Maize is a major grain crop that is widely adaptable to many agro-ecologies across the world. The goal of the study was to see how adaptable and stable open pollinated maize varieties are in terms of grain yield and yield-related features in the Western Guji Zone's mid-altitude areas. Different genotypes perform differently in each location, which may be used to boost production. Six open pollinated maize varieties were transported from Bako National Maize Research Center and planted in RCBD with three replications at Yabello Pastoral and Dryland Agriculture Research Center's Galana and Abaya sub sites for three years. The results of the analysis of variance revealed that there was a substantial yield difference between genotypes. Gibe-2 had the greatest average grain production of 5.85 t/ha, followed by Kulani with 5.63 t/ha across years and locations, according to the combined analysis of variance. Kulani was found to be the most stable of all the varieties, whereas Gibe 2 was shown to be the most unstable. Kulani's and ABO-additive Bako's main and multiplicative interaction stability values (ASVs) were both near to zero (0.08 and 0.27, respectively), but Gibe 2's ASV was significantly higher (1.62) and deviated from zero. As a result, Kulani was stable and high yielding across settings, whereas Gibe 2 was high yielding in a single environment (unstable). So, and Kulani were recommended for cultivation in the Galana and Abaya districts of southern Oromia, as well as regions with comparable agro ecologies, while Gibe 2 was recommended for the Galana district.

The field experiment was conducted on six improved food barley varieties and one local check at Bule hora woreda, western Guji during 2017, 2018 and 2019 main cropping season

Bread wheat (Triticum aestivum L.) is the most important cereal occupying a protruding position among major food crops in the world in terms of acreage and production and is an important cereal crop which is receives the most attention of specialists in plant breeding and production in the world wide in general and in Ethiopia in particular. This experiment was conducted on five bread wheat varieties Mandoyo, Mada-Walabu, Sofumar, Dure and Sanate against local check at Bule hora woreda to identify and recommend high yielder, insect pest tolerant, and stable varieties. The experiment was carried out in a Randomized Complete Block Design (RCBD), with three replications. Yield and yield related parameters were analyzed using SAS statistical software version 9.0. Most of yields and yield related components were significantly different between the varieties at 5% probability level. Based on the mean separation, the highest average grain yield was recorded from Sanate variety 3926.3 kg/ha while, the lowest average yield (2753.2 kg/ha) was recorded from Local check. From total analysis Sanate variety had a yield advantage over the check (Local). Therefore, we suggest that, farmers, state farms and other private bread wheat producers located at the study areas and with similar agro ecologies are recommended to use Sanate variety to increase bread wheat yield.

Maize is an essential food crop in Ethiopia. The experiment was conducted to establish and select adaptable maize variety with better agronomic performance and to familiarize farmers with improved agronomic practices for moisture stress within the study area. The experiment was conducted on agropastoralists' land by the researcher together with some selected members of agro-pastoralists. Three maize varieties that included MH140, MHQ138 and MH130 were used for the experiment on selected pieces of land. A total of twenty-five farmers were selected from the following Peasant Association for this experiment for both years based on their interest. Five groups were formed based on their closer areas. Each group planted all maize varieties on 10 × 10 m plot size for each variety with a gross area of 100 m 2 after the land was prepared in good manner with the help of expert. Recommended spacing of 75 and 25 cm between rows and plant, respectively was used. Analysis of variance showed significant difference among varieties in days to physiological maturity, plant height, biomass, grain yield, and harvest index. The highest grain yield was obtained from MH130 (6.55 ton/ha) followed by MHQ138 (5.88 ton/ha), while the lowest grain yield was recorded for MH140 (5.02 ton/ha). Based on agro pastoralists perception and selection criteria, MH130 was the first followed by MHQ138. This study states how the pastoralist perceptions were obtained. Therefore, since MH130 is relatively a high yielder and early maturing variety, it is recommended for adoption in Dugda Dawa district and other areas with the same agroecology.
