An experiment was conducted at the green house laboratory of Khulna University, Khulna with a variety of rice BR11, to study the effect of different levels of salinity on some yield attributes of rice. The experiment was conducted with different salinity level e.g., 0, 7.81, 15.62, 23.43 and 31.25 dS m-1. Plant height, number of tillers and the biomass of the plant were recorded. The height of the plant was decreased gradually with increased levels of salinity, but the effect was insignificant from 7.81 dS m-1 salinity level i.e. below this level plant height was not decreased. The tiller number of plants was decreased significantly at 15.62 dS m-1 of salinity level. It was also observed that the biomass of plant decreased significantly from 7.81 dS m-1 level of salinity. The rice variety BR11 could be selected for the cultivation in coastal saline area as it can tolerate salinity at a higher level without significantly decreasing productivity.
