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 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 decreased soil salinity, soil sodicity, free calcium carbonate of soil, available nutrients, CEC and ESP of soil. The application of gypsum found most beneficial in increasing soluble cations Ca++, Mg+ and K+ and reducing Na++ concentration in soil as comparison with the application of green manures dhaincha, sunhemp and crop residues. 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.
