Abstract: The present investigation was carried out to study the Effect of crop residues, green manuring and gypsum on carbon sequestration in soils of purna valley. The study revealed that the treatment gypsum application 2.5 t ha-1 is significantly increase the production of cotton and improves mean weight diameter of soil, decreased soil salinity, soil sodicity of soil. The treatment of dhaincha and sunhemp in situ green manuring is significantly increase the productivity of cotton in salt affected soil and besides improves the physical properties bulk density and mean weight diameter of soil, decreased soil salinity, soil sodicity, free calcium carbonate of soil and increase the SMBC, SMBN, DHA, CO2 evolution, organic carbon, available nutrients and CEC of soil. Therefore from the It is concluded that the yield of cotton under gypsum was higher in comparison to organic amendments. However, the yield of cotton under dhaincha and green gram in situ green manuring was at par with gypsum indicating green manures have equal potential to improve yield of crops in sodic soils besides improving soil properties, helping soil reclamation.
