The present experiment was carried out at the Experimental Farm, Faculty of Agriculture and Natural Resources, Aswan University, Aswan, Egypt, during the seasons of 2019/2020 and 2020/2021. This study aimed to determine the effect of compost, ascorbic and salicylic acids on the growth and yield and its components of coriander (Coriandrum sativum L.) plants. Compost was applied to the soil before planting at 0, 6 and 12 m3/fed, while ascorbic acid and salicylic acid treatments were added as a foliar spray at 100 or 200 ppm individually or combined. The obtained results proved that utilizing compost increased plant height, number of branches/plant, herb dry weight/plant, number of umbels/plant, the weight of 1000 seeds/plant, fruit yield/plant, fruit yield/plot,  fruit yield/fed, volatile oil %, shoots' total phenolics, fruits' total nitrogen and total chlorophyll in leaves. The most increments of these traits were recorded by adding compost at 12 m3/fed. Spraying plants with either ascorbic or salicylic acid individually or together improved the growth, yield, and yield attributes. It can be said that spraying with ascorbic acid at 200 ppm has the advantage of improving growth, yield and its components compared to the other treatments. In addition, the combined treatments resulted in increasing all examined coriander traits. The highest growth and yield parameters were obtained in coriander's plants treated with compost at 12 m3/fed combined with 200 ppm ascorbic acid
