Abstract:
The experiment was conducted at the experimental field of Sher-e-Bangla
Agricultural University, Dhaka during the period from November 2015 to
March 2016 to study the feasibility of reducing chemical fertilizer by using
organic fertilizer in lentil. The experiment comprised of 11 treatments, such as
T
0
: Control condition; T
: All chemical fertilizers as recommended dose (RD);
T

1
: Cowdung as RD + 75% chemical fertilizer as RD; T
: Cowdung as RD +
50% chemical fertilizer as RD; T

: Cowdung as RD + 25% chemical fertilizer

: Poultry Manure as RD + 75% chemical
fertilizer as RD and T
: Poultry Manure as RD + 50% chemical fertilizer as RD
and T

9
: Poultry Manure as RD + 25% chemical fertilizer as RD. The
experiment was laid out in Randomized Complete Block Design (RCBD) with
three replications. Data on different growth characters and yield were recorded.
Among the treatments, all chemical fertilizers as recommended dose (T
) was
found superior considering all yield contributing characters (grain yield, stover
yield) and yield. The treatments T
(Vermi-compost as RD + 75% chemical
fertilizer as RD) and T
8
5
(Poultry Manure as RD + 75% chemical fertilizer as
RD) also showed statistically similar results in respect of grain yield and most
of the yield contributing characters. So, it is possible to reduce the use of
chemical fertilizers by combined use of organic and chemical fertilizers without
significant yield loss in lentil.
