Abstract:
Arsenic (As), which is a highly toxic metalloid poses a serious risk to plants, animals and human
health has become a major public concern in many countries including Bangladesh. A pot
experiment was conducted with four different levels of arsenic at Agroforestry and Environmental
Science field of Sher-e-Bangla Agricultural University, Dhaka. There were four different arsenic
levels viz. T
1
: Control (No arsenic in the soil); T
2
: 25 mg As kg
ii
-1
soil; T
3
: 50 mg As kg
:
75 mg As kg
-1
soil. Different data on growth and yield attributes were collected and analyzed
statistically. It was observed that T
1
(no arsenic) treatment exposed the best results in terms of
plant height, stem diameter (cm), number of leaves, leaf length (cm), leaf breadth (cm), length
and weight of shoot and root, number of flowers and fruits, fruit length, fruit diameter and fruit
weight of brinjal plant compared to other treatments. The maximum fruits (3.75) were observed
in treatment T
1
(no arsenic in the soil) at 80 DAT which was significantly different from the
others. Hence, from this study, it might be concluded that cultivation of brinjal plant was sensitive
to arsenic stress and yield loss occurred with higher concentrations of arsenic. The treatment T
1
(no arsenic in the soil) exhibited the best result on growth as well as yield response of brinjal
plant followed by T
2,
T
3
and T
4.
