Dynamics of Dissolved Ions in the Rhizosphere Under Flooded Conditions

Abstract Soil salinity represents one of the major threats land degradation and desertification under arid semi-arid environments. It has an adverse influence on soil-water-plant relationships, posing serious challenges to agricultural productivity. The main objective this work was monitor effect farmyard manure (FYM) application irrigation with low-quality water dynamics dissolved salts yield rice crop ( Oryza sativa L. ) flooded conditions. Accordingly, field column experiments were carried out three treatments water, namely, tap, saline-sodic, saline, as well rates FYM (0, 12, 24 Mg ha -1 ). obtained data indicated that highest grain yields found treatment tap followed by saline amended at . loss ions (Na + , HCO 3 - Cl NO SO 4 2- from soil irrigated greater than saline-sodic water. addition led increase in leaching most particular) decreased their accumulation soils waters. regression studies revealed may be attributed resistance against secondary salinization through improving salt flux rhizosphere. Under conditions, these findings support hypothesis using conjunction a beneficial effect, while should used calcium source.
