Soil pH, exchangeable sodium and exchangeable sodium percentage decreased by 0.09 units, 25.4% and 30% under gypsum, and by 0.06 units, 19.1% and 23.3% under dhaincha green manuring after two years. However, organic amendments (OA) performed better in improving nutrient status compared to gypsum. The OA reduced sodicity and improved nutrient availability in the order dhaincha>sunhemp>leucaena>cowpea>green gram>composted cotton stalk>biomulch. The practice of green manuring in sodic soils enhanced nutrient supply and showed potential to reclaim sodic soils. Hence, this study clearly demonstrated that dhaincha and sunhemp can represent a potential alternative choice to gypsum scarceness for management of sodic soils under a scenario of increasing sodicity.Not Availabl
