ABSTRACT
Pre-extension demonstration of common bean technologies was
conducted at Fedis and Babile districts of the East Hararghe zone.
One FRG from kebele was established and 10 trial farmers. Both
varieties were sown on 10m*10m plot size with full package
technology. Farmers were trained by researchers. After the provision
of training, farmers were sown on their farms, and regular follow-ups
were undertaken by researchers. The yield performance of the
improved varieties (Awash-2 and serie-125) were 18.26, 23.64 qt/ha
at Ifadin and 20.46, 23.64 qt/ha at Riski kebele respectively. The
result showed that there is a statistically significant difference at 5%
probability level between Awash-2 and serie-125 variety and also
serie-125 has 22.5% yield advantage over Aawash-2. Therefore, it is
better to pre-scale up Awash-2 for the study area and similar
agroecologies because of its color, market demand, and market price
though its yield is lower than serie-125.

INTRODUCTION
Ethiopia is one of the top twelve producers of total
pulse in the world, the third-largest producer of
haricot bean in COMESA member countries, and the
leading exporter in Africa (Agitu, 2014). However,
despite their importance from a community
perspective, caloric intake from consumption of
pulses and oilseeds combined was reported at 9% for
rural and 14% for urban communities (Kebebu, et al.,
2013; Roba, et al., 2015). Of a total of 12.4 million
hectares of farmland in Ethiopia, the majority is used
for the production of cereals (9.16 million hectares); a
relatively small area is seeded to pulses 1.41 million
hectares (FAO, 2019). The current national average
productivity of haricot bean in Ethiopia is 1.48 tons
per hectare which is below average research
demonstrated productivity potential (3.4 tons per
hectare) in the country (Mulugeta et al., 2015). This is
attributed to the combined effects of edaphic,
climatic, disease, and pest problems and the lack of
improved varieties is one of the top problems for low
yield (Gurmu, 2013).
Haricot bean is one of the pulse crops considered the
main cash crop and protein source of many lowlands
and mid-altitude zones of Ethiopia and the crop has a
high nutritional value with important protein contents
(22%), minerals (calcium, copper, iron, magnesium,
manganese, zinc), and vitamins necessary to warrant
the food security of people (Wondimu et al., 2017
and Kabata et al., 2017). The crop is widely grown in
areas between 1400-2000 m.a.s.l. The main
production areas include East Hararghe, West
Wollega, East Shewa, West Arsi, Sidama, Wolayita,
Wollo, and East Gojam (EIAR, 2014).In East
Hararghe haricot-bean is the most important pulse
crop that farmers cultivate as intercropping with
sorghum, maize, and even in some areas in sole.
However, the lack of improved varieties which can
stand with variable climate conditions is the challenge
farmers face. Therefore, this proposal is initiated to
curtail the challenges farmers face in lacking
improved Haricot bean varieties with the
recommended packages.

Objectives
 To evaluate the productivity and profitability of
common bean Technology under farmers’
conditions.
 To create awareness among farmers,
developmental agents, and subject matter
specialists on improved common bean production
technology.
 To collect farmers' and stakeholders' feedback
regarding the technologies
Materials and Methods
This pre-extension demonstration of common bean
was conducted in the Fedis and Babile districts of
East Hararghe Zone.
Description of the study area
Fedis district has a latitude between 8°22’ and 9°14’
North and a longitude between 42°02’ and 42°19’
East, in middle and low land areas: altitude range is
from 1200 – 1600m.a.s.l, with a prevalence of low
lands. The area receives an average annual rainfall of
400 - 804 mm. The minimum and maximum
temperature of the area is 20 – 25o
C and 30 – 35o
C,
respectively. The population’s livelihood mainly
consists of agriculture, husbandry, and small-scale
trade. The farm units are small family holdings with
an average agricultural land area of less than one
hectare. Agriculture is mainly rain-fed. The cropping
system is classified as intensive with cereal mono-
cropping mainly sorghum and maize.
Babile is located at a distance of 31 km from Harar in
the direction of the country’s Eastern part. It is
bordered by Gursum in the Northern, Fedis in the
South, Sumale region in the eastern, Harari region
and Fedis in the western, and Jarso in the
Northwestern. Erer Ibada located on distance of 33
km from Harar and Erer Ibada is located at 09̊ 10̍ 41.5̋̍
North of latitude, 042̊ 15̍ 27.3̋ East of longitude and
elevation of 1274m a.s.l. The physical property of the
soil in the study area is sandy loam (the majority of
the soil in the study area is sandy and an equal
proportion of silt and clay is known as sandy loam).
The climatic condition of this area is almost dry land.
It has a bimodal nature of rainfall. The socio-
economic characteristic of the population in the study
area depends on subsistence agriculture. These study
areas have the potential for the production of
horticultural crops both during the main (rainy)
season and off-season (Belg).
Site and Farmers Selection
Fedis and Babile districts were purposively selected
based on their potential in pulse and oil production.
Ifadin and Riski were selected purposively based on
the potentiality, and appropriateness of the area by
considering lodging, slop’s land escape, access to
road, and suit for repeatable monitoring and
evaluation in the progress of sowing to harvesting.
The selected farmers were grouped in the form of
Farmers Research Group (FRG) with members of 15
(3 male trial farmers and 2 female trial farmers) and
10 farmers working with trial farmers.

