The study reveals that sodic conditions resulted in poor bio-synthesis in black gram plants and hence both chlorophyll ‘a’, ‘b’ and reducing and non-reducing sugar contents decreased with increasing levels of RSC water treatments. Incorporation of iron pyrites as an ameliorating agent significantly improved the availability of nutrients and enhanced the chlorophyll and sugar content. The Rhizobium inoculated treatments supplemented with 50 g iron pyrites pot-1 adjusted best among all the treatments and plants could withstand irrigation with 2.5 meL-1 RSC water without being adversely affected. Further, 7.5 meL-1 proved detrimental for plant growth and recorded maximum reduction in sugar and chlorophyll contents in the treatments which were not supplied with pyrites.
