The Impact Of Asphalt Material And Soil Salinity On Crop Growth Of Sunflower

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.
