The experiment was conducted during the cropping season of 2016-17 and 2017-18 at Department of Horticulture, College of Agriculture, Dapoli, Maharashtra on 35 years old uniform mango (cv. Alphonso) trees with an objective study the effect of nutrients, irrigation and plant growth regulators on induction of post-harvest vegetative flush in mango. In the investigation the physiological behaviour of the mango trees were assessed in relation to influence of nutrients, plant growth regulator sprays and irrigation. Treatments differed significantly for rate of photosynthesis at all stages. Among the treatments the treatment foliar application of 19:19:19 (Foliar grade) 2% with irrigation (T10) recorded highest rate of photosynthesis at bud break stage than control. Treatments differed significantly for rate of transpiration at all stages. The rate of transpiration increased from before bud break stage to flower initiation stage. Among the treatments, foliar application of 19:19:19 (Foliar grade) 2% with irrigation (T10) recorded lowest rate of transpiration at before bud break stage. The highest rate was recorded by control. The rate of stomatal conductance decreased from before bud break stage to flower initiation stage in all the treatments and differ significantly. Among the treatments foliar application of 19:19:19 (Foliar grade) 2% with irrigation (T10) recorded highest rate of stomatal conductance followed by foliar application of GA 100 ppm with irrigation (T11) at before bud break stage. The lowest rate was recorded by control.
