Onion (Allium cepa L.) is an important vegetable crop in Ethiopia. However, the yields of the bulb crop as well as seed are often constrained by low and imbalanced nutrient supply in soil, particularly nitrogen and phosphorus. Therefore, a field experiment was conducted at the research station of Shire-Maitsebri Agricultural Research Center (SMARC), located in Tselemti Woreda to study the effect of inorganic NP fertilizers and vermicompost on seed yield and seed quality of onion (Allium cepa L.) during 2016/17 dry season under irrigation. The experiment was laid out in a factorial arrangement using randomized complete block design (RCBD) with three replications. Data were collected on seed yield and seed quality. The results revealed that number of umbels per plant, umbel diameter, and number of seeds per umbel, seed weight per umbel and thousand seed weight were significantly affected by the main effect of NP fertilizer rates and vermicompost.
