Abstract:
An experiment was conducted at the Agronomy field of Sher-e-Bangla Agricultural
University Dhaka, during October 2018 to February 2019 to evaluate the growth,
yield and yield attributes of white maize (Genotype SAUWMT 12-3-3) under
different planting geometry. The experiment was consisted of two different factors.
Factor A: Row spacings (5) viz. S
1
: 40 cm, S
2
: 45 cm, S
3
: 50 cm, S
: 60
cm, and Factor B: Plant spacings (3) viz. T
1
: 15 cm, T
2
: 20 cm and T
: 25 cm. The
experiment was set up in randomized complete block design (factorial) with three
replications. Results revealed that, growth, yield and yield attributes of white maize
were significantly influenced due to different planting geometry. In case of row
spacings result revealed that, the maximum cob length plant

treatment. In case of
combined effect, S

T
(60 cm × 20 cm) treatment combination performed best in
producing the maximum grain yield (11.07 t ha

) and suitable for grain production of
white maize comparable to other treatment combination. The corresponding lowest
grain yield and yield attributes were recorded in S

T
(40 cm × 15 cm) treatment
combination.
