Salinity is an hindrance to the sustainable agricultural production. It adversely affects the crop productivity and is an abiotic stress. Due to increasing salinity, the germination, height, growth and total leaf area of rice from vegetative to generative stages are inhibited. In the present Research, the effect of salinity with measurable concentrations on germination and early seedling growth of six different germplasms of rice were tested, to indicate salinity level. A Petridish experiment and a Pot culture experiment with NaCl concentrations of 0, 50, 100, 150 and 200 mM, were conducted. The results of vigour index in petridish experiment, germination %,shoot length and root length were recorded. The six rice varieties were tested and positively affected by increase of NaCl concentrations on percentage of germination and vigour index. CSR23 (Dhanrasi) rice variety recorded highest Shoot Height of 18.7 cm at lowest concentration of 25.0mM. The shoot height of 12.5 cm was recorded, at highest concentration of 200mM,in comparison with other rice varieties.
