Key land degradation issues are saline discharge in scalds, gully and sheet erosion, soil acidity and sodicity, low soil fertility and aluminium toxicity (Jenkins 1996).
The classification of water for irrigation was made considering the conditions of acidity and alkalinity (pH), as well as sodicity rates as sodium adsorption ratio (SAR), the Residual Sodium Carbonate (RSC) is considered, the percentage Sodium Soluble (SSP), Sodium Percentage (% Na), the ratio Kelly (RK) and permeability index (PI) (Eaton, 1950; Todd and Mays, 1980).
High Sodicity concentration becomes a problem when enough salts accumulate in the root zone, which negatively affects crops growth.
The experimental site was prone to salinity / sodicity from year's having textural class sandy loam and situated at an altitude of 212 m above mean sea level with mean precipitation about 500 mm.
Although they are species with economic potential and adapted to the stressful conditions of the Brazilian semiarid, there is little or no information about the tolerance of these species to salinity and sodicity (Sousa et al.
Plant growth and productivity is affected by many biotic and abiotic factors [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18] Soil salinity and sodicity are global problems that are common in different part of the world.
A total of 70 soil samples in each corresponding water sample location command area were taken at different depths for salinity and sodicity assessment.
However, in agricultural fields there are three principal problems that may arise due to delivered water quality [3]: a) salinity hazard, causing osmotic pressure rises in the soil solution, and thus, it reduces water availability; b) sodicity hazard, resulting in a breakdown of soil aggregates responsible for good soil structure, which is needed for free water and air movement through the soils; and c) toxicity hazard, that affects some crops due to high concentrations of specific ions such as sodium, chloride, boron, carbonates, and molybdenum [4].
In respect to the impacts of Na on soil permeability, the sodium adsorption ratio (SAR) has long been the standard diagnostic parameter for sodicity hazard (U.
Such intensification in irrigated agriculture coupled with indiscriminate use of agrochemicals has resulted in many problems like, nutrient leaching and loss, widespread deficiency of secondary and micronutrients due to substantial decline in relative contribution of organic manures as a source of plant nutrients, salinity, sodicity, lower input-use efficiency and deceleration of total factor productivity.
