Full text PDF Potato is the most important tuber crop in Ethiopia. However, its productivity is restricted by inapt intra- and inter-row spacing. This study aimed to assess the effects of intra- and inter-row spacing on potato growth and yield. The experiment utilized three intra-row spacings (20, 30, and 40 cm) and three inter-row spacings (60, 70, and 80 cm) within a completely randomized block design. Irrigation was applied throughout the entire experiment. Data were analyzed using R software version 1.2. The result revealed that intra- and inter-row spacing significantly impacted different features of the crop. A bigger inter-row spacing (80 cm) was comparatively better for growth parameters, but a closer intra-row spacing (20 cm) was better for yield components. A higher total yield (34 t ha-1 ) was obtained with 20 cm × 80 cm spacing. Overall, potato cultivators are advised to employ a 20 cm × 80 cm spacing under irrigation, and further research should be conducted on the effects of spacing.
