Abstract: Ethiopia is the center of origin and has a varied genetic foundation for Arabica coffee, but there is still a lack of yield-competitive enhanced varieties, which is why the average productivity in the country is significantly lower than the global average. The average national productivity is quite low as a result. To find high-yielding coffee for commercial usage, it may be helpful to further assess the performance of the top-performing selections for growth and yield characteristics at the full bearing stage. Therefore, it is crucial to create pure line coffee types that are stable, disease resistant, and high yielding in order to close this gap and increase coffee productivity. Thus, the purpose of this study was to assess the genotypes of pure lines coffee for yield and yield components. In order to illustrate the growth and yield characteristics of eleven Arabica pure line coffee genotypes and three standard checks, the experiment was carried out at Awada, Leku, and Wonago. A randomized complete block design (RCBD) with three replications was used to carry out the experiment between 2015 and 2020. Data were gathered on plant height, number of primary branches, number of secondary branches, length of the longest primary branch, number of main stem nodes, stem girth, internode length on the main stem, canopy diameter, number of nodes on longest primary, and yield per hectare. The findings showed that there were differences between the growth features. Total plant height (1.88–3.34 m), stem diameter (2.93–4.42 cm), canopy diameter (153.58–195.17 cm), number of main stem nodes (30.47–42.00), primary branch number (59.93–82.93), secondary branch number (12.97–37.80), average length of primary branches (92.50–116.10 cm), and number of nodes on longest primary (18.43–29.07) at Awada. Stem diameter (2.78–4.20 cm), canopy diameter (171.19–216.33 cm), number of main stem nodes (29.27–34.93), inter node length on the main stem (4.99–6.77 cm), number of primary branches (55.67–119.67), number of secondary branches (37.80–76.53), average length of primary branches (90.73–125.07 cm), and number of nodes on longest primary (22.27–61.67) of the plant are all measured at Leku. The number of main stem nodes (27.02-31.13), inter node length on the main stem (6.82 - 14.83 cm), number of primary branches (54.00 - 60.93), number of secondary branches (10.73 - 23.73), average length of primary branches (90.20 - 102.40 cm), stem diameter (2.97 - 3.64 cm), canopy diameter (149.67 - 202.17 cm), and number of nodes on longest primary (20.00 - 25.40) are all measured at Wonago. According to the study's findings, pure line selection 9634 (1684 kg/ha) had the highest overall yield per hectare, followed by 9615 (1671 kg/ha) and 85298 (902 kg/ha), which had the lowest. Awada, Leku and Wonago, there will be a better probability of getting improved pure line Arabica coffee varieties inside south Ethiopian producing climate. To suggest an appropriate and stable pure line variety for coffee growers in the South, the experiment should be conducted again at a different representative trial site.

Abstract: A significant legume crop in Ethiopia, the faba bean (Vicia faba L.) is essential for food security, nutrition, and the livelihoods of smallholder farmers. While there are a number of factors that affect faba bean output, seed sizes and sources have a big impact. In order to give a thorough understanding of these factors, this study synthesizes research data from other studies to investigate the effects of various seed sources and seed sizes on Ethiopian faba bean yield. The potential for production, disease resistance, and adaptation of the faba bean cultivars is significantly influenced by the seed source. Locally adapted seed variations, which are often generated from farmers' own harvests, are generally more resistant to local environmental variables and pests than imported seed varieties. However, locally sourced seeds might occasionally be of uneven quality, which can have a detrimental effect on crop performance. On the other hand, it has been shown that improved seed types have higher yields and are more resistant to disease, which can increase overall production even if they are typically more expensive. The size of the seeds has a major impact on faba bean yield as well. Larger seeds tend to generate robust seedlings and greater germination rates, both of which are necessary for achieving optimal yields. Tiny seeds may occasionally be more appropriate for specific local growing conditions for farmers who have limited access to larger, superior seed varieties. This review describes how maximizing the production of faba bean types can be achieved by selecting the appropriate seed size while accounting for local environmental considerations. This review examines how selecting the appropriate seed size while accounting for local environmental conditions can optimize faba bean yield variations. To boost Ethiopian faba bean productivity, seed size and seed supply must be adjusted. Further research is required to assess the long-term impacts of varying seed sizes and sources under various agro-ecological zones in order to improve the stability and sustainability of faba bean yields throughout the nation.
