| Abstract | ||
| A field experiment was conducted for two seasions respectively according to complete randomized design (CRD). At Al-Wehda research station, 30 km south of Baghdad in the alluvial calcareous soil classified as Vertic torrifluvent to study the effect of phosphogypsum addition with five levels ranged between 50-1050 kg/ donum in addition to control treatment on some physical parameters of soil which closely related to soil structure were mean weight diameter, modulus of repture and saturated hydraulic conductivity in addition to some Barley yield parameters which was number of seeds in spike, weight of one hundred seed, amount of seeds in one meter square area, percentage of protein in hay and in seed respectively. Results of this study showed significant difference in all studied soil and crop parameters only the modulus of repture at first season and percentage of protein in the seeds, but take increased these parameters at second season in comparison with first season. Results of this study advocates preliminary use of phosphogypsum as soil amendment However, more studies on other parameters and high causiousness of pollution of soil – water –plant system are needed. | ||
