One of the most significant vegetable crops cultivated in greenhouses and fields worldwide is chilli (Capsicum annuum L.). The Solanaceae family includes chilli, which is thought to have originated in the coastal region of western South America, extending from the equator to latitude of roughly 300 South. An essential source of minerals, vitamins, and antioxidants, chilli is a staple food in many nations and is considered to be healthful. The plant height (cm), number of leaves, number of branches, and number of flowers per plant were used to interpret how the chilli seeds responded to the various seed treatments. Number of fruits per plant, average fruit weight per plant, fresh weight per plant, and dry weight per plant are examples of yield characteristics. Five treatments were sown in order to increase the yield of chillies for the winter (rabi) season. The fifth treatment (T₀) is normal/plain water; the fifth and sixth treatments are 600 ppm CaCl₂ (600 mg/L), 1200 ppm CaCl₂ (1200 mg/L), 1800 ppm CaCl₂ (1800 mg/L), and 2400 ppm CaCl₂ (2400 mg/L), respectively. Based on the compiled findings, it is plausible that acute calcium chloride stress has a substantial effect on the growth physiology of the chilli plant.
