The Effects of Salinity and Sodicity upon Nodulation and Nitrogen Fixation in Chickpea (Cicer arietinum)
Salinity and N2-fixation in Cicer arietinum
Chickpea is one of the most important grain legumes grown in semi-arid regions, but its production is vulnerable to environmental stress. Initiation of symbiotic nitrogen fixation is particularly sensitive to salinity. Rao et al. (563-570) find chickpea genotypes tolerant of salt-affected soil have better nodulation and support higher rates of symbiotic nitrogen fixation than sensitive genotypes.
