Abstract:
A field experiment was conducted to study the influence of different
combinations of organic and inorganic fertilizer on growth and yield of
blackgram at the central experimental farm, Sher-e-Bangla Agricultural
University, Dhaka-1207, Bangladesh during March to June, 2017.
Treatments consisted of two combined organic and inorganic varieties viz.
V
1
= BARI Mash-2, V
2
= BARI Mash-3, eight levels of fertilizers viz. F
0
=
Control, F
1
= RDF, F
2
= 25% less than RDF + Vermicompost, F
3
= 50%
less than RDF + Vermicompost, F
4
= 25% less than RDF + Poultry litter,
F
5
= 50% less than RDF + Poultry litter, F
6
= 25% less than RDF + Mixed
fertilizer, and F
7
= 50% less than RDF + Mixed fertilize. The experiment
was conducted following Randomize Complete Block Design (RCBD)
with 3 replications. Results revealed that the growth and yield of blackgram
were significantly influenced by organic fertilizer where variety V
2
and
fertilizers F
2
, F
1
and F
3
gave the highest seed yield (1.83 t ha
,
1.82 t ha
-1
and 1.79 t ha
-1
, respectively). The highest seed yield of the
interaction treatment was attributed to V
2
ii
F
2
followed by V
2
and 1.87 t ha
-1
). It can be concluded that the application of organic and
inorganic fertilizer had a positive effect on BARI Mash-3 and 25% less than
recommended dose of fertilizer + vermicompost or recommended dose of
fertilizer can be suggested to cultivate this crop.
