Background and justifi cation
Barley (Hordeum vulgare L.) is among cereal crops produced in the world [1,2]. There are three subgroups of barley grown; six-row (H. vulgare), two-row (Hordeum distichon) and the rarely cultivated intermediate (Hordeum irregulare). Both tworow and six-row barleys are used for malting,but the best malt quality for beer is produced from two-row varieties [3].
Barley is believed to have been cultivated in Ethiopia before 3,000BC [4,5]. In Ethiopia, it can grow in wide range of agro ecology with an altitude 1800-3400m above sea level but it grows best at altitudes ranging from 2300-3000 m.a.s.l. [3,6]. Barley which includes both food and malt barley species is cultivated in Ethiopia [7]. In Ethiopia, among the cereals, barley is ranked in the fi fth place most important crop next to teff, sorghum and wheat [3,7,8]. Ethiopia is listed in one of the top 10 major barley producing countries in the world [5] and it is the second largest producer of barley in Africa next to Morocco [8].
The majority of barley production is food barley with its share estimated to be 90% compared with malt barley [2], with this Oromia, Amhara, Tigray, and Southern Nations,

Cluster-based improved
Malt barley technology demonstration in selected districts of Arsi and West Arsi zones of Oromia Regional

State, Ethiopia
Nationalities and People's Region (SNPPR) are the main areas of production in Ethipia [9]. In general in Ethiopia, barley grain is used for the preparation of different traditional foodstuffs, such as injera, kolo, and local drinks, such as tela, borde and beer [1,7,10,11]. Malt is the second most important use of barley that is used mostly in beer [3,6].
The major Market shares of barley in Africa are concentrated in three countries-Morocco, Ethiopia and Algeria-accounting for 87% of the total barley production in the continent [8]. In Ethiopia, the market potential and use of malt barley as a row material in brewery factory has increased from year to year [3,6].
In the context of Ethiopia; in general,the demand and supply side of malt barley is not balanced; due to this the brewery and malt factory are forced to import from abroad, in order to satisfy the ever-increasing demand for raw materials and this has a direct and negative impact on hard currency of the country, so in order to minimize the shortage of improved malt barley techinologies this activity was initiated with the following objectives.

General objective
The aim of this study was to contribute for agro-industry

Description of the study areas
The activity was implemented in 4 potential Malt barley producing districts of Oromia regional state in 2019/20 cropping season. In this activity a total of 2 zones were addressed by the LSD of Malt barley technologies.
Arsi zone: Arsi Zone is located in the central part of the Oromiya National Regional State. The zone astronomically lies between 6° 45'' N to 8° 58" N and 38° 32 E to 40° 50'' E. It has 25 administrative districts included [12]. The zone is higly potential for both food & malt barley.
West arsi zone: Is one of the zones of Oromiya Regional State located in central part of Ethiopia, where mixed farming is commonly practiced. The altitude ranges from 500 metres above sea level (masl) to 3200masl. Average annual temperature in the zone ranges between 15 and 20 °C.
The Mean annual rainfall varies between 800 mm and 1400mm [13]. In general the zone is higly potential for both food and malt barley Kofale district in particular.

Demonstration process
Site and farmers selection: From the two zones (Arsi and west Arsi) 4 districts and three of them namely Lemubilbilo, Arsi-Robe and Hetosa from Arsi zone,and one district namely Kofale from West Arsi zone Were selected for the implementation of the activity based on their potential for malt barley production. A total of 5 malt barley clusters which contains 104 hectares of land were formed in collaboration with the districts level experts and "kebeles" level Development Agents (DAs). Then training malt barly production was prepared and delivered the target on farmers. Then improved seed of recently released varity of malt barley called IBON 174/03 was given for the target farmers and planted in LSD program. The areas covered on 104 hectares with malt barley varity. A row planting method was applied with a spacing of 20 cm between rows and a seed rate of 125 kg ha-1 were used. Fertilizer were applied at a rate of 100 kg ha-1 N and 120 kg ha-1 NPS, respectively. All agronomic practices like ploughing, weeding, rouging and other management operations were applied as per the research recommendation.
