Abstract:
The experiment was conducted at the Horticulture Farm of Sher-e-Bangla
Agricultural University, Dhaka dunng the month of October 2007 to March
2008
to study the efThet of plant growth regulators on growth and yield of tomato. The
experiment was laid out in Randoniiv.ed Coniplete Block Design with three
replications. Three plant growth regulators ((1 NAA. GA and (1:4
IAA)
and three tomato varieties (V
1
BARI Tomato 3, V
BARI Tomato 7 and
V=BARl Tomato 9) were used in this experiment. In case of plant growth
regulators the results of the experiment showed that G produced hIghest tiumber
of branches per plant (12.37), number of flower per plant
(91.51) and yield (126.6
t/ha). In case of tomato variety highest number of branches per plant (11.8]).
number of flower per plant
(91.66) and yield (99.74 hIm) produced Liv V2. For
combined elièct V:G produced highest number of' branches per plant (15.23).
number of flower per plant (105.2) and yield
(151 .5 h/ha), which also gave the
best economic return (3CR8.44). It may he concluded that IAA with BARI
Tomato 7 produced the best result.
