Abstract
An experiment was conducted during November 2018 to March 2019 at the Agronomy
field of Sher-e-Bangla Agricultural University, Dhaka to study influence of spacinng on
growth and yield of hybrid maize. The experiment comprised of two factors having two
varieties (V
1
= SAU Hybrid Vutta 1 and V
2
= SAU Hybrid Vutta 2 ) and six spacing (S
=
50 cm x 20 cm, S
2
=
55 cm x 20 cm, S
3
= 60 cm x 20 cm, S
4
= 65 cm x 20 cm, S
= 70
cm x 20 cm and S
=75 cm x 20 cm). The experiment was laid out in the Randomized
Complete Block Design (RCBD) with three replications. Results revealed that both
the individual and the interaction treatments had effect on different growth, yield
contributing and yield parameters of SAU Hybrid Vutta 1 and SAU Hybrid Vutta 2. The
highest dry weight plant
6
-1
(149.81 g) was found from the spacing S
. In case of yield
contributing parameters the highest cob length (17.17 cm), number of grain cob
(524.50), cob weight plant
-1
(232.31 g) and total grain weight cob
-1
6
(158.70 g) were found
from the spacing S
6
. The highest grain yield (12.39 tha
-1
), stover yield (13.59 tha
),
biological yield (25.99 tha
-1
) were also found S
but highest harvest index (47.87%) was
obtained from the spacing S
4
6
. The yield contributing parameters such as the lowest cob
length (15.17 cm), number of grain cob
-1
(426.00), cob weight plant
-1
(176.14 g), total
grain weight cob
-1
(120.15 g), grain yield (9.61 tha
-1
), stover yield (10.51 tha
),
biological yield (20.12 tha
-1
) were found in S
but the lowest harvest index (46.56%)
was obtained from the spacing S
2
1
. The highest plant height (52.27 cm, 163.07 cm and
255.67 cm at 30, 60 and 90 DAS), total grain weight cob
-1
(175.27 g), grain yield (13.50
tha
-1
), stover yield (13.92 tha
-1
), biological yield (27.42 tha
-1
) and harvest index
(49.29%) were obtained from the treatment combination of V
2
S
. The lowest grain yield
(8.19 t ha
-1
), stover yield (9.22 tha
-1
), biological yield (17.41 tha
6
-1
) were found from
treatment combination of V
1
S
but the lowest harvest index (46.07%) was obtained from
the treatment combination of V
1
1
S
2
. So, the treatment combination of V
can be considered as the superior treatment combination compared to other treatment
combinations under the present study.
