ABSTRACT The main problem in Ethiopia is food insecurity. The potato has been recognized by the Ethiopian government as a strategic crop to increase food security and farmers' incomes. Potato yields are strongly influenced by agronomic practices such as crop management, fertilizer source and variety. The country's productivity is far below than of the world. Therefore, this study aimed to investigate the effect of fertilizer source and potato variety on growth and tuber yield. The field trial was carried out in a factorial design with the RCBD and repeated three times in each case. The experiment included four fertilizer sources (Control, DAP, NPS and NPSB) and four potato varieties (Local, Gudenie, Belete and Jalenie). During the experiment: data on growth and yield parameters were collected. Experimental results showed that the interaction between fertilizer source and variety was very significant in terms of physiological maturity, number of main shoots, average tuber weight, marketable tuber weight in t/ha and non-marketable tuber yield in t/ha. The interaction of NPBS mixed with the Jalenie cultivar was found to provide a maximum commercial tuber yield of 23.04 t/ha. Because of this, we were advised to use NPSB and urea fertilizer with variety Jalenie to get the maximum marketable tubers yield under condition of little rainfall and a prolonged dry period. |
