Abstract:
A field experiment was conducted at the Agronomy field laboratory of Sher-e-Bangla
Agricultural University, Dhaka, Bangladesh during November, 2015 to April, 2016 in
rabi season with a view to study the growth and yield variations in chickpea as
influenced by planting geometry. The experiment was carried out in split plot design
considering three variety’s i.e. BARI Chola-5, BARI Chola-6 and BARI Chola-9 in the
main plot and five spacing viz. Sp
1
= 40 cm × 10 cm, Sp
2
= 30 cm × 30 cm,
Sp
3
= 40 cm × 40 cm, Sp
4
= 50 cm × 50 cm and Sp
5
= 60 cm × 60 cm. The recommended
dose of N, P

O

, K

O, B at the rate of 20, 40, 20, 1 kg ha
-1
, respectively were added to
the soil of experimental field. Results indicated that among the varieties BARI
Chola-5 performed well and gave maximum number of branches plant
(46.93), leaves
plant
-1
(344.8), above ground dry weight plant
-1
(22.92 g), pods plant
(50.43), seed
yield (0.78 t ha
-1
); stover yield (1.09 t ha
-1
) and biological yield (1.87 t ha
). In case of
different spacing treatment 40 cm × 40 cm gave maximum branches plant
(49.62),
leaves plant
-1
(353.6), above ground dry weight plant
-1
-1
-1
(24.06 g), pods plant
(47.49).
Wider spacing had 33.67 % and 54.14 % value advantages over low yielder spacing
regarding above ground dry weight plant
-1
and pods plant
-1
-1
-1
-1
. Narrower spacing
(40 cm × 10 cm) gave more yield than wider spacing due to more number of plants per
unit area. In combination treatment BARI Chola-5 along with spacing of 40 cm × 40
cm gave maximum branches plant
-1
(60.22), leaves plant
-1
(450.2), above ground dry
weight plant
-1
(26.89 g), pods plant
-1
(66.00). Seed yield (1.82 t ha
) was recorded
maximum from treatment BARI Chola-5 combined with 40 cm × 10 cm and the
minimum 0.23 t ha
-1
with BARI Chola-6 combined with 60 cm × 60 cm. From the
results of present study it can be concluded that wider spacing influenced individual
plant with vigorous growth and development but failed to show optimum seed yield
due to lower number of plant per unit area.
