Abstract:
In Ethiopia, chickpea is widely grown across the country and serve
s as a multi
-
purpose
crop. Chickpea crop is affected by several diseases but Fusarium wilt caused by
Fusarium
oxysporum
f. sp.
ciceri
is the most serious disease. It caused heavy losses up to 100% in
yield.. The objective of this study was
to evaluate
the
resistance varieties and fungicides
against chickpea fusarium wilt disease
on chickpea
.
. The experiment was arranged in
factorial randomized complete block design
(RCBD) with three replications.
The field
experiment was carried out to evaluate the manageme
nt of three different chickpea variety
Locale, Areriti and Habru with two types of fungicides Thiram and Redomil
including
untreated treatment
.
The experimental materials were us
ed
certified seed, locale seed and
fun
gicides (Thiram as seed treatment and Re
domil as foliar application) as treatments.
Different types of d
ata
(disease incidence, AUDPC, yield and yield components, pathogen
morphological characteristics)
were collected from field and laboratory experiment.
The
data obtained
from experimental fiel
d
were analyzed
by
General Linear Model procedures
using the SAS version 9.2 and least significant difference at p<0.05
.
Based on chickpea
disease occurrence, variety and seed treatment application of fungicide on diseases
incidence was significantly reduc
ed disease development and increased chickpea yield as
compared to the un
-
treated variety. T
he lowest
chickpea fusarium wilt
incidence
(
15.66%
)
was recorded from the Arerti with Thiram application and it was significantly different
(P
< 0.05)
compared
with
the
highest final
fusarium disease
incidence
(
38.7%
)
of
un treated
Local variety treatment.
Thiram used as s
eed
treatment was
the most effective
method
against Fusarium wi
lt disease greater than Redomil
foliar a
pplication. From the main
effect of varieti
es Habru and Arerti significantly reduced
(p
<
0.05)
final disease incidence
compared to Local variety.
This study indicated that chickpea fusarium wilt disease was
significantly affected yield of chickpea, where the untreated plot received
34.38% yield
loss
compared to the best
protected
treatment
.
Among treatments the maximum yield
(49.08qt/ha) was obtained from Areriti with Thiram compared to the minimum untreated
local variety yield (
31.92
qt/ha).
Even though these research results study with only one yea
r
and one location the maximum net benefit of Birr
49330.0
0birr
/ha was obtained from
Arerti
with Thiram
.
Thus, from the economic point of view
on this study could be recommended as a
first alternative for management of chick pea fusarium wilt
