Abstract: Durum wheat is one of the industrial crops mainly required for the manufacturing of pasta products; macaroni, spaghetti and semolina. Improved durum wheat varieties suitable for irrigated lowland areas of Ethiopia including Afar and Oromia regions are limited. To overcome this constraint, the recently released 12 durum wheat varieties for rainfed conditions were evaluated across four different locations to confirm their environmental adaptation under irrigation during 2021. Grain yield and yield components, and environmental data were collected and analyzed using R-software. The combined analysis of variance indicated that the varieties differed significantly for all traits except for numbers of kernels per spike. There were highly significant differences among durum wheat varieties in their performances in yield and yield related traits across locations. D2018 (D2018), Toltu and Fetan varieties gave higher grain yield at Werer and Arage (middle Awash) while Denbi, Bullala and Werer1 at Jeju and Merti (upper Awash). Therefore, D2018 could be recommended for middle Awash while Denbi and Bullala for upper Awash areas for large scale cultivation.

Abstract: Soybean (Glycine max (L.) Merrill) is an essential crop in Ethiopia, valued for its role in food production, animal feed, soil fertility improvement, and industrial applications. Despite its growing importance, national average yields remain lower than the global standard due to biotic and abiotic stresses, limited genetic diversity, and the declining potential of released varieties. To address these challenges, the Pawe Agricultural Research Center has introduced and tested various soybean germplasms and commercial varieties from Brazil, the United States, Malawi, and Nigeria since 2010Soybean National variety Adaptation trial comprising of 5 varieties namely; PB12-2, PB12-3, and PB12-9 along with Belessa-95 and Wegayen as a standard check were evaluated at Pawe in 2013 and at Pawe, Humera, Jimma, Assosa, Sirinka and Areka in 2014. Based on the data generated in 2013 and 2014 testing seasons, two promising candidate varieties namely PB12-2 and PB12-3 were selected for their higher grain yield, Number of branches and effective nodules per plant and for other important characters to be verified and evaluated in 2015 cropping season. After extensive multi-location trials, these varieties were officially registered as "Pawe-01" and "Pawe-02" and are now under production in key soybean-growing regions of Ethiopia. Their superior traits make them promising options for enhancing soybean productivity and sustainability in the country.

Abstract: Wheat (Triticum spp) is one the most important and strategic cereal crops in Ethiopia, because of its role in food security, import substitution and used as raw material for the agro-processing. Bread wheat is recently cultivated in the lowland irrigated areas of Ethiopia. Despite many improved bread wheat varieties have been released nationally for rainfed areas, the adaptability of these varieties were not identified. To overcome this challenge, adapatabilty evaluation of recently released bread wheat varieties were condudcted to confirm their environmental adaptation across four locations. Systematic growth, yield and yield components, and environmental data were collected and analyzed using standard agronomic and statistical methodologies. The combined analysis of variance indicated that the sixteen tested varieties differed significantly for all traits except for their numbers of kernesl per spike. Variety Boru (4823.5 and 4566.7 kg ha-1), Dursa (4352.9 and 3950 kg ha-1) and Abay (4078.4 and 4433 kg ha-1) stand out as the highest yielders at Werer and Arage respectively, indicating these varaieteis are best adapted and high yielding next to Ga’ambo-2 (chek) (4352.9 and 4388.3 kg ha-1) in Afar region. Varaiety Biftu (3339.2 and 2965.2 kg ha-1), Dursa (2880.4 and 3122.6 kg ha-1) and Deka (2779.4 and 3087.5 kg ha-1) recorded higher gran yield at Jeju and Merti respectively, indicating these varieties were best performing in Oromia region. High combined mean grain yield was recorded from Boru and Dursa variety (3626.22 kgha-1 and 3563.97 kgha-1) following the standard check variety “Gambo-2” (3781.89 kgha-1) suggesting Boru and Dursa could be used as a widely adapted durum wheat variety with high grain yield to enhance wheat cultivation in irrigated lowland of Ethipia. The lowest grain yield was recorded in variety Wane (3006.37 kg ha-1) and Ardi (2368.87 kg ha-1) suggesting, Wane and Ardi may be less adaptable and low yielder.
