Abstract:
A field experiment was conducted at the Horticulture Farm, Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during October 2018 to
March 2019 with of nitrobenzene application in different position of plant to
investigate the growth and yield contributing characteristics of tomato, brinjal and
chili. The experiment was laid out in the Randomized Complete Block Design
(RCBD) with three replications and four treatments (T
C
ii
: Control, T
F
: Foliar
application, T
R
: Soil application, T
F+R
: Foliar+Soil application). Significant variations
were found in both plant height and leaf number of tomato. The highest branch
number (10.3), SPAD value (55.2%), flower/cluster (18), flower number (50.3),
fruit/cluster (6.6), fruit length (61.1mm), fruit diameter (49.5mm), fruit number (29.3),
fruit weight (84.3g), yield/plant (2.5 kg) and yield/ha (96.5t) were found from T
F+R
treatment whereas the lowest values were observed from T
C
treatment. In case of
brinjal, the maximum plant height, number of leaves, branch number (12.6), fruit
length (18.85 cm), fruit diameter (48.6mm), single fruit weight (80.8g), SPAD value
(56.6), flower/plant (40.8), fruit/plant (24.1) and yield/plant (37.8kg) were found from
T
F+R
treatment while the lowest value from T
C
treatment. The highest growth and
yield parameters of chili in plant height, leaf number, SPAD value (69.2), branch/plant
(19.3), flower/plant (104.3), fruit/plant (86.7), fruit length (16.8cm), fruit diameter
(11.8mm), single fruit weight (9.2g), yield/plant (799.0kg) and yield/ha (29.5ton) was
observed from T
F+R
whereas the lowest values of these parameters were found T
C
treatment. From this experiment it can be concluded that application of nitrobenzene
in root and foliar combination treatment was suitable for higher growth and yield of
tomato, brinjal and chili.
