For evaluating the effect of poly amino acid (poly amino carboxylic acid 18 %), fulvic acid (potassium fulvate 10 %) and seaweed extract (potassium alginate 10%) as foliar spray on the growth, production and some chemical constituents of Hot pepper Capsicum annuum L. ″Super Nar″ cultivar a field experiment was done. Through the 2022 and 2023 summer seasons, this experiment established in the Ghazala farm, an experimental farm owned by Zagazig University's Faculty of Technology and Development in Egypt. After 30, 60, and 90 days from the transplanting date, any stimulating ingredient should be sprayed three times per season. A completely randomized block design was used to distribute the seven treatments in the trial. In comparison to the other treatments being studied, the utilizing of seaweed extract at a concentration of 4 ml/l resulted in a substantial improvement in plant height, dry weight, number of leaves and dry weight of leaves per plant. In comparison to the control, pepper plants which sprayed with fulvic acid, poly amino acid, and seaweed extract produced a considerably higher amount of fruit per feddan. In comparison to the other treatments, the seaweed extract treatment (at 4 milliliters/liter) produced the highest N, P, and K percentages and the highest total soluble solids (TSS) content. In general, it is beneficial to spray hot pepper plants with 4 ml/l of seaweed extract three times/season in order to achieve optimal pepper growth, high fruit yield, and mineral content.
