Abstract:
A field experiment was conducted at the Sher-e-Bangla Agricultural University,
Dhaka, during November 2021 to February 2022 in Rabi season to examine the
effect of different sowing methods and fertilizer management on growth and yield
of quinoa. The experiment consisted of three sowing methods (viz. M

sowing method, M

- Line sowing method and M
- Bed sowing method) and five

experiment was laid out in split-plot design with three replications. Sowing
methods were allocated in main plots and fertilizer management in sub-plots.
Results revealed that different growth characters, yield and yield contributing
characters of quinoa were significantly influenced by sowing methods, fertilizer
management and their interactions. Among different sowing methods, bed sowing
method resulted in maximum plant height (45.66 cm), dry weight (7.04 g plant

the above results it was appeared that bed sowing method and F
fertilizer level
resulted in highest values in most of the yield attributing characters and their
interaction provided the best seed yield (3.09 t ha

(4.51 t ha
