The present study investigated the combined effect of chitosan and gibberellic acid on the fruit yield and production of peach (Prunus persica L.). The experiment was conducted to explore sustainable and eco-friendly strategies to enhance peach productivity, reduce chemical inputs, and promote overall plant health. The design was Randomized Complete Block (RCBD) with three replications. The experiment exhibited two factors, application of gibberellic acid (Control, 100, 200, 300 ppm) and chitosan (Control, 50, 100, and 150 ppm) abundant were damaged to take its effect on the performance of peach. An early grand variety of peach was used in this research work. Trees treated with gibberellic acid had resulted in lowest Number of fruits (9.93 kg^-1), highest Single Fruit weight (262.01 g), Fruit volume (108.75 cm³), Fruit yield tree^-1 ( 52.3 k g), F ruit fi rmness ( 4.29 k g/cm²), Total soluble solid (TSS) (12.82oBrix), Ascorbic Acid (6.3 mg/100g^-1), lowest Fruit Drop (8.63%), Chlorophyll content (48.75SPAD), lowest Fruit Juice pH (4.47), were recorded in plants representative with 200 mg L^-1 gibberellic acid concentration, Those tree which not treated with gibberellic acid resulted in highest Number of fruits (13.17 kg^-1), minimum Single Fruit weight (181.1 g), Fruit volume (89.5 cm³), minimum no of Fruit yield tree^-1 ( 44.58 k g), F ruit fi rmness ( 2.5kg/cm²), Total soluble solid (TSS) (9.22oBrix), Ascorbic Acid (4.8 mg/100 g^-1), maximum no of Fruit Drop (%), minimum Chlorophyll content (35.8 SPAD), maximum Fruit Juice pH (5.3). On the other kind, Tree treated by chitosan concentration at the level of 150 ppm have resulted in minimum Number of fruits (9.96 kg^-1), maximum Single Fruit weight (267.1 g), Fruit volume (109.17 cm³), Fruit yield tree-1 (57.2 k g), F ruit fi rmness (4.55 k g/cm²), Total soluble solid (TSS) (13.81oBrix), Ascorbic Acid (6.17 mg/100 g^-1), minimum Fruit Drop (7.4%), Chlorophyll content (51.33SPAD), minimum Fruit Juice pH (4.49). while trees that were not treated with chitosan concentration is resulted in maximum, Number of fruits (12.38 kg^-1), minimum Single Fruit weight (185.6 g), Fruit volume (88.67 cm³), Fruit yield tree-1 (40.81 k g), F ruit fi rmness ( 2.8 k g/cm²), Total soluble solid (TSS) (9.28oBrix), Ascorbic Acid (5.1 mg/100 g^-1), maximum Fruit Drop (11.7%), Chlorophyll content (33.8SPAD), maximum Fruit Juice pH (5.38). A recorded plant of control treatment has been clear since the investigate data that collected gibberellic acid and chitosan consideration improved peach quality and yield. It will be concluded to gibberellic acid application at the rate of 200 ppm and chitosan use of 150 ppm widely improved fruit yield and quality feature of peach. Therefore, gibberellic acid and chitosan use (200 ppm and 150 ppm) are recommended for attain to a developed growth and as well as peach production in Peshawar climatic environment.
