Abstract:
An experiment was conducted at Sher-e-Bangla Agricultural University farm,
Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from March to July,
2019 to determine the effect of potassium and variety on growth and yield of
sesame. The experiment consisted of two factors having 3 levels of potassium
(30, 37.5 and 45 kg K
2
O ha
-1
) as factor-A and 4 varieties (BARI Til 3, BARI Til
4, Binatil 3, Binatil 4) as factor-B, which are laid out in Spilt Plot design with
three replications. Relative water content, total dry matter weight, capsule length,
seed per capsule, 1000-seed weight, seed yield and harvest index were varied
significantly with increasing K level up to 37.5 kg K
2
ii
O ha
-1
(K
2
). The seed yield
and harvest index were 1.16 t ha
-1
and 22.91%, respectively when applied 37.5
kg K
2
O ha
-1
. But the highest stover yield (3.94 t ha
-1
) was recorded with 30 kg
K
2
O ha
-1
. On the other hand, relative water content, leaf dry weight, total dry
matter weight, capsule number, capsule length, 1000-seed weight, seed weight
per plant, seed yield and stover yield were increased significantly in V
2
(BARI
Til 4). The maximum seed yield (1.09 t ha
-1
) and stover yield (4.02 t ha
) was
observed at V
2
(BARI Til 4). The highest seed yield was recorded from the
combination of K
2
V
2
(37.5 kg K
2
O ha
-1
and BARI Til 4) and the combination of
K
1
V
1
(30 kg K
2
O ha
-1
and BARI Til 3) produced the highest stover yield
