Abstract:
A field experiment was carried out at the Sher-e-Bangla Agricultural University Farm,
Dhaka-1207, Bangladesh, during the period from November 2016 to March 2017 to study
the effect of vermicompost on growth and yield of wheat under different moisture
regimes with the variety, BARI gom 26. The experiment comprised
of four levels of
irrigation viz., I
0
=
No irrigation (control), I
1
=
ii
Irrigation at18 days after sowing (DAS), I
= Irrigation at 18 and 47 days after sowing (DAS) and I
= Irrigation at 18, 47 and 76
days after sowing (DAS) and three levels of vermicompost viz., V
3
= No vermicompost
(control), V
1
= Vermicompost @ 5 t ha
-1
and V
2
0
= Vermicompost
@ 10 t ha
. The
experiment was laid out in Split Plot Design with
three replications. It was found that I
and V
individually gave the best performance in respect of growth, yield and yield
attributes. The treatment combination of I
2
3
V
2
gave the highest plant height (95.47 cm),
number of tillers plant
-1
(4.90), dry weight plant
-1
(38.70 g), spike length (18.09 cm),
number of spikelets spike
-1
(63.30), number of filled grains spike
-1
(41.58), grain yield
(4.26 t ha
-1
), straw yield (5.78 t ha
-1
), biological yield (10.04 t ha
-1
) and harvest index
(42.43%) at harvest. But the highest 1000 seed weight (48.53 g) and lowest number of
unfilled grains
spike
-1
(5.13) were found from the treatment combination of I
2
V
2
.
