Effects of inter and intra rows spacing on the growth and yield of potato grown under irrigation system, at Shinta Nursery site, Amhara region, Ethiopia

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.
