Abstract: An experiment was carried out to study the effect of different flower inducing treatments viz. ethephon 0.625 ml l-1 (T1), KNO3 10 g l-1 (T2), ethephon 0.625 ml l-1 + KNO3 10 g l-1 (T3), KH2PO4 10 g l-1 (T4), pacobutrazol 4 ml m-1 canopy radius (T5), decapitation in October (T6), decapitation (June) + urea 5g l-1 (July) + KNO3 10 g l-1 (T7) on 10 years old mango cv. Himsagar at Horticultural Research Station of Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India during 2012–14. Among different treatments, paclobutrazol and ethrel 0.625 ml l-1 + KNO3 10 g l-1 were found most effective in production of higher flowering shoots with higher content of total non-structural carbohydrate (starch and sugar) and C:N of leaves both in the ‘on’ and ‘off’ year. Yield was recorded higher with the same treatments of paclobutrazol and ethephon 0.625 ml l-1 + KNO3 10g l-1.