Technology evaluation and demonstration
methods/technique
The evaluation and demonstration of the trials were
conducted on farmers’ fields to create awareness
about common bean production. The evaluation and
demonstration of the trials followed process
demonstration approach by involving FRGs,
development agents, and experts at different growth
stages of the crop. The activity was jointly monitored
by FRGs, researchers, experts, and development
agents.
Experimental design
Two improved treatments (Awash-2 & Serie-125)
were replicated across five trial farmers per kebele.
Two improved varieties were sown on 10 trial
farmers' land. 10m*10m plot size of land used from
individual trial farmers for each variety. Each variety
is planted at a spacing of 40cm between rows and 10
cm between plants. Fertilizer rate of 100 kg NPS/ha
and seed rate of 100kg/ha.
Data Collection
Both quantitative and qualitative data were collected
through personal field observation, individual
interviews, and Focus Group discussions using a
checklist and datasheet. The number of farmers who
participated in FRG, yield performance, economic
data, and number of stakeholders who participated in
the training were quantitative data collected while
farmers’ perceptions towards the new technology
were qualitative data collected.
Data analysis
Quantitative data was summarized using simple
descriptive statistics (mean, frequency, and
percentage) while the qualitative data collected using
group discussion, field observation, and individual
interviews was analyzed using narrative explanation
and argument. Data from different sources were
triangulated to get reliable information.

Results and Discussion
Agronomic and yield performance
The following table describes the yield performances of the demonstratedAwash-2 and Serie-125 common bean
varieties across the study sites. The yield performance of the improved Awash-2 variety and serie-125 were
18.26, 23.64, 20.46, and 23.64 qt/ha at Ifadin and Riski kebeles respectively.

Farmers’ Perception
Farmers in the study area selected the best-performing common bean varieties by using their criteria. Farmers set
these criteria after having know-how about the variety and using those criteria they could select the varieties at

harvest time. The opinion of those farmers on varietal preference was collected from participants during the
varieties demonstration. The major criteria used by farmers were maturity, yield, disease tolerance, seed/grain
color, market demand, and market price
Table 6 Ranks of the varieties based on farmers’ selection criteria
Varieties Farmers rank Reasons
Awash-2 1st Medium maturity, high yield, better disease tolerance, white in
seed/grain color, high market demand, high market price
Serie-125 2nd Medium maturity, high yield, better disease tolerance, Red in
seed/grain color, medium market demand, medium market price
Conclusion and Recommendation
The yield of the improved varieties (Aawash-2 and
serie-125) was 18.26, 23.64 20.46, and 23.64 qt/ha at
Ifadin and Riski Kebeles respectively. The average
yield performance of Serie-125 and Awash-2 at both
locations statistically significant differences at 5%
significance level. It is better to disseminate the
variety that has market demand, better market price,
and good color variety for scaling up to enhance
dissemination. Therefore, the agricultural research
center and agriculture office should work in
collaboration on the Awash-2 variety in the study area
and similar agroecology for further promotion.
