Abstract:
A field experiment was carried out at the Agronomy Field of Sher-e-Bangla
Agricultural University, during the period from July to October, 2018 to study
the growth, phenology, yield attributes and yield of a white maize genotype
SAUWMOPMDT273 under different planting configurations. Fifteen planting
configurations viz., 40 cm × 15 cm (T
1
), 40 cm × 20 cm (T
), 40 cm × 25 cm
(T
3
), 45 cm × 15 cm (T
4
), 45 cm × 20 cm (T

), 45 cm × 25 cm (T
), 50 cm × 15
cm (T
7
), 50 cm × 20 cm (T
8
), 50 cm × 25 cm (T

), 55 cm × 15 cm (T
), 55 cm
× 20 cm (T
11
), 55 cm × 25 cm (T
12
), 60 cm × 15 cm (T
13
10
), 60 cm × 20 cm (T
)
and 60 cm × 25 cm
(T
) were considered for the present study. Data on
different growth and yield attributes were recorded, processed, analyzed and
found having statistically varied. Results showed that the, treatment T
15
showed
significantly the maximum plant height, tassel length and leaf area at silking,
grain filling and at harvest. At silking stage, the T
had the highest area of an
individual leaf 477.9 cm
2
, 879.3 cm
2
and 496.3 cm
15
2
as well as stem dry matter
weight of 28.73 g, 21.35 g and 27.40 g plant
-1
below cob-node, at cob-node and
above the cob-node respectively. The treatment T
showed maximum
biological yield (14.64 t ha
-1
) which was identical to T
13
2
, T
4
and T
in this
respect. T
treatment showed significantly the highest cob length (15.94 cm)
and number of grains row
14
-1
(20.00), but the highest number of grains cob
(231.50), 100 seed weight (29.99 g), grain weight cob
-1
(59.81 g) were recorded
from T
12
. T
11
had significantly the highest grain yield (4.77 t ha
) which
however was not significantly higher than those of T
5
, T
13
and T
(4.62-4.75 t
ha
-1
). As the treatment T
had sparser configuration (60×20 cm) requiring less
seed rate, this configuration may be followed.
