Effect of Agricultural Sulfur on Reduce the Effects of Irrigation Water Salinity on growth of the Broad Bean Plant in Southern Iraq

Broad bean (Vicia faba) is one of the most important crops grown in central and southern Iraq and has great economic importance. Its cultivation has been affected in recent years by the high level of salinity in irrigation water, which has led to the decline of its cultivation in many rural areas previously known for its cultivation in areas close to the banks of the Euphrates River. This forced us to estimate how much this plant is affected by salinity levels and treat it with agricultural sulfur to reduce the damage. The experiment was conducted during the 2022-2023 growing season at the Second Research Station Al-Bandar affiliated with the College of Agriculture / Al-Muthanna University, to study the effect of irrigation with saline water on broad bean plants grown in 5 kg pots at four salinity levels (0, 4, 8, 12 ds m-2). Agricultural Sulfur was added at three levels (0, 3.0, 6.0 g pot-1). The experiment was designed following the Randomized Complete Block Design (R.C.B.D.) with three replicates below a significant level 0.05. The results showed significant differences using agricultural sulfur with salinity-free treatments in vegetative properties and chemical properties. However, the results also showed the positive effect of adding agricultural sulfur at high levels of 6 g pot-1when irrigated with saline water up to 12 ds m-2. As for the chemical properties, the results showed the extent of the effect of adding agricultural sulfur 6 g plant-1 anvil with irrigation with water salinity up to 12 ds m-2 on the chemical properties. The result confirmed that adding agricultural sulfur to pots planted with riverside soil reduced the harmful effect of irrigation with saline water on the growth of some legume plants.
