Abstract:
An experiment was conducted at the Agronomy research field, Sher-e-Bangla
Agricultural University, Dhaka from November, 2015 to March, 2016 to study the
performance of wheat-mustard intercropping as influenced by different row
arrangement. Ten treatments were included in this study as, T
1
(sole wheat), T
2
(sole mustard), T
3
(wheat-mustard in 2:1 rows), T
4
(wheat-mustard in 3:1 rows),
T
5
(wheat-mustard in 4:1 rows), T
6
(wheat-mustard in 5:1 rows), T
7
(wheatmustard
in 2:2 rows), T
8
(wheat-mustard in 3:2 rows), T
9
(wheat-mustard in 4:2
rows) and T
10
(wheat-mustard in 5:2 rows). The experimental result indicate that
seed yield of wheat was significantly affected by the wheat-mustard intercropping
system. The highest seed yield (3.4 t ha
-1
) was obtained from T
1
(sole wheat) and
T
4
(wheat-mustard in 3:1 rows). Wheat yield gradually decreased with increasing
mustard rows except T
4
. The lowest seed yield (1.87 t ha
-1
) was obtained from T
7
(wheat-mustard in 2:2 rows) which was statistically similar to T
8
(wheat-mustard
in 3:2 rows). The highest wheat equivalent yield (5.03 t ha
-1
) was obtained from
T
4
(wheat-mustard in 3:1 rows). Treatment T
4
(wheat-mustard in 3:1 rows)
produced the highest LER which was 1.45. Economic analysis of the different
treatments showed that the highest gross return (120250 Tk. ha
-1
), the highest net
return (61178 Tk. ha
-1
) and BCR (2.04) were found in T
4
(wheat-mustard in 3:1
rows). Therefore, present study suggest that wheat and mustard intercropped in
3:1 rows is the most compatible in respect of yield advantage and economic gain.
