“…Additionally, our hypothesis suggests a positive correlation between household size and onion production, as family members contribute valuable labor to onion cultivation activities (Abedullah et al, 2009). Yeshiwas et al (2023) contend that experienced farmers exhibit enhanced management skills, likely contributing to improved production processes. Consequently, we posit that as farming experience, their proficiency in farming and yield enhancement may increase.…”

IntroductionOnion is a significant vegetable crop in Ethiopia, serving as a source of income for smallholder farmers. However, various challenges in the production and post-harvest handling processes impede a consistent supply and marketing of the crop. This study focused on a comprehensive analysis of the onion supply chain, ranging from production to post-harvest handling, to address the existing production and marketing processes. The research initiative was undertaken to map the onion supply chain from farmers to consumers, intending to establish an improved marketing system in northwest Ethiopia.MethodsThe study area covered three onion-producing districts of the Amhara Region. Data collection involved interviews, observations, and market assessments using a structured questionnaire. Sampling followed a multistage technique. The analysis included descriptive statistics and food system analysis to map the supply chain and estimate marketing margins.Results and DiscussionPost-harvest loss in onion production presents a major obstacle in the farming sector, impacting its growth. The study identified six alternative channels for onion marketing where different actors are involved throughout the supply chain. Key stakeholders include farmers, local collectors, brokers, transporters, wholesalers, retailers, and consumers. Packaging and sorting activities are implemented at different supply chain stages to minimize post-harvest losses. Farm-level activities, including curing, sorting, grading, and ventilating, are crucial for reducing losses. The perishable nature of onion bulbs and the existing production and handling challenges exacerbate post-harvest losses. Efforts to address this challenge demand a comprehensive approach, integrating interventions across the value chain, from improved cultivars and storage infrastructure to enhanced market access strategies. Hence, stakeholders and governmental organizations are urged to promote onion value-addition technologies, including the establishment of processing industries. Such endeavors promote collaborative efforts across the onion supply chain, ensuring sustainable benefits for producers and traders.

Indole-3-acetic acid (IAA) is a key plant hormone that plays crucial roles in plant growth and development. This study investigated the effects of exogenous application of IAA as a growth regulator in onion cultivation (Allium cepa L.). Various IAA concentrations were evaluated to determine their effects on onion growth and chemical parameters. Several agronomic properties and chemical parameters, including total fresh weight, plant height, chlorophyll content, nitrates, total phenols, and antioxidant capacity (DPPH), were analyzed. The results revealed that the exogenous application of different concentrations of IAA had a significant impact on onion growth and quality. Specifically, it was found that certain concentrations of IAA fostered a significant increase in fresh bulb weight and a notable elevation in the levels of phenolic compounds. However, the onion’s response to IAA was concentration dependent. In conclusion, the present study offers evidence that the exogenous application of IAA as a growth regulator can enhance onion growth and quality. These findings hold relevance for the advancement of sustainable agricultural practices and can be directed towards crop enhancement.

“…Accordingly, we hypothesized that large family members, male headed households, educated farmers, obtaining access to irrigation, modern inputs, credit, extension service, and being a member of farm cooperative contribute in the operation of farm activities of onion. Farmers who have an oxen enables them to manage their farm lands, and experienced farmers have better administrative abilities that they can exert to their onion production [11,14,15,17,[19][20][21][22][23][24][25][26][27][28] and [29]. The socioeconomic variables examined in this study include gender, age, education, labor force, off-farm income, and the number of oxen owned.…”

“…Several studies conducted at global, national, and regional levels have investigated factors influencing onion production, productivity, and technical efficiency. These studies include [11,14,15,17,[19][20][21][22][23][24][25][26][27][28] and [29]. The studies mentioned above have found that factors such as gender, age, education level, household size, onion purchasing quantity, production experience, land area allocated to onion cultivation, extension services, storage facilities, coordination among producers, access to fertilizers and quality seeds, irrigation services, diseases and pests, plant spacing, soil fertility management practices, and access to credit significantly influence onion production.…”
