Abstract:
A field experiment was carried out at Agronomy Research Field, Sher-e-Bangla
Agricultural University, Dhaka-1207 during the period from December 2020 to March
2021 to study the impact of different agronomic management practices on growth and
yield of quinoa. The experiment comprised of seven agronomic management practices
(no management, no fertilizer, no weeding, no irrigation, no thinning, no pesticides and
complete management) in the plots. The experiment was laid out in RCBD design with
three replications. Significant variation was recorded for fertilizer, weeding, irrigation,
thinning and pest management on growth and different yield contributing characters and
yield of quinoa. The maximum plant height (54.02 cm), number of leaves plant

(1.47 t ha

) were recorded from T
(complete

recorded from T

(no weeding) and highest harvest index (53.19%) were from T
(no
fertilizer) respectively. While the minimum plant height (21.24 cm), number of leaves

yield (0.23 t ha

), biological yield (0.48 t ha
-1
), harvest index (51.06%), were recorded
from T
(no management). No management reduced (84.52%) yield of quinoa that
followed by no irrigation (81.29%), no fertilizer (32.90%), no thinning (13.35%), no
weeding (6.45%), and no pesticide (5.41%) application compared to complete
management.
