Abstract
To study the influence of Biofertilizer, nitrogen and phosphorous on
nodulation, growth and yield of lentil a field experiment was conducted at the
central farm, Sher-e-Bangla Agricultural University, Dhaka-1207, during rabi
season from November 2016 to March 2017. Treatments consisted of two
biofertilizer levels: (i) control and (ii) Biofertilizer (Rhizobium) with six
combinations of nitrogenous and phosphetic fertilizer: (i) No nitrogen +
phosphorous fertilizer (control), (ii) 50% less of recommended N + P, (iii)
25% less of recommended N + P, (iv) recommended N + P, (v) 25% higher of
recommended N + P and (vi) 50% higher of recommended N + P. The
experiment was conducted in two factor Randomized Complete Block Design
(RCBD) with three replications. Growth and yield parameters like plant
height, no of branch plant
-1
, nodule count, dry weight plant
-1
,thousand seed weight, grain yield, stover yield, biological yield etc. were
collected from this experiment. Data were analyzed by MSTAT-C software.
The significance of difference among the treatment means was estimated by
the Least Significance Difference (LSD) at 5% level of probability. Result
revealed that biofertilizer treated plot B
(Biofertilizer) was found superior in
producing maximum plant height, branches plant

biofertilizer and recommended N + P combination had a positive impact on
lentil (BARI Mosur-6).
