Low temperatures have a negative impact on eggplant growth and development. Also, cold stress especially causes yield-limiting during the Autumn growth season. So, the experiment was carried out in the net house at the Central Laboratory for Agricultural Climate, Giza, Egypt during the 2020/2021 and 2021/2022 seasons. These studied factors were three different levels of phosphorus fertilizer (50,100 and 150% from recommended before transplanting doses) and foliar spraying with potassium silicate (0, 1, 2, 4 and 8gl-1). The effect of the two studied factors on growth, yield and quality of eggplant plants was tested. The experimental design was split-plot design with three replicates. The obtained results showed that applying 100% of phosphorus fertilizer has a significant positive effect on all studied traits. Otherwise, the least values were recorded by applying 50% of phosphorus fertilizer in the two seasons. Foliar spraying with potassium silicate at 1gl-1 increased all measured values on eggplant plants. On the contrary, the lowest values were reported by foliar spraying with potassium silicate at 8gl-1 in the two study seasons. The application combined 100% of phosphorus fertilizer rate and foliar spraying with potassium silicate at 1gl-1 had the best of all measured parameters. Alternatively, the lowest values were obtained by the application combined application 50% of phosphorus fertilizer and foliar spraying with potassium silicate at 8gL-1 under conditions trail.
