Abstract: Hippeastrum hybridum cv."Baby star" is grown for its ornamentals' cut spike as well as a pot and bedding plants.Plants were exposed to eight foliar application with one month intervals of two biostimulants, dry yeast extraction at the rates of 3.0-4.0-5.0 and 6.0 g/l and seaweed extraction (algal extraction) at the level of 1.0-2.0-3.0 and 4.0 ml/l and control treatment (0.0).Using seaweed extraction at 2 ml/l greatly affected the vegetative growth, resulting in the highest plant height, leaves fresh and dry weights, leaf area.The lowest flowering time resulted from using seaweed at 1 ml/l.The vase life of cut spikes was increased by using dry yeast extraction at the level of 5 g/l or seaweed extraction at 3 ml/l, in the two seasons.However, spike length and its dry weights were greatly increased by 4 ml/l of seaweed foliar spray.The highest cut flowers in vase was obtained using yeast foliar spray at 5.0 g/l or seaweed foliar spray at 3ml/l Bulbs volumes and weights were also affected using seaweed foliar spray at the rate of 2 or 4 ml./L in the two seasons, respectively.Seaweed foliar spray 2 ml/l resulted in the highest chlorophyll content as well as yeast extraction at 4.0 g/l.However, the highest anthocyanin content in petals' spike was obtained using 5 g/l from yeast foliar application.
