One of the major alliaceous crops grown in many tropical nations is the shallot (Allium ascalonium L.). In Ethiopia, it is a significant horticultural product that is used to flavor the regional stew known as "wot" and provides farmers with revenue. However, the productivity of shallot is low at study area due to various limiting factors such as low soil fertility, plant population and lack of improved agronomic practices. A field experiment was conducted to investigate the effect of intra-row spacing and nitrogen fertilizer levels on growth, yield and quality of shallot at Mulo district, Oromia Regional state, Ethiopia during 2021/22 off season. The treatments consisted of four intra-row spacing (5, 10, 15 and 20) cm and four levels of nitrogen fertilizer (0, 50, 100 and 150) kgNha-1 tested in a randomized complete block design with three replications.
