A field experiment was conducted in the Agricultural Research Station of King Abdulaziz University at Hada Al-Sham, 120 km Northeast of Jeddah, to evaluate the effect of soil solarization with polyethylene sheets one and two layers) amended with 30 t/ha ofanimal manure (AM) on the soil content of nitrogen (N), phosphorus (P), potassium (K), soil pH,electrical conductivity (EC), number of fungi and weed growth pre– and post– solarization. Furthermore, yield components and yield of eggplant during two seasons (2015-2016) was investigated. The N, P and K were significantly increased pre- and post-solarization.Soil fungi population and weed growth were significantly increased for pre-solarization but were significantly reduced post-solarization, with significant domination of the two layers over the single layer. No significant effect of solarization or AM on soil EC and pH but the EC was reduced under the two layers compared to the single layer. The number of flowers and fruits, the fruit weight and fruit yield increased by 98-68%, 79.3-51.7%, 145.9-90.7%, and 145.9-91% respectively under the two and one layer sheets compared to the uncovered soil. The double layers-polyethylene sheets exceed the one layer sheets in all studied parameters. The flower and fruit numbers, fruit weight and yield were also increased with the addition of 30t/ha of AM at rates of 47.6%, 33.3%, 33.3% and33.7% respectively. The second season exceeds the first season in number of flowers and fruits, in fruit weight and yield. It is recommended to cover soil with two layer transparent polyethylene sheets rather than one sheet, and to amend it with 30t/ha of AM for better yield of eggplant and control of weed and soil fungi.
