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

), biological yield (4959.20 kg

). From the result of the study, it was revealed that the application of
biofertilizer and recommended N + P combination had a positive impact on
lentil (BARI Mosur-6).
