Abstract:
The present study was conducted for the effect of organic amendments and
Carbendazim on nodulation and controlling of foot and root rot of lentil in in-
vitro and in-vivo conditions at Sher-e-Bangla Agricultural University, Dhaka,
Bangladesh during the period from November 2018 to May 2019. The experiment
consists of 8 treatments such as T
0
= Control, T
1
= Poultry manure, T
2
= Cow dung,
T
3
=
Spent mushroom compost, T
4
=
Carbendazim 50WP, T
5
= Spent mushroom
compost + poultry manure, T
6
=
Spent mushroom compost + cow dung, T
7
= Spent
mushroom compost + Carbendazim 50WP. BARI masur 4 variety was used in this
experiment. In in-vitro condition, the reduction of mycelium growth was varied
from 12.22% to 36.48% and the highest reduction was recorded in T
7
. In field
experiment, the lowest disease incidence (10.57%) was recorded in T
7
and the
highest disease incidence in control (47.30%). The highest percent reduction of
disease incidence over control was found in T
7
(77.65%)
followed by T
6
(75.58%).
In all cases of yield contributing characters such as number of nodules/plant,
pods/plant, seeds/pod, 1000-seed weight and grain yield increased by the
combination of spent mushroom compost with cow dung. Significantly the highest
yield (1486.70 kg/ha) was found under the treatment T
6
followed by T
7
(1425.70
kg/ha) and T
5
(1403.80 kg/ha), respectively. Carbendazim alone and in
combination of spent mushroom compost with Carbendazim and cow dung were
statistically similar in respect of performance against Foot and root rot of lentil.
