Abstract:
An experiment was conducted at the Agronomy field of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period from
October 2008 to March 2009 to evaluate the response of lentil (BARI masur-6)
to different levels of nitrogen and phosphorous. The experiment comprised four
levels of nitrogen viz N
0
(0 kg N ha
-1
), N
1
(10 kg N ha
-1
), N
2
(20 kg N ha
) and
N
3
(30 kg N ha
-1
) and four levels of phosphorus viz. P
0
(0 kg P
(20
kg P

ha
-1
), P
2
(40 kg P
2
O
5
ha
-1
) and P
3
(60 kg P
2
O
5
ha
-1
2
). The experiment was
laid out in a Randomized Complete Block Design (factorial) with three
replications. The data recorded from the experiment revealed that the tallest
plant, the highest branches plant
-1
and dry weight plant
-1
were recorded from (20
kg N ha
-1
(N
2
). The highest pods plant
-1
, 1000 grain weight, grain yield (1768.00
kg ha
-1
) and stover yield (3301 kg ha
-1
O
5
ha
-1
) were also found from 20 kg N ha
.
Regarding phosphorus effect it revealed that the highest value of growth, yield
and yield contributing parameters all were obtained from the application of 40
kg P
2
O
5
ha
-1
. The respective highest values obtained from phosphorus
application at 40 kg P
2
O

ha
-1
were 28.38 cm, 12.99, 10.17g, 109.60, 21.20 g,
1695.00 kg ha

for plant height, branches plant
, dry weight

, pods plant

) and stover yield. In
interaction effect, it was observed that N

P
2
(20 kg N ha

-1
× 40 kg P
)
showed the highest grain yield as 2145.00 kg ha

and stover yield as 3545.00
