Study on Types of Salinity and Nitrogen Fertilizer in Soil &; Barley : Effect of Cl/SO4 ratios in irrigation water and nitrogen on soil properties, yield and yield parameters of barley

Logical usage of saline water as an irrigation resource, addition to agricultural production rising can decrease for competing of none saline water. Numerous salinity-nutrient interactions are occurring at the same time but whether they ultimately affect crop yield or quality depends upon the salinity level and composition of salts, the crop species, the nutrient in question and a number of environmental factors. In saline soil as existence of more than one or several nutrients threshold in soil solution, plant nutrition imbalanced and this matter complicate study of plant response to fertilizers. Whenever plant affect by salinity stress, nitrogen uptake decrease more than another nutrients.This study evaluates the effect of Cl-/SO4= ratios in irrigation water and nitrogen fertilizer on soil properties, yield and yield parameters of barley.
