Abstract:
The experiment was conducted at the Department of Agricultural Chemistry, Sher-eBangla
Agricultural
University,
Dhaka 1207, during the period from November 2017 –August
2018 to find out the effect of nitrobenzene on plant growth, yield and minerals content of
tomato. The experiment comprised of two factors. Factor 1- tomato varieties, V
(BARI
Tomato- 1) and V
(BARI Tomato-2) and factor 2- Plant Growth Retardant ni t r obenzene
doses (4 Doses): T

Randomized Block Design (RCBD) with four replications and there were all together 32 plots.
Application of nitrobenzene significantly influenced the height, yield and minerals content of
tomato. The highest plant height was found
from V

(97.25 cm) and T
(97.5 cm) whereas the
shortest from V

(76.00 cm) at harvesting time. In case of treatment
combination, the tallest plant (95.5 cm) was found in V

at final harvest time. Considering variety, maximum yield per hectare
(70.98 t) was observed in V

and minimum (59.0 t) in V
. In case of
nitrobenzene
treatment,
maximum yield per hectare (82.62 t) was observed in T

and minimum (46.96 t) in T
.
In case
of combined effect of variety and
nitrobenzene
doses, maximum fruit yield per hectare (93.85

. From this
experiment, 2 mL dose of
nitrobenzene and variety V
(BARI Tomato-2)
performed best
yield and minerals content.
