Vegetative growth, flowering pattern and yield of mango (Mangifera indica L.) as affected by exogenous application of paclobutrazol and KNO3

Studied the response of different flowering regulatory agro-chemicals had a significantly positive impact on vegetative growth, flowering pattern and yield attributes of mango, during 2015-16 and 2016-17. Paclobutrazol is associated with a shorter internodal length and the highest flowering intensity. The study was laid out with 7 treatments in randomized block design and replicated thrice were applied on north Indian mango cultivars "Dashehari" and "Kesar" under the Banswara condition of Rajasthan. The results revealed that most of the flowering parameters were better performed with paclobutrazol @ 3.0 ml m-2 soil drench application mid-September (number of flowers/10 tagged panicle, per cent hermaphrodite flowers, per cent fruit set, least length and width of panicle) and foliar application of potassium nitrate 25 g l -1 observed maximum height and width of panicle, fruit weight, yield kg tree-1, yield t/ha.
