Determination of Optimum Plant Density on Yield and Yield Components of Potato (Solanium tubersom L.) in Debub Ari District, Southern Ethiopia

The aim of the study was to determine optimum plant population on yield and yield components of potato in Debub Ari district of south Omo zone, Southern Ethiopia. The study was carried out from 2018 to 2019 cropping season. Three inter-rows spacing (70, 80 and 90 cm) and three intra-rows spacing (30, 40 and 50 cm) were arranged in a randomized complete block design with three replications. Use of 30 cm intra- row spacing and 80 cm inter-row spacing is superior in potato tuber yield (33.40 t ha-1). However, use of 30 cm intra- row spacing and 80 cm inter-row spacing produced optimum tuber yield for potato production in the study area.
