Abstract:
A field experiment was conducted in the Horticultural Farm of Sher-e-Bangla
Agricultural University, Dhaka-1207 during the period of April to August
2007 to study the effect of plant growth regulators and fertilizer management
practices on flowering, growth and yield of snake gourd. The experiment was
consisted of two factors. Factor A: Different plant growth regulators viz.
control (H0), Ripen-15 (H1), IAA (H2) and Ripen-l S + IAA (HJ) and FactorB:
Fertilizer management practices viz. control (F0), organic manure (F 1) and
inorganic fertilizer (F2). The experiment was laid out in two factors
Randomized Complete Block Design (RCBD) with three replications. The
tallest plant at I 51 flowering time ( 169.3 cm), the lowest ratio of male and
female flower (3.21 ), the maximum fruit weight (225.5 gm) and the highest
yield (20.47 t/ha) were recorded from the application of Ripen-l S + IAA
(HJ) and the minimum was recorded in control condition. The tallest plant at
flowering (I 67.3 cm), the lowest ratio of male and female flower (3.65), the
maximum number branches per plant (7.67), the maximum fruit weight (213.6

gm) and the highest yield (I 8.25 t/ha) were recorded from the application of
inorganic fertilizer (F2) and the minimum was recorded in control condition.
Interaction effect between plant growth regulators and fertilizer management
practices showed statistically significant variation in consideration of all the
recorded characters. The combination of Ripen-l S + lAA and inorganic
fertilizer (H3F2) gave the highest gross return (Tk. 458,000/ha) and the lowest
gross return (Tk. 152,000/ha) was obtained in the control condition where no
plant growth regulator as well as no fertilizer was applied. The combination of
Ripen-15 + lAA and inorganic fertilizer (H3F2) gave highest benefit cost ratio
(2.36).
