Abstract:
A field experiment was conducted at the agronomy field of Sher-e-Bangla
Agricultural University, Dhaka during November, 2013 to March, 2014 to
evaluate the influence of sowing depth and row spacing on germination, stand
establishment and yield of wheat cv. BARI Gom-27. The experiment was
carried out in Randomized Complete Block Design (RCBD) design with three
replications having three sowing depths ( 2, 4 and 8 cm) and four row spacings
(15, 20, 25 and 30 cm). Results showed that sowing depths had significant
influence on emerged seedling m

in the case of grain and straw yield. The highest grain yield (3.98 t ha

highest grain yield (3.81 t ha

) was also produced from 20 cm row spacing,
whereas, 15 cm row spacing
produced the lowest grain yield (3.23 t ha
). The
highest straw yield was observed with 4 cm sowing depth and the lowest with
8 cm sowing depth. As an interaction effect of treatments, 4 cm sowing depth
and 20 cm row spacing produced the highest grain yield (4.53 t ha
