Influence of Flower Inducer on Flowering, Yield and Fruit Quality of Mango (Mangifera indica L.) cv. Amrapali Planted under Different Spacing

Flowering is the first of several events that lay foundation for mango production every year. The temperatures below 15°C readily promote floral induction. Decrease in temperature 20 0C common sub-tropical regions but seldom occurs many tropical ones. So, an alternative strategy optimum flower initiation under condition essentially required increasing productivity plant. Among different strategies evolved, paclobutrazol and potassium nitrate application effective not only induction also early offseason mango. Hence, experiment was conducted to study effect on flowering, fruit yield quality Amrapali (Mangifera indica L.) plants grown plant spacings at Horticultural Research Station, OUAT, Bhubaneswar during 2018-19 2019-20. laid out a Factorial Randomized Block Design with 24 treatment combinations 2 replications. consist four levels (2.0 x 2.0 m, 4.0 8.0 m) 6 chemical treatments ([email protected], 0.50 0.75 g a.i. per meter canopy spread KNO3@ 2% 4%) control water application. results revealed spaced m recorded maximum flowering intensity (82.48%), set percentage (6.47%) (11.12 kg/tree). Whereas parameters like TSS, acidity, reducing sugar, total ß carotene content are significantly influenced by either due spacing or inducer such as nitrate.
