Abstract:
A field experiment was accomplished in the Agronomy farm of Sher-eBangla
Agricultural University, Dhaka during the period from November,
2019 to March, 2020 to observe the influence of biofertilizer and different
levels of boron + zinc on growth and yield of lentil. The experiment
comprised of two levels of biofertilizer, (factor A) viz., i) B
= Control
(without biofertilizer), ii) B
= biofertilizer and six levels of B + Zn (factor B)
viz., i) F
0
1
= Control (without B+Zn), ii) F
= B+Zn at 50% of their
recommended dose, iii) F

ii
1
0
= B+Zn at 75% of their recommended dose, iv) F
= B+Zn at their recommended dose, v) F
= B+Zn at 125% of their
recommended dose and vi) F

4
= B+Zn at 150% of their recommended dose
were used in this experiment arranged in split plot design with three
replications. Data on different growth and yield attributes parameters were
taken in which all the treatment showed significant variations. Results
revealed that biofertilizer out yielded over non-biofertilizer applied plot by
producing higher yield which may be attributed to higher plant height (42.79
cm), number of branches plant
-1
(8.92), dry weight plant
-1
(6.47 g) pods plant
(58.32), seeds pod
-1
(1.52), 1000 seed weight (22.51 g), stover yield (4105.33
kg ha
-1
), biological yield (6366.70 kg ha
-1
) and harvest index (34.59 %).
Considering B+Zn levels, F
3
(Recommended B+Zn) and F
(B+Zn, 75% of
recommended doze) gave statistically similar but highest seed yield (2451.81
and 2350.20 kg ha
-1
2
, respectively) than other treatments. These two treatments
also gave higher 1000 seed weight, pods plant
-1
, seeds pod
-1
and branches
plant
-1
. In the case of the combination effect the maximum seed yield
(2552.83 Kg ha
-1
) was recorded from B
1
F
3
.
Thus, it was apparent from the
above results that the treatment combination of B
1
F
was found suitable than
rest of treatment combinations.
