The role of Phosphogypsum applied to soil partly affected with salinity on yield and growth of corn (zea mays)

Abstract

This trial was cared out in plastic pots to investigate the role of Phosphogypsum applied to soil partly affected with salinity on yield and growth of corn.The Phosphogypsum was added to soil partly salinity with the following percentage: 0%, 0.1%, 0.2%, 0.3%, 0.4%, and 0.5%. The pots were arranged in (CRD) with three replicate.The result revealed that a signification increase plant height and the dry weight of corn with increase in applied Phosphogypsum. In addition signification increases in the available Phosphor in soil after agriculture for all levels except the fourth level. Increase in Phosphor, Sulfate and redaction in Chloride in plant were found with the increase of Phosphogypsum application.
