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.
