover), protein value of fodder and nitrogen fixation in the soil. Three salinity levels (8,12, 16 dS m-1) were developed in a loamy soil in pots. A similar set of inoculated pots with Rhizobium trifolii was also arranged. Berseem crop was grown in both of the sets. The data indicated that total green and dry matter yield as well as root dry weight of berseem decreased consecutively with increase in salinity level while Rhizobium inoculation created a positive effect and these parameters remained significantly higher than the similar levels without inoculation. Nodulation and nodule dry weight was promoted markedly by inoculation and depressed significantly with consistent increase in salinity. Nitrogen percentage of berseem shoot increased with inoculation and decreased significantly at 8 dS m-1 but further increase in salinity had a little effect. Percent nitrogen of soil and nitrogen fixation in soil was enhanced significantly by inoculation and decreased significantly with increase in salinity. Inoculation was helpful to keep the protein content higher. Soil ECe and pH were lowered.

It's a nice article helpful to Bangladeshi scientist as well as science students working in coastal saline areas. Thanks.
