Abstract:
A field experiment was conducted at the Agronomy research field, Sher-e-Bangla
Agricultural University, Dhaka from November 01, 2014 to April 30, 2015 to find out
the effect of 4 different vermicompost (Vm) levels viz., Vm

(Courage), V
- BARI Alu-25 (Asterix). The experiment was conducted in spilt plot
Design with 3 replications. The different levels of vermicompost had significant effect
on most of the growth, yield and quality contributing parameters of potato irrespective
of varieties. All parameters studied in this experiment were increased with the
increasing vermicompost levels except water percentage. The variety „BARI Alu-28‟
produced maximum yield (28.89 t ha

) whereas, „BARI TPS-1‟ showed minimum
yield (22.95 t ha
-1
) irrespective of vermicompost levels and other growth, yield and
processing characters also influenced by the different varieties. The results also
revealed that the yield of potato varieties were increased with increasing
vermicompost levels. „BARI Alu-28‟ cultivated with vermicompost 6 t ha
performed
the best results and the same variety with 4 t ha
-1
also showed the statistically similar
results in terms of growth, most of the yield and quality parameters. Among the 16
treatment combination maximum tuber weight (57.18 g) was produced in V
and
the variety Lady Rosetta produced
highest yield (33.86 t ha
-1
), highest marketable
yield (28.78 t ha
-1
) and also produced maximum seed tuber (25.40 t ha
) when
cultivated with 6 t ha
-1
vermicompost. Incase of dry matter, reducing sugar and starch
content, Lady Rosetta showed the best performance compared to those other varieties
when 6 t ha
-1
vermicompost was applied.
