Abstract:

A Field study was implemented during the two growing seasons (2017-2018 and 2018-2019) at Al-Tuwaitha research station, 30Km southeast of Baghdad. Phosphogypsum was applied with 6 rates (0, 25%, 50%, 75%, 100% and 125%) from gypsum requirements in salt- effected soil irrigated with saline ground water with EC of 3.2dS.m-1. Results showed Highest reduction in SAR was found at 100% PG rate of addition it was 63.24, 53.08, 26.72 and 23.77 (%) for depths of 0-20, 20-40, 40-60 and 60-80 (cm) respectively compared with control (0PG). Although results showed that Electrical conductivity was found to be the least at 75% PG at all depths it was reduced by 41.10, 34.12, 24.89 and14.64(%) compared with control.
