Mango (Mangifera indica L.) is one of the most important fruit crops of many tropical and sub-tropical countries of world which belongs to the family Anacardiaceae (Nakasone and Paul 1998 and Purseglove 1972). The experiment was carried out in Horticulture Garden of Bihar Agricultural College, Sabour during Rabi season with the objectives focused in this direction on the effect of GA3 application on physiological regulation of flowering and maturity in mango [Mangifera indica L.] cv. Langra. A critical analysis of data revealed that wide range of phonological observation was observed on morphological traits. The traits such as panicle emergence (14.55 Days), days to 50 % flowering (38.45 Days), bud break to full bloom (45.85 Days) and period of full bloom to maturity (110.43 Days) was recorded with gibberellic acid (GA3) @ 100 ppm, respectively. The other traits like panicles per tree (1044.45) and maximum leaf area (89.73 cm2) were recorded when application of gibberellic acid @ 200 ppm respectively. The other traits like length of panicles (26.73 cm) were recorded when application of gibberellic acid @ 0 ppm while flowering intensity (67.09 %) was recorded when spray of gibberellic acid @ 100 ppm. A wide range was observed with application of gibberellic acid on Physiological parameters.
