The experiment was carried out in farmers field, Hiriyur, (Chitradurga district) during the year 2024-2025 on “Influence of plant growth substances on fruit quality in pomegranate (Punica granatum L.) cv. Bhagwa”. The experiment was laid out in Randomized Block Design comprising eleven treatments viz., T1-Control (water spray), T2-Napthalene acetic acid (NAA) @ 20 ppm, T3-Napthalene acetic acid (NAA) @ 40 ppm, T4-6-Benzyl adenine @ 20 ppm, T5-6-Benzyl adenine @ 40 ppm, T6-Cycocel @ 1500 ppm, T7-Cycocel @ 2000 ppm, T8-Amino acids @ 1000 ppm, T9-Amino acids @ 2000 ppm, T10-Seaweed extract @ 2000 ppm and T11-Seaweed extract @ 4000 ppm with three replications, sprayed at an interval of 75 and 120 days after first irrigation. Among the treatments, T11-Seaweed extract @ 4000 ppm recorded highest total soluble solids (17.97 ºBrix), total sugar (14.72 %) and TSS-Acid ratio (46.38). T7-Cycocel @ 2000 ppm recorded maximum anthocyanin (23.23 mg/100 g) and minimum acidity (0.39 %). As a result of the research, Cycocel @ 2000 ppm and Seaweed extract @ 4000 ppm proved to be enhancing fruit quality in pomegranate.
