Description
A field experiment was carried out for two successive cropping seasons from 2021 to 2022 cropping season at Enchete, Benatsemay woreda, South Omo zone, Southern Ethiopia, to determine optimum plant population on yield and yield components of onion. The experiment involved a factorial combination of three inter-rows spacing (30, 40 and 50 cm) and three intra-rows spacing (5, 10 and 15 cm). The experiment was conducted using a randomized complete block design with three replications. The analysis of data of revealed a non-significant difference due to main and interaction effects on plant height, leaf number per plant and bulb diameter. On the other hand, the significant two-way interaction effects were observed on unmarketable bulb yield, marketable bulb yield and total bulb yield. Based on the result of this study, among nine treatments use of 5 cm intra- row spacing and 30 cm interrow spacing is superior in onion bulb yield (27.63 t ha-1). Therefore, use of 5 cm intra- row spacing and 30 cm inter-row spacing can be recommended for onion producing farmers at Bena-Tsemay Woreda.
