Abstract:
The experiment was conducted at Sher-e-Bangla Agricultural University,
Dhaka from November 2018 to May 2019. The experiment consisted single
factor: seven fertilizer management practice with NPK briquettes and
vermicompost viz. T
1
= No fertilizer (control), T
2
= Recommended fertilizers,
T
3
= NPK briquettes as recommended, T
4
= 75% NPK as NPK briquettes + 25%
NPK from vermicompost, T
5
= 50% NPK as NPK briquettes + 50% NPK from
vermicompost, T
6
= 25% NPK as NPK briquettes + 75% NPK from
vermicompost, T
7
= 100% Vermicompost (20 ton/ha). The experiment was laid
out in Randomized Complete Block Design (RCBD) with three replications.
Different fertilizer management practices influenced significantly on all of the
parameters. Among the fertilizer management practices T
4
(75% NPK as NPK
briquettes + 25% NPK from vermicompost) performed best in case of all of
the vegetative (Plant height,number of tillers, number of effective and
ineffective tillers and panicle length) and reproductive characteristics (days to
panicle initiation, no of grain per panicle, no of filled and unfilled grain per
panicle and1000 grain weight) and lowest result was observed from T
1
.
Maximum grain yield as well as straw yield was obtained from T
4
and 7.1 t ha
-1
). Harvest Index was the maximum for treatment T4 (48.9).
