The field experiments on cotton were conducted on selected farmers’ fields in Purna valley of Vidarbha region in Maharashtra during 2013-14.The treatments comprised of five different green manures, two crop residues, gypsum and control. There were nine treatments replicated on three farmers’ fields. The design of experiment was randomized block design, replicated three times, where one farmer was treated as one replication. The use of crop residues and green manuring was found beneficial as that of gypsum in physical properties of the soils in addition to gradual chemical amelioration. Although considerable improvement in chemical properties has been observed under gypsum indicating reduction in pH from the average initial of 8.31 to 8.19 and ESP from average initial of 11.15 to 7.12, but simultaneously the significant reduction has also been observed under organic amendments like dhaincha and sunhemp. The organic amendments were also found useful and superior to gypsum in improving the organic carbon available NPK and biological properties of soil. The organic amendments showed their potential not only for slow reclamation but also for improvement in characteristics of sodic soils. The organic amendments like dhaincha and sunhemp were found equally beneficial for obtaining crop yields as that of gypsum besides gradual soil reclamation.
