ABSTRACT
One of the fundamental goals of plant breeding is to evaluate genetic diversity in crop species, which aids in the development of breeding approaches. Therefore, this field experiment was conducted to assess mean performance, the genetic variability in garlic genotypes on bulb yield and related traits. The field evaluation of thirteen garlic genotypes and one released variety Holetta local (HL) was conducted at Kulumsa Agricultural Research Center using a randomized complete block design with three replications during the main growing seasons of 2020 and 2021. The analysis of variance indicated there were significant differences among the genotypes for all traits except days to physiological maturity in 2020 season, while only some growth and yield traits are significant in 2021 production season. Some of the genotypes GOG-065/18, GOG-057/18, GOG-047/18, GOG-064/18, GOG-068/18, GOG-045/18, and GOG-018/18 had mean performances higher than the standard check variety Holetta local (HL). Highest phenotypic (PCV) and genotypic (GCV) coefficients of variation recorded for total bulb yield tons per hectare and number of cloves per bulb, while the days to physiological maturity had the lowest heritability (h2b) in broad sense and genetic advance as a percent of mean (GAM), 67% and 33.89% (total bulb yield per hectare) and 1.13% to 0.08% (day to physiological maturity) respectively. High phenotypic and genotypic coefficients of variation coupled with high heritability and genetic advance as percent of mean were observed for total bulb yield tons per hectare number of cloves per bulb and clove weight. Therefore, selection for these characters would be effective for selecting genotypes for future garlic breeding programs.

ABSTRACT
A field experiment was made to evaluate the effects of organic and inorganic fertilizers on the growth and yield of wheat and soil chemical properties. The study was conducted for two consecutive cropping seasons (2023-2024) on farmers’ fields in the Sinana district of Oromia National Regional State. Therefore, this study has attempted to evaluate the effect of the integrated use of vermicompost and inorganic fertilizer on bread wheat production and soil fertility improvement in the study area. Fertilizer source organic Sources of nutrients both included (vermicompost) and inorganic fertilizer (urea and NPS) were used in the integrated form. These treatments consist of: T1 = Control (no input) T2 = Recommend NP, T3 =25% RVC + 75% N + Rec P, T4 =100% RVC + rec P, T5 =50% RVC + 50% N + rec P and T6 =75% RVC + 25% N + Rec P. The experiment was a randomized complete block design with three replications. Soil sampling and agronomic data on wheat grain yield and yield components were collected. Accordingly, the highest mean grain yield (5403.67kgha-1) was recorded from the plot of T2 (Recommended rate from inorganic) flowed by (5186.00 kgha-1) was recorded from T3 (25% RVC + 75% N + Rec P) while the lowest grain yield (2637.67 kgha-1) was recorded from control plot. The partial budget analysis was performed for alternative uses of integrated organic and inorganic fertilizer applications for bread wheat production. The results showed that the application of integrated vermicompost with recommended rates of inorganic NP significantly increased the yield and yield components. It can be concluded that the application of integrated vermicompost and recommended rate of inorganic NP fertilizers (25 % Equivalent N from + 75 % N + Rec P is desirable) based on environmental sustainability for future productivity. This experiment has to be repeated over seasons and locations to make conclusive recommendations for the study area.

ABSTRACT
In Ethiopia, common bean is grown predominantly under smallholder farmers for household consumption, cash crops and to improve soil fertility status. The crop has health benefits being rich in protein and a good source of iron and zinc. In the Amhara region, the crop had many constraints which are limited improved seed supply, poor extension service resulting in quality deterioration, price volatility, the prevalence of white common bean diseases, and rainfall scarcity. Also, the consumption and production of common beans in the West Belesa district weren’t well known. To improve production constraints and consumption problems Gondar Agricultural Research Center (GARC) conducted a demonstration trial in West Belesa district. The main objective was to provide the best adaptive and high-yielder common bean variety; to assess farmers’ and extension workers' reactions to the technology, and to enhance demand-driven technology dissemination. During the experiment, 3 common bean varieties (SER-119, Awash-1, and local) were demonstrated on a 300 m2 plot of land. To evaluate the technology Farmer Research and Extension Group (FREG) was established. The FREG members got training about common bean production, consumption, and crop management as well as the FREG concept and participatory research approaches. The FREG members evaluated the demonstrated technology based on their selection criteria. The selected varieties were SER-119 and Awash-1 varieties were given a mean grain yield of 2200 kg ha-1 and 2783 kg ha-1 respectively. The technology is also visited by farmers and stakeholders. Because of food taste farmers were motivated to produce SER-119 variety in the coming season. So SER-119 variety with a full production package should be promoted to improve income and consumption habits in the district and similar agroecology.
