Abstract:
The experiment was conducted at Sher-e-Bangla Agricultural University,
Dhaka-1207 during the period from November 2017 to March 2018 to examine
the effect of nitrogen, phosphorus and bio-fertilizer on yield and seed quality of
lentil. The treatment consisted of two factors viz. (1) Factor A: two biofertilizer
levels; (i) B
0
= 0 (Control; without Bio-fertilizer) and (ii) B
= Bio-fertilizer (50
gm per 2.5 kg of seeds) and (2) Factor B: six nitrogen and phosphorus levels;
D
0
= Control (without N+P), D
1
= 50% less N+P, D
2
1
= 25% less N+P, D
=
Recommended doses of N+P, D
4
= 25% higher N+P and D
= 50% higher
N+P. The experiment was conducted in randomized complete block design
(factorial) with three replications. A significant variation among the treatments
was found while biofertilizer application and different levels of N+P fertilizers
applied in different combinations. The highest number of pods plant
5
(69.23),
number of seeds pod
-1
(2.12), 1000 seed weight (21.20 g) and seed yield
(2576.60 kg ha
-1
) were obtained from the treatment combination of B
where
the lowest was from B
0
D
. Considering seed quality parameters, all the
parameters were significantly affected by combined effect of biofertilizer and
N+P treatments except percent seed germination and root length. However, the
highest percent (%) seed germination (97.00%), root length (2.95 cm), shoot
length (6.52 cm) and seed vigor index (635.39) was obtained from the
treatment combination of B
0
1
D
. Considering results of the experiment,
application of biofertilizer, along with NPK fertilizer is best producing greater
yield and better quality of lentil seed.
