Field experiment is conducted in the station Aal Bandar in Muthanna Province in the southern region of Iraq to study the response of cowpea Vigna sinesis L. to some physical and chemical treatments during the spring season in 2015 under salt stress conditions, cowpea (local Alazmira variety) includs an experiment to study three factors : the first factor of three agricultural sulfur levels of 98% sulfur is (0-2-4) t / ha, the second factor is The magnetized water (1500 gauss and control), under the effect of irrigation with salt water (2, 4 ,8 ds/m) in the study of the following characteristics: ratio and speed of germination and the length of radicle and the strength of seedling and dry weight of the seedling , and using R.C.B.D design with 3 replicates. The results of statistical analysis showed a significant difference between the treatments where he found that the increase in the salinity of irrigation water has led to a significant decrease in the percentage of germination and strength of seedling and dry weight of the seedling amounted averages less) and without adding sulfur and irrigation normal water, where the percentage of germination (40.22%) and the strength of seedling can When the treatment (8 ds/m) (965.28) and dry weight of the seedling (9.22 mg) increases the speed of index germination (33.55 Day / seed) for the same treatments and reached the highest when the treatment (2 ds/m) and at the level of sulfur (4 t / ha) and irrigation magnetized water, where the percentage of germination (89%) and the strength of seedling (2280) and dry weight of the seedling (14.83 mg), while the average length of radicle rose high salinity and reached the top when the treatment (8 ds/m) and without adding sulfur and irrigation normal water where it reach (14 cm) and decreased average length of radicle when adding agricultural sulfur and irrigation magnetized water and a lower level of stress saline (2 ds/m), where is (9.76 cm), either triple overlap between the treatments shows significant results are clear in the percentage of germination and radicle length and strength of the cold and dry weight of the seedling while the speed of germination is not affected significantly
