The present study was accomplished to find out the effects of salinity on germination, growth, physiological and biochemical processes of two different groundnuts (Arachis hypogaea L.), varieties viz., Dacca-1, and Zhinga groundnut. The experiments consisted of five salinity treatments viz., control (no salinity), 3, 6, 9, and 12dS/m during germination and vegetative stage of groundnut varieties. Results showed that germination percentage of both the groundnut varieties was significantly decreased with the increase of salt concentration. During the germination stage, maximum shoot and root length, shoot and root fresh weight and shoot and root dry weight of groundnut varieties were recorded from Zhinga groundnut variety at salt stress. The same result occurred during the vegetative stage of Dacca-1 variety while the Zhinga groundnut variety showed maximum parameters than Dacca-1. Fresh weight, as well as dry weight, of shoots and roots of both the groundnut varieties was also decreased with the increase of salt concentrations while leaf proline concentrations were increased among these varieties. Salinity caused significant (P<0.001) reduction in chlorophyll a, chlorophyll b, and total chlorophyll content in both the genotypes. Between two genotypes, Zhinga groundnut recorded higher chlorophyll a, chlorophyll b and total chlorophyll content than Dacca-1. From the studies, it is concluded that the groundnut genotype Zhinga was identified as the tolerant genotype to salt stress than Dacca-1. Overall results indicate that high salinity condition is not suitable for growing the groundnut.
