Abstract:
An experiment was conducted to examine the effect of growth regulator
(Ripen-15) and fertilizer management practices on the growth, flowering
and yield of bitter gourd (Gaj Corolla) during April to July 2006 at the
Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka. Four
different concentrations of growth regulator (Ripen-15) viz. H1 (100
ppm), H2 (200 ppm), H3 (300 ppm) with control (No growth regulator)
and four different fertilizers; F
1
(Cowdung), F2 (Inorganic fertilizer), F
(Cowdung + Inorganic fertilizer) and F0 (Control) were applied in the
experiment. All the result of experiment had significant influences on all
parameters studied i. e. time to first flower, number of male and female
flower per plant, ratio of male/female flower, number of node with first
flower, number of branches per plant, number of fruits per plant, length
of fruit, diameter of fruit. Maximum number of female flower per plant
was obtained from H2 (24.4), F3 (21.2) and F3H2 (26.4) cm). Maximum
yield (t/ha) was obtained from H2 (18.1 t), F3 (19.7 t) and F3H2 (22.9 t)
followed by F:d 11 (20.6 t).
