The research was conducted during the 2024 season in AL-Bassah/ Lattakia, Syria. The research aimed to study the effect of foliar spraying with amino acids and organic carbon on the growth and productivity of hot pepper plants, " Qorn al-Ghazal "
Ten treatments were applied as follows: T1 (control, sprayed with water only), T2, T3, and T4 (sprayed with amino acids at concentrations of 0.5, 1, and 2 g/L respectively); T5, T6, and T7 (sprayed with organic carbon at concentrations of 0.5, 1, and 2 mL/L respectively; T8 (sprayed with both amino acids at 0.5 g/L and organic carbon at 0.5 mL/L); T9 (amino acids 1 g/L+ organic carbon 1 mL/L) and T10 (amino acids 2 g/L+ organic carbon 2 mL/L).
The results showed a significant superiority of the foliar spraying treatment with amino acids 2 g/L+ organic carbon 2 mL/L in most studied traits compared to the other treatments. This treatment recorded 103.95cm plant height- 275.2 leaf/plant for number of leaves- 14855 cm2 leaf surface area– 85 flowers/plant number of flowers per plant– 53.74 fruitful buds/plant- 1.793 kg/plant yield per plant- 177.5 mg/100g of vitamin C content.
