Abstract
The sunflower represents a significant economic annual plant (oilproducing and edible). Even though the sunflower is categorized as one of the
most salt-tolerant plant types and is treated as a significant plant in saline soil reclamation, the rate of its photosynthetic and growth are adversely influenced by
high levels of salt in the soil, significantly when the groundwater level rises on
the soil surface, which in turn causes the raising of soil salinity. Therefore, there
is a critical need to control salt accumulation to increase sunflower crop yields.
An evaluation of the impact of asphalt material, soil salinity, groundwater table
depth, and soluble ions on the growth of sunflower crops is presented in this paper. Several treatments were used in this study: asphalt material, bitumen material, and controlling treatment. The experiments were conducted, calibrated, and
validated during the season of spring 2019. The results show a considerable reduction in soil salinity and groundwater table depth regarding the asphalt material
control aspect, thus increasing the growth properties of the sunflower crops.
