Abstract:
The experiment was carried out in Sher-e-Bangla Agricultural University during
the period from November 2019 to February 2020 to evaluate the influence of
plant density on growth and yield of quinoa. The experiment was laid out in a
Randomized Complete Block design (factorial) with three replications having
three rows spacing as 30 cm (L
1
ii
), 40 cm (L
2
) and 50 cm (L
3
) and four plant
spacing as 15 cm (P
1
), 20 cm (P
2
), 25 cm (P
3
) and 30 cm (P
4
). Data on different
growth parameters, yield components and yield were recorded. The collected data
were statistically analyzed. Seed yield, straw yield and biological yield were
significantly affected by closer row spacing (L
1
) but plant height, number of
branches plant
-1
, number of leaves plant
-1
, dry weight plant
, effective
inflorescences plant
-1
, ineffective inflorescences plant
-1
-1
, seed weight plant
, husk
weight plant
-1
, 1000-seed weight and harvest index were not significantly affected
by row spacing. For plant spacing, 1000-seed weight, seed yield, straw yield,
biological yield and harvest index were not significantly affected but all other
parameters significantly influenced by plant spacing. Results showed that the
highest plant height (67.96 cm at 50 DAS ), number of leaves plant
(16.17 at 25
DAS), number of branches plant
-1
(1.26, 11.44, 16.00 at 25, 50 and at harvest,
respectively), effecetive inflorescences plant
-1
-1
(16.13), seed weight plant
(11.33
g), dry weight plant
-1
(0.17 g at 30 DAS ), ineffective inflorescences plant
(1.42),
husk weight plant
-1
(2.61 g) were recorded from wider spacing of P
3
and lowest
ineffective inflorescence plant
-1
(0.70) was found from plant spacing of P
4
.
Considering interaction effect of row and plant spacing, 1000-seed weight was
insignificant but all other parameters were significantly affected where the highest
seed yield (2.15 t ha
-1
) and straw yield (1.59 t ha
-1
) was recorded in lower row
spacing 30 cm (L
1
) with 20 cm plant spacing.
