Abstract:
An experiment was conducted at the Farm of Sher-e-Bangla Agricultural University,
Dhaka during rabi season (November to March) of 2018-19 to examine the effect of
nitrogen and sulphur on growth & yield of black cumin (Nigella sativa L.). The
experiment comprised of four levels of nitrogen viz. N
0
(0 kg N ha
(30 kg N
ha
-1
), N
2
(60 kg N ha
-1
) and N
3
(90 kg N ha
-1
ii
-1
), N
) and three levels of sulphur viz. S
(0 kg
S ha
-1
), S
1
(10 kg S ha
-1
) and S
2
(20 kg S ha
-1
). The experiment was set up in
Randomized Complete Block Design (factorial) with three replications. There were
12 treatment combinations in all. Nitrogen and phosphorous levees singly as well as
in combination had significant effect on most of the characters studied. The tallest
plant was recorded at 90 kg N ha
-1
followed by 60 kg N ha
-1
at different growth
stages. Application of 90 kg N ha
-1
gave the maximum primary and secondary
branches plant
-1
, capsules plant
-1
, seeds capsules
-1
, 1000 seed weight and seed yield
of 1446.00 kg ha
-1
. The highest plant height, primary branches plant
, secondary
branches plant
-1
, capsules plant
-1
, 1000 seed weight and seed yield of 1142.00.00 kg
ha
-1
was recorded at 20 kg S ha
-1
closely followed by 10 kg S ha
-1
. Application of 90
kg N ha
-1
coupled with 20 kg S Nha
-1
gave the maximum capsules plant
and seed
yield of 1643.00 kg ha
-1
which was similar to those parameters obtained from 90 kg
N ha
-1
× 10 kg S ha
-1
and 60 kg N ha
-1
× 20 kg S ha
-1
. The highest concentration of
N, K and S in post harvest soil was recorded in the treatment combination of 90 kg N
ha
-1
coupled with 20 kg S ha
-1
.
