Present study aimed to assess the influence of plant hormones and nutrients on flowering, yield and yield attributing parameters of Mango cv. Langra under western Odisha condition. The treatments included were T₁: Paclobutrazol (Soil application)-4 ml per m of canopy diameter, T₂: Foliar spray of KNO₃ @ 2%, T₃: Foliar spray of Ethephon @ 500 ppm, T₄: Foliar spray of Ethephon @ 1000 ppm, T₅: Paclobutrazol (Soil application)-4 ml per m of canopy diameter + Foliar spray of KNO₃ @ 2%, T₆: Paclobutrazol (Soil application)-4 ml per m of canopy diameter + Foliar spray of Ethephon @ 500 ppm, T₇: Paclobutrazol (Soil application)-4 ml per m of canopy diameter + Foliar spray of Ethephon @ 1000 ppm, T₈: Control (Water). The results revealed that the treatment T₅ exhibited earliness in flowering, highest number of panicles (22.34), number of fruits (48.21), fruit yield (11.29 kg/plant), pulp wt. (189.63 g), peel% (22.23), pulp % (67.52). The untreated control plants (T₈) recorded lowest value for all the parameters studied during the period of investigation. Maximum panicle length (28.92 cm), panicle breadth (12.76 cm), fruit weight (295.10 g) was observed in T₇. From the present study, application of growth retardant like paclobutrazol along with KNO₃ exhibited better result as compared to other treatments that contribute towards the better yield of mango cv. Langra during off year under Western Odisha condition.
