Abstract:
The experiment was conducted at the Sher-e-Bangla Agricultural University, Dhaka-
1207, Bangladesh, from November 2021 to March 2022 to study the effect of
biofertilizer, farm-yard manure, and vermicompost on the growth and yield of BARI
Mosur-6. The experiment comprised of single factor eight treatments viz. T
= Control,
T
1
= Seed inoculation with Rhizobium, T
= Seed inoculation with Azospirillum + PSB
(Phosphate solubilizing bacteria) + KMB (Potassium mobilizing bacteria), T
2
= RDF
(Recommended dose of fertilizer), T
= Seed inoculation with Rhizobium + Azospirillum
+ PSB + KMB, T

= RDF + FYM (Farm-yard manure), T
=
Seed inoculation with Rhizobium + Azospirillum + PSB + KMB + Vermicompost +
FYM. The experiment was laid out in a Randomized Complete Block Design (RCBD)
with three (3) replications. The results revealed that treatment T
(RDF + FYM) exhibited
its superiority compared to other organic, inorganic fertilizers, and synthetic biofertilizers
in terms of seed yield of lentil. Treatment T

showed the tallest plant (39.70 cm), the
highest number of branches plant
-1
(9.30), the highest number of nodules plant
(27.39),
the highest filled pod plant
-1
(69.39), the highest number of dry weight (18.34 g), the
highest amount of 1000 seed weight (26.23 g), the highest seed yield (1.95 t ha
) and
treatment T

(RDF + Vermicompost) gave second highest seed yield (1.91 t ha
), the
highest stover yield (3.57 t ha
-1
), the highest biological yield (5.52 t ha

), and the highest
harvest index (38.57) in this experiment. Farm-yard manure with the recommended dose
of fertilizer application seemed promising for producing a higher yield of lentil.
