Abstract:
An experiment was carried out to study the growth and yield performance of a
short stature early white maize under varying inter row and intra plant spacing.
The field experiment was conducted at the Agronomy Field of Sher-e-Bangla
Agricultural University, during March to June, 2019. Fifteen plant spacing viz. T
= 40 cm × 15 cm, T
2
= 40 cm × 20 cm, T

= 40 cm × 25 cm, T
= 45 cm × 15
cm, T

= 50 cm × 15 cm, T
= 50 cm
× 20 cm, T

55 cm × 25 cm, T
13
= 60 cm × 15 cm, T
14
= 60 cm × 20 cm and T
= 60 cm ×
25 cm were used under the present study. Results showed that the plant spacing
T
showed maximum plant height, but maximum tassel length was found from
T
3
8
. The highest leaf length, breadth and area were found from T
, while the
highest cob-leaf length, breadth and area were found from T
. The highest dry
weight plant
-1
was found from T
8
15
. In terms of yield contributing parameters, the
highest cob length (14.00 cm) and cob breadth (13.58 cm) were found from
T
14
,
while the highest 100 grain weight (26.88 g) and grain weight cob
(68.74
g) were recorded from T
8
. The highest grain yield (7.33 t ha
) and harvest
index (49.33%) were recorded from the treatment T
while the lowest grain
yield ha
-1
(4.01 t ha
-1
) was found from T
12
8
and lowest harvest index (39.53%)
was found from T
. From the above results, it may be concluded that the plant
spacing 50 cm × 20 cm showed highest grain yield (7.33 t ha
1
) and harvest
index (49.33%) and this plant spacing can be considered as the best compared
to other plant spacing.
