Abstract:
The present piece of work was performed at the experimental field of Sher-e-
Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period
from November, 2015 to April, 2016 to study effect of effect of planting
configuration on the growth and yield of white maize. The experiment
comprised of two factors viz. factor A: Two white maize varieties (V
= KS510
and V
2
= PSC-121) and factor B: five plant spacing (T
= 40 cm × 25 cm
spacing, T
2
= 50 cm × 25 cm spacing, T
3
1
= 60 cm × 25 cm spacing, T
= 70 cm ×
25 cm spacing and T
= Double rows of 50 cm × 25 cm spacing). The
experiment was laid out in Randomized Complete Block Design (RCBD) with
three replications. The results of the experiment revealed that, both varieties of
white maize showed similar result in most of the plant characters. The highest
grains cob

(506.5), grains row

(36.05) and rows cob
-1
(14.11) were recorded
from plant spacing 70 cm × 25 cm. Plant spacing double rows of 50 cm × 25
cm performed best among five plant spacing in case of 100 grain weight (40.17
g), grain yield (9.68 t ha
-1
), stover yield (13.62 t ha
-1
), biological yield (23.30 t
ha
-1
) and harvest index (41.47 %). Plant spacing 40 cm × 25 cm showed the
lowest result in all yield and yield contributing characters. Interaction of variety
PSC-121 with double rows of 50 cm × 25 cm plant spacing gave highest 100
grain weight (40.33 g), grain yield (10.50 t ha
-1
4
), stover yield (14.01 t ha
),
biological yield (24.51 t ha
-1
) and harvest index (42.84 %). On the other hand
interaction of variety PSC-121 with plant spacing 40 cm × 25 cm showed the
lowest results. So, it may be concluded that white maize variety PSC-121along
with double rows of 50 cm × 25 cm plant spacing might be suggested to be
followed in white maize production.
