Influence of Flower Inducer on Flowering, Yield and Fruit Quality of Mango (Mangifera indica L.) cv.

Flowering is the first of various events that lay the company for mango production done yearly. The temperatures beneath 15°C readily advance floral inference. Decrease in temperature below 20 0C is prevailing in sub-sultry regions but infrequently occurs in many sweltering ones. So, an alternative blueprint for optimum flower introduction under tropical condition is basically required for growing the productivity of plant. Among various strategies progressed, paclobutrazol and potassium nitrate application is effective not only in flower inference but also in early and offseason flower result in mango. Hence, an experiment was conducted to study the effect of paclobutrazol and potassium nitrate on the blooming, fruit yield and characteristic of Amrapali mango (Mangifera indica L.) plants grown under various plant spacings at Horticultural Research Station, OUAT, Bhubaneswar all the while 2018-19 and 2019-20. The experiment was laid out in a Factorial Randomized Block Design accompanying 24 treatment blends and 2 replications. The treatment mixtures consist of four levels of arrangement (2.0 x 2.0 m, 4.0 x 2.0 m, 4.0 x 4.0 m, 8.0 x 2.0 m) and 6 levels of chemical treatments (Paclobutrazol@0.25, 0.50 and 0.75 g a.i. per beat of canopy spread and KNO3@ 2% and 4%) and a control accompanying water application. The results told that plants spaced at 4.0 x 4.0 m accompanying application of paclobutrazol 0.50 g a.i. written maximum flowering force (82.48%), fruit set allotment (6.47%) and yield (11.12 kg/tree). Whereas the product quality limits like TSS, acidity, lowering sugar, total sugar, ß carotene content are not considerably influenced by either on account of plant spacing or flower inducer to a degree paclobutrazol and potassium nitrate.
